TS (NovDec07) - DC Motors

By: Matt Vallez

This month, let’s do some comparing; I am sure all of you have heard the phrase; “let’s compare apples to apples” well it sounds good and everybody uses this analogy to compare whatever it is they happen to be selling at the time. This month I will attempt to demystify the hocus-pocus around electric motors and controllers so we can compare the different brands. I will get us to a point where we are focusing on the real working attributes, not just the rating attributes, or marketing attributes of one electric DC motor manufacture to another, and one controller manufacture to another. Simply stated we will be comparing apples to apples.

 

DC electric motors can be rated in different ways. The NEMA or the National Electrical Manufactures Association has established the standards for ratings of DC motors performed at test intervals of 2 minutes, 5 minutes and one hour. The one-hour rating is also considered the “continuous current rating” Then there is the peak ratting, this is a marketing rating only, designed to allow for tagging the motor with the higest horsepower possible. Imagine the peak rating as the maxim RPMs a new car engine is capable of hitting, say 6,000 RPMs. Above the 6,000 mark on the tachometer the numbers are all red because the engine of this new car is not designed to go that fast. So 6,000 RPMs are the peak. You would not operate that new car at 6,000 RPMs while driving around town. Now think of the continuous rating as the RPMs of the engine under normal driving conditions. The engine, of a new car will operate at between 1,500 and 2,5000 RPMs during normal driving conditions, this is equal to the “continuous current rating”. Now that we have a simple, understandable analogy to use for peak vs. continuous lets apply this in a practical way to rating our electric DC motors.

 

Motors are rated differently depending on the manufacturer. Some manufactures use peak horsepower, which is their own marketing rating scale. As an example; a motor with a peak rating of 11-horsepower, the same motor will have a “continuous current rating” or one hour rating of 4 horsepower. With DC electric motors the rating that will allow us to compare apples to apples is the “continuous current rating”. The “continuous current rating” is at what horse power the motor can continue to run. That is most similar to the RPMs from the new car example we used above, at what RPMs the new car will operate at under normal driving conditions, not what the engine is capable of. GE motors in the Nivel catalog are all rated with a voltage, horse power and then @ a certain RPM. This is a “continuous current rating” the horse power given is something that is sustainable for one hour or continuous. Other manufactures may use different marketing methods to rate their motor products. Some are using much higher horsepower claims. These claims are based on peak performance, not a “continuous current rating”, thus not allowing a true apple to apples comparison using just the horse power numbers provided.

 

Solid state speed controllers are a little different with their own set of rating stats. There is the momentary also known as the peak, 30 second, 1 minute, 90 second, the 2 minute, and the 60 minute also known as the continuous. Most of the OEM manufactures use the two minute rating of their controllers for their marketing. This is done because the 2-minute rating is beyond what would normally be required of the controller, whereas the momentary rating is maximum the controller will put out for a short amount of time, less than 30 seconds. The 2-minute rating is what Curtis, GE and Alltrax use to rate their controllers. When Alltrax states that their AXE4865 is a 650-amp controller, which means it is rated for two minutes at approximately 650 amps. This number is approximate and is usually rounded up to an even number close to the 2-minute actual. In the case of controllers the 2-minute rating is what you want to use so you are comparing apples to apples. Some controller manufactures, just like some motor manufacturers that are out there, want to give themselves an edge. One way is to use their peak rating as the specified numbers they do their marketing with. This makes it more difficult to compare these controllers with other controller manufacturers.

 

The bottom line on this topic is be careful, do not believe all the stats from someone’s marketing literature. Make sure you get the “continuous current rating” when comparing DC electric motors and the “2-minute rating” when comparing controller manufactures s. By getting the real numbers, you will tell be able to know exactly what you are getting. You will then be able to make an informed decision comparing apples to apples.

CART BLANCHE: CUSTOM GOLF CARTS TAKE GAME, PROMOTIONS TO NEW LEVEL

October 3, 2007 - No, it’s not the return of the bullpen car. It’s something much better and more inventive. Custom Caddy Werx in Denver is adding yet another eye-catcher to its fleet of unique golf carts. The Screamer is a fully customizable model shaped like a baseball. You can even add a hat on top.

 

It’s just another example of great rides for the green that are limited only by the imagination of the owner. It joins the ranks of other sports-themed carts already in production, including carts that look like golf balls, basketballs and soccer balls.

 

But those aren’t the only options for Specialty Sports Vehicles (SSVs). If a customer can dream it, Custom Caddy Werx owner Tim Hall can build it. Air conditioning, street-legal light systems, stereos, leather, ice chests cabinets and mini-tows are among common options customers choose.

 

The carts are more than a fun way to mix hobbies, they’re also highly effective marketing tools. They stand out on the links or at special events simply because of their unique designs, but the increased surface area of the sports ball is also the perfect canvas for an ad.

 

They’re also safe, reliable vehicles to get you where you need to go. You can order a brand new cart for customizing, or have Hall fit your vision on your existing one. The custom portion of the cart is crafted from fiberglass, weighs about 100 pounds and is 6 feet in diameter. Custom Caddy Werx can usually complete your custom cart in 4 weeks or less. Prices vary depending on cart and upgrades.

TOMBERLIN PARTICIPATES IN NEW YORK AUTOSHOW

September 23, 2007 - Tomberlin Group breaks new ground with the inclusion of an LSV in the Orchard City Beach Car Show in Orchard City Beach, New York.  For those who do not know what an LSV is, it stands for Low Speed Vehicle.  These vehicles are a new breed of car that is street legal on roads with a posted speed limit of 35mph and below.  Accompanied by Will Castro and the rest of our friends at Unique Autosports from the hit series on Speed Channel, Unique Whips, the Tomberlin E-Merge “emerges” as a crowd favorite.  In a sea of rat rods, custom motorcycles, Lamborghinis, Ferraris, trucks that scrape the ground and some that touch the sky, the Tomberlin E-Merge defeated all as Will Castro’s choice for personal transportation around the show.

 

The benefits of an E-Merge are much the same as automobiles.  It is street legal and features; 4-wheel braking system, independent front suspension, digital speedometer and odometer, high mount stop lamp, 3 point seat belts, windshield wiper, lockable trunk and all D.O.T approved lighting from front to back.  The E-Merge certainly had no problems drawing a crowd.

 

Thanks to Will Castro’s Unique Whips, the transition from cart to car was seamless. Maybe the future will bring an entirely separate category for this innovative mode of transportation, but as the winner for this years LSV category at the Orchard Beach Car Show, the Tomberlin E-Merges victorious.

CS (NovDec07) - E-Z-GO RXV

NovDec07 CoverTHE ALL NEW RXV FROM E-Z-GO

E-Z-GO, a Textron Inc. company and the world’s leading manufacturer of golf cars and utility vehicles, today unveils its new, much anticipated fleet golf car -  engineered to deliver reliability, superior performance, operating efficiency and safety through an array of enhanced features and innovations.

 

The E-Z-GO RXV represents a major step forward in golf car technology. The new vehicle is expected to deliver exceptional value to golf course operators through reduced energy and maintenance costs, and an unsurpassed experience for golfers through best-in-class power, control, comfort and safety. The RXV’s classic yet contemporary lines make it a smart addition to the E-Z-GO family.

 

The RXV is available in electric and gas models. The existing TXT model, introduced in 1995 and the best-selling fleet golf car in company history, will remain a key component in E-Z-GO’s lineup.

 

“Years of intense work and dedication by E-Z-GO’s marketing, design and engineering teams have produced what we believe is the finest golf car ever built,” says John L. Garrison, President of E-Z-GO. “We consider the RXV to be a ‘game changer’ at all levels. Our golf course partners will see even quicker fleet turnaround times, lower energy, fuel and maintenance expenses, and easier upkeep. Golfers will discover a vehicle that rides, handles and stops unlike any golf car they’ve driven, with many new rider comforts. The E-Z-GO RXV delivers the reliability customers expect, the value their operation requires, and the experience their golfers demand.”

 

The numerous RXV innovations, features and benefits include:

AC drive (electric): Unprecedented for an electric golf car, the RXV’s drive train uses an alternating current motor, not the traditional direct current motor, generating more power and longer operating time between battery charges. The RXV is up to 30-percent more efficient than direct-current golf cars, boasting a 48-volt motor - enabling a 10-percent improvement in daily range.

 

Dual-braking system (electric): A fail-safe park brake automatically engages when the RXV stops - requiring no foot pedal engagement. The industry-first auto braking system brakes automatically on steep slopes when needed and can easily hold a 40-percent grade. This “drive-by-wire” system maintains constant speeds safely and easily. The system supplies recharge to the batteries whenever brakes are applied, enhancing efficiency by up to 30 percent, keeping the vehicle on the course longer and reducing long-term operating costs. 

 

Energy transfer bumpers (electric and gas): The RXV features front, back and side bumpers, positioned to minimize damage by absorbing and transferring energy from impacts into the frame rather than the engine or components. The front and rear bumpers are rated to withstand impacts of 5 MPH; side bumpers are rated for 5 MPH collisions.

 

Kawasaki high-performance 13-HP engine (gas): This engine sets new benchmarks for performance — even on the hilliest terrain.  With a larger cylinder and lower RPM, it delivers better fuel economy with less noise. And more miles per gallon mean greater savings for course operators.

 

Warranty: The reliability of the new RXV is backed by the most comprehensive warranty in the industry - four-year, bumper-to-bumper coverage. E-Z-GO’s batteries are guaranteed to last for four years, 1,200 rounds or 21,500 amp hours - whichever comes first - for 36 holes of golf a day, every day.

 

Improved golfer experience: The RXV features an automotive-style, A-arm suspension with coil over spring shock providing a smooth, comfortable ride. It also features added storage space while cup and ball holders are within easy reach of driver and passenger. Redesigned hip restraints and thicker foam padding ensure a comfortable ride; a wider canopy prevents rain from dripping inside the vehicle; a larger bag well accommodates today’s biggest golf bags.

 

Fresh exterior styling: Retaining the classic E-Z-GO look while incorporating up-to-date design elements, the RXV boasts a boldly elegant appearance. Its inviting style makes the RXV as visually appealing as it is enjoyable to drive.

 

Environmentally friendly operation: The RXV electric model requires less energy to charge and operate, minimizing the vehicle’s “carbon footprint” and reducing hazardous waste. And its whisper quiet engine practically eliminates noise pollution. The RXV gas model is compliant with the stringent emissions standards of the California Air Resources Board (CARB) and improves fuel economy by up to 52 percent. The RXV’s seats are made from 100-percent recycled foam.

 

Safety comes first: In addition to the advantages of dual braking and energy transfer bumpers, the RXV has many features designed to keep golfers safe and secure. Its limited slip differential delivers 25-percent better traction and is especially effective on wet or sandy soil. A slip resistant floormat gives golfers firm footing in wet conditions, while the RXV’s canopy has double-wall construction and 50-percent thicker struts.

 

“Our passionate and talented E-Z-GO team considered every mechanical, ergonomic and safety element of the golf car, producing a vehicle of exceptional quality,” Garrison says. “In designing the RXV, we listened to our customers and incorporated their feedback. Our goal was to completely re-imagine the golf car in a way that produced measurable results for course owners, along with performance that truly enhanced the golf experience. I’m proud to say our team has delivered on all counts.”

 

In 1995 E-Z-GO introduced the groundbreaking TXT golf car, which became the best-selling fleet golf car in company history and is a staple at public, private and resort courses worldwide. E-Z-GO first began producing golf cars at its Augusta headquarters in 1954 and has introduced such industry innovations as rack-and-pinion steering, the Precision Drive System, regenerative braking, anti-rollback and diagnostic capabilities.
