D&D Motor Systems' Robust Designs, Wide Product Line, and Personalized "Engineered Solutions" Have Made them an Aftermarket Electric Motor Leader

      D&D Motor Systems is a privately held New York corporation which designs and manufactures specialty direct current (DC) motors and provides engineering consulting for complete vehicle electric drive & pump systems. D&D Motor Systems offers both stock and custom DC motors that are backed by over 45 years of combined experience in motor design, testing and manufacturing. They also carry a full line of Series Controllers to allow its customers to achieve almost any performance they desire. In addition, they provide state-of-the-art motor testing services if the customers have such a need. Their market focus includes golf cars, utility vehicles, neighborhood electric vehicles, hunting buggies, forklifts, aerial lifts, floor care scrubbers, airport tug vehicles, farming utility vehicles, electric boats, and several other miscellaneous electric vehicle markets.
    Located in Syracuse, New York, D&D Motor Systems is co-owned by Eric Dieroff, vice president of engineering, and Mike Dieroff, president. These brothers were basically born into the electric motor business! Their father Gary Dieroff worked as head engineer for Prestolite and later was a key founder of Advanced DC Motors. Prior to starting D&D Motor Systems, Mike and Eric both worked at Advanced DC Motors. Mike was president and Eric was in charge of engineering. Eric and Mike's skills complement each other well. Eric heads up the engineering and quality control segment of the business while Mike attends to the daily operations.

   D&D prides itself on its technical expertise and uses it to meet customer needs at an affordable price. "If a dealer tells us the vehicle's specifications, expected performance parameters, and budget, we rarely get a dissatisfied customer," says Dieroff.
   Another key distinguishing feature which sets D&D Motor Systems apart from the competition is that they carry the widest selection of electric motors and controllers in the world for the golf car and neighborhood electric vehicle aftermarket. This includes high speed and high torque electric motors for most regenerative braking golf cars (E-Z- GO-DCS, Club Car Regen). Dealers have sought out these types of motors for years with no solution in sight until D&D Motor Systems introduced a line of motor solutions in early 2002. Regenerative braking golf cars include models such as; E-Z-GO: DCS & PDS; Club Car: Regen I & II and IQ. The D&D Motor Systems' motors are designed to enhance either the speed or torque depending on which of their motors are purchased.The motors are designed to draw an amount of current which will minimize the likelihood of the standard controller burning up. Understanding that the regenerative braking controller is the weakest link, D&D Motor Systems plans on adding new 400 and 500 amp E-Z-GO DCS controllers to their product line very soon. This will allow the overall performance of the DCS golf car to be dramatically enhanced. Dealers who have an interest in these new controllers should give D&D a call. D&D Motor Systems' same day or next day delivery service is unsurpassed in the industry. In addition, their robust motor design makes their quality second to none in today's market. The other key factor, which most dealers come back to, is price. Since D&D Motor Systems is the manufacturer and not a distributor (middleman) they are able to provide all these added advantages at prices that are the same or less than the competition.
   D&D Motor Systems' performance speaks for itself. In less than a two-year period, they have added over 600 customers worldwide, delivered over 95% of their orders in less than 24 hours, and have a quality return rate of less than 0.5%. D&D's knowledge and experience translates into satisfied customers.

D&D Motor Systems' mission is straightforward. They want to provide their customers with the best motor and controller solutions for their desired applications. D&D Motor Systems does this by selling the highest quality motors and controllers while providing the best engineering and customer service at highly competitive prices!

D&D Changes How To Choose
A Motor/Controller Combination

  Much of D&D Motor Systems' knowledge and experience was gained by working with various original equipment manufacturers (OEMs) in the material handling, golf car, neighborhood electric vehicle, aerial lift, floor care, airport support, agriculture, electric boat, and several other miscellaneous electric vehicle markets. In working with the engineering departments of these OEM customers, D&D Motor Systems quickly learned to focus on the customers' application and their performance expectations.
  When D&D Motor Systems decided to cater directly to the golf car dealer network they found that many of the dealers asked for motors based just on the motor's horsepower. Unfortunately, horsepower is a confusing measurement for most dealers and customers since it fluctuates depending on a motor's duty cycle rating. Therefore, the same motor could have a horsepower rating of 3.0 and 8.5 depending on whether a continuous or peak duty cycle rating was utilized. Thus to better understand the dealers' needs, D&D Motor Systems decided to market their motor/controller combinations based on easy to understand performance parameters. These key golf car performance characteristics are Speed (mph), Torque (% more than factory), Range (in miles), and Price. Thus the acronym "STRiP" was born, giving the dealers a simple, understandable way to communicate their system needs.

that stands out in any crowd

   Speed is the miles per hour the vehicle will go based on the standard factory differential ratio and tire size. A vehicle's speed can be increased by using larger tires, changing the differential gears – a very time consuming job – or using a bigger motor that only takes 15 minutes to change out! Where controllers are concerned, many people think that bigger means faster. This is not true for non-regenerative braking golf cars.
   Torque helps you carry several passengers and get up the hills! The more torque you have the easier you can stop and restart on steep terrain. Changing the motor, controller, or differential gears can increase torque.
   Range is how far the vehicle can go on a single full charge and is measured in miles. Electrical configuration (36 vs 48 volt), motor/controller type, terrain and driving speed determine how far a vehicle can go. Vehicle ranges could be between 8 and 35 miles depending on the factors listed above.
   Therefore, to ensure that dealers will get a motor/ controller combination that meets their customer's needs, always tell the motor/controller supplier at least the vehicle type & year, the terrain type, and STRiP parameters. Remember, don't talk about horsepower, it's too confusing for the customer. Stick to STRiP!!
