Traction Drive System

Traction Drive System

The traction system uses a Sevcon SEM control rated at 300 amperes. This means that the traction motor, while still a D.C. motor, has no brushes – this reduces service needs for the traction motor.

The motor is custom built by D&D Motor Systems, a leading DC motor manufacturer.

The motor is directly mounted to the rear axle, which is manufactured by Graziano Trasmissioni. This axle model is similar to those used in thousands of small vehicles (like golf carts).

The rear axle features drum brakes on both wheels and incorporates a parking brake as well.

The traction system has been adjusted to provide full travel speed in the forward direction but for safety, the travel speed in the rear or backwards travel direction has been reduced.
