Introducing Scott Drive

Development of the Scott Drive Controller began in 2010 with the entry model 450A Scott Drive 100 controller for use with BLDC motors. Since then, the SD100 has undergone extensive testing and development and now also supports Induction and PMSM motors.

The Scott Drive Controller range has been expanded to include two additional medium voltage controllers and one high voltage model which supports DC Bus voltage up to 900V. These controllers are designated the SD200, SD250 and SD300 respectively.

We have a passion for producing the highest quality AC motor controllers for high voltage applications. Every controller model we design is feature rich and employs the latest technology using premium automotive quality components.

SCOTTDRIVE decided to focus solely on AC motor drive and associated management solutions for traction motors. The reasons are the same reasons all major car manufacturers employ AC Motor and Drive technology in their vehicles rather than DC solutions which are higher efficiency, longer life, lower maintenance, smooth and quiet operation.

In addition, AC motors have inherent regenerative braking capability without additional hardware. Regenerative braking coupled with generally higher motor efficiency gives AC electric powered vehicles longer range for the same amount of battery storage.

We believe that the our world needs to move away from internal combustion engine vehicles to electric motor transport and powered machinery.  Scottdrive provides electric motor and battery controllers to assist this move to electric power.

Scottdrive designs and manufactures our motor controller and other products at our factory in Hamilton, New Zealand.

Circuit board components are manufactured to automotive standard and each unit is tested and configured for customer specific requirement on a physical motor to ensure functional compliance prior to shipping.

We’re proud of our design to manufacture facility and are constantly striving to improve our productivity and quality assurance practices.
