The Sigmadrive family of speed controllers for induction motors and ancillary products have been developed for use in a wide range of electric vehicle applications, including:

  • Materials Handling
  • Airport Ground Support
  • Industrial
  • Utility
  • Mobile Elevating Work Platforms

WHAT TECHNOLOGY IS USED IN SIGMA MOTORS?

Insulated Metal Substrate (IMS) technology is fully utilized to provide superior thermal performance and exceptional reliability. 

 

It increases reliability and enables Sigmadrive to provide a higher continuous current and smaller physical size than other controllers of the same power rating.

 

HOW ARE THE TRACTION CONTROLLERS LINKED?

Traction controllers are linked by CANbus communication to allow safe and reliable vehicle operation.

 

Multiple Sigmadrives can be interfaced via the CANbus to provide control of all vehicle functions and allow direct interfacing with the ancillary products such as the Sigmagauge LCD vehicle display, Sigma I/O modules, and other third-party equipment to ensure easy system building.

 

HOW TO CONFIGURE THE SIGMADRIVE?

Sigmadrive based systems can be quickly configured using the powerful Hand Held Programmer; this device allows easy set-up using "real" units such as Volts, Hz, Amps, and Seconds.
