sigmadrive - induction motor controllers

The Sigmadrive family of AC and DC motor controllers have been developed for a  wide range of electric vehicle applications. The range spans power ratings of 24V, 175A to 80V 650A in three package sizes, each intended to give optimal price and performance.

 

The universal nature of the design enables the same hardware to be easily configured to work as either traction, pump, or steering controller. Furthermore, in total, four different motor technologies are supported:

  1. AC induction
  2. DC series
  3. DC separately excited
  4. DC permanent magnet

FEATURES & BENEFITS

  • 24-80V 175-650A power ratings
  • AC and DC motor control
  • Traction, pump, and steering control
  • Dual traction options
  • Assured gradient control
  • Elegant, low-profile package
  • High power-to-size ratio
  • Exceptional thermal performance
  • High-efficiency, minimal switching losses
  • No internal cables or connections
  • High reliability
  • CANbus communications
  • Built-In coil suppression
  • Proportional, direction, or neutral braking
  • Electromagnetic brake control, hill-hold & restraint 
  • Power steer timer

IMS Technology

Insulated Metal Substrate (IMS) technology is fully utilized to provide state-of-the-art thermal performance and exceptional reliability. The innovative design means there is no internal cabling or inter-board connections and direct heatsinking for all components and terminals.

Control

There is a great deal of flexibility offered by several specialist programmable parameters, thereby ensuring smooth comfortable, control under all conditions. Assured gradient control comes via selectable hill-hold and restraint functions, which are designed to hold the vehicle steady even when no drive signal is present.

CANbus Communication

CANbus communication provides a safe and reliable electrical connection method to gauges, programmers and between controllers themselves. Additionally, the CANbus can be used to load software updates into the Sigmadrive, meaning a vehicle can be upgraded to include new and improved functions.

 

APPLICATIONS

Suitable applications for the Sigmadrive family include: 

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

What is the purpose of an induction motor controller?

An induction motor controller allows a manual or automatic means for selecting and regulating speed, starting or stopping the motor, selecting forward or reverse rotation, regulating or limiting the force, and protecting against faults.

 

What are the features of the controller?

The induction motor controller features a range of input and output options, along with a range of speed settings. Features include: 

  • 7 x low impedance digital inputs
  • 3 x analogue inputs
  • 3 x 3A contactor outputs
  • 3 traction cutback speeds
  • 6 pump speeds

Sigmadrive - AC Induction Motor Controllers

Sigmadrive AC Induction Motor Controllers are tuneable to any AC motor, and uses advanced, real-time high resolution current measurement combined with Sequential Phase Control (SPC) techniques to provide, smooth highly efficient control of torque and speed. SPC provides enhanced performance over other control techniques and is particularly power efficient with highly dynamic loads. The Sigmadrive AC induction motor controller can be quickly set up to provide maximum torque, efficiency and best performance characteristics. The Sigmadrive AC Induction motor controllers are available in traction and pump configurations for the power and voltage ratings shown below. Dual traction applications for all Sigmadrive variants can easily configured using 2 individual traction controllers linked by CANbus.
