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. Sigmadrive AC 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. |

Sigmadrive Series |
|
|
|
Sigmadrive Series motor controllers are available in traction, pump, and an innovative dual pump and
power steer assist variants. Sigmadrive series controllers offer excellent continuous current ratings
and comprehensive protection from all overcurrent fault conditions due to the high-resolution current
measurement. Sigmadrive series controllers also offer protected contactor drivers with inbuilt coil
suppression. The dual pump models offer a high-power output for the main lift pump, and a secondary
output for the smaller, power steering assist pump.
