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:
- AC induction
- DC series
- DC separately excited
- DC permanent magnet
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.
