High efficiency AC/DC controllers
February 1st 2007

Specialist in motor controllers for electric vehicles, PG Drives Technology, on stand 20B61, is launching the new Sigmadrive controller family. These thermally advanced, high efficiency AC Induction and DC motor controllers are designed for forklift trucks, tow tractors and other similar electric vehicle applications.

Sigmadrive AC Induction Motor Controllers are suitable for all AC motors and employ real-time, high resolution current measurement combined with advanced flux control techniques, offering smooth and highly efficient control of vehicle torque and speed.

Insulated Metal Substrate (IMS) technology is fully utilised to provide superior thermal performance and exceptional reliability. The innovative design eliminates all internal links and interconnections, and provides integral heat sinking for all components and terminals. IMS, combined with the latest low-loss MOSFET technology, increases reliability and efficiency thus enabling Sigmadrive to provide a higher continuous current and smaller physical size than other controllers of the same power rating.

Sigmadrive AC Induction motor controllers are available now in three frame sizes for traction and pump applications.
