Motor controllers used by uni team

Lynch Motor Company (LMC) has been designing and manufacturing traction motors and generators for over 20 years and is known globally as a specialist in the field of low voltage, high torque permanent magnet DC motors and generators. The company has supported universities throughout the world for many years and its traction motors have been used for numerous Formula Student (FS) electric-powered vehicles.

Having designed the drive system for its CRT01 electric car, the Cardiff Racing team approached LMC for the supply of two LEM-200 72V, 15kW DC motors and two PG Drives Technology Sigmadrive PMT835M controllers. The four-quadrant Sigmadrive controllers are supplying each LMC motor separately with a CANbus link to produce a differential effect and, like a hybrid vehicle, provide instant acceleration and regenerative braking to put energy back into the batteries. The electric drive system on the CRT01 is capable of providing a peak power output of 28.5kW and rated torque of 400Nm at 6000rpm.

PG Drives Technology’s Sigmadrive PM motor controllers provide smooth and predictable speed control of permanent magnet traction motors across a wide range of system voltages and power ratings. Their advanced design includes features such as IMS technology, high-resolution current measurement, CANbus communications and extremely low heat dissipation. The Sigmadrive PM range can also be configured for dual-traction applications and includes a range of dedicated electric power steer assist controllers.
