APPLIED TECHNOLOGY CONTROL SYSTEMS IN CONTROL OF ELECTRIC-POWERED VEHICLE DEVELOPMENT


Matthew Moore got involved with the FS team when he started University and decided to approach LMC’s managing director, Trevor Lees, for help during the development programme for the alternative fuel car. Having designed the drive system for the CRT01 electric car, the Cardiff Racing team approached LMC for 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


Via the Lynch Motor Company (LMC), Curtiss-Wright has supplied Sigmadrive motor controllers from PG Drives Technology to Cardiff University’s Cardiff Racing Formula Student team. During 2013/14, Cardiff Racing has been


working on an alternative fuel Formula Student car. The CRT01 is a university research project which the team intends to enter in the 2015 Formula Student event. This year, however, Cardiff Racing’s budget and efforts have been split, with one team continuing the development of an internal combustion powered car for the 2014 FS event, and a second team researching and developing the alternative fuel version. One of the greatest challenges has been the development of an electric drive system. However, following work experience at LMC,


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 are designed to 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.
