![]() ![]() The motor is a permanent magnet synchronous three-phase phase motor with 4 pole pairs, capable of 7000rpm and 0.27Nm. The hardware setup comprises of three components: motor, inverter and embedded controller. The steps to use the TI setup to control a motor are detailed on a previous post. My Zynq board would drive the inverter of one motor, whereas a TI TMS320F28379D launchpad would drive the second motor. I decided to write my own algorithm for FOC on a Xilinx Zynq SOC. ![]() TI also provides a library and example projects to drive both motors with Field Oriented Control and Space Vector Modulation. As such, the energy floats between the two inverters (since when one machine is motoring, the second one is in regeneration and vice versa) and an external DC power supply is there to keep a steady DC link voltage and provide power to compensate for the losses for the drive system. They are driven by three-phase inverters (also available by TI), which share a common DC link. TI provides the 2MTR-Dyno, a configuration where two 100W permanent magnet synchronous machines are coupled together. Field oriented control has also enabled this transition, as it enables AC driven machines to be controlled with constant (direct) values and references. Power Electronics for motor control have evolved over the decades: DC machines were replaced by AC induction motors and nowadays permanent magnet synchronous machines (PMSM) are also very popular, in particular in the automotive industry. ![]()
