Toshiba has produced a pre-configured development board for creating motor control applications using its ARM Cortex-M3 range of microcontrollers. The partitioning of the double-sided 2.5cm x 5cm board means the TMPM373 microcontroller and high side mosfets are on one side of the board and the gate drivers and low-side mosfets on the other. There is also a current measurement circuit with a 50mΩ shunt resistor and amplifier for current sensing. Digital circuits include a USB-to-serial interface with a default transmission rate of 115kbit/s with a USB connector for a host PC. There is also an RGB LED to indicate motor phase, interfaces for U, V and W motor phase outputs. Cortex-M3 microcontroller The development system, called SigmaBoard, can be used as a starter kit, as a reference design or as a stand-alone system implementing field-orientated control/vector control of br...
