 This motor drive reference design kit (RDK) is composed of three power boards (STEVAL-IHM003V1, STEVAL-IHM004V1 and STEVAL-IHM005V1) that can be driven by a single control board via six in-line connectors. It has been designed around the ST7FMC dedicated microcontroller for motor control which offers significant advantages compared to other microprocessor based approaches such as DSPs. The control board supports several applications with six-step commutation or 6-signal PWM (sine wave-modulated) outputs, including: 3-phase AC induction motor control, 3-phase BLDC/AC PM motor control (6-step sensorless) and 3-phase BLAC PM motor control (sinusoidal driven, with hall sensors). |
