DM330021-2: 3-Phase PMSM Driver, 15A, 40V Max

The dsPICDEM™ MCLV-2 Development Board is targeted to control a brushless DC (BLDC) motor or permanent magnet synchronous motor (PMSM) in sensor or sensorless operation. This flexible and cost-effective board can be configured in different ways for use with Microchip’s specialized motor control Digital Signal Controllers (DSCs) and Microcontrollers (MCUs). The dsPICDEM MCLV-2 Development Board is essentially a backwardly-compatible upgraded version of the dsPICDEM MCLV Development Board.

The dsPICDEM MCLV-2 Development Board supports the dsPIC33F, PIC24F, dsPIC33E, and PIC24E motor control device families. It offers a mounting option to connect a generic 100-pin Plug-In Module (PIM). The board also has a three-phase inverter bridge circuit. The circuit drives a BLDC or PMSM motor using different control techniques without requiring any additional hardware.

The board includes various circuitry to perform the following functions: drive a three-phase inverter that powers the motor phase windings; measure feedback signals (e.g., voltage and phase currents) and provide a suitable fault signal; interface with Hall sensor or quadrature encoder for sensor-based commutation; and communicate with a host computer or an external device via CAN, LIN, USB, or RS-232 interface. The development board supports motors with terminal voltage up to 48V and current up to 15A.
