DM330021-2

DM330021-2 is a dsPICDEM MCLV-2 development board which 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 specialized motor control Digital Signal Controllers and Microcontrollers. Board supports the dsPIC33F, PIC24F, dsPIC33E, and PIC24E motor control device families. It offers a mounting option to connect a generic 100 pin PIM. The board supports the use of the internal, on chip OpAmps found on certain dsPIC devices or the external OpAmps found on the MCLV-2 board. The board also has a three phase inverter bridge circuit. This board also supports multiple communications channels such as USB, CAN, LIN and RS232. The circuit drives a BLDC or PMSM motor using different control techniques without requiring any additional hardware.

• Three phase inverter bridge with a power rating of 48V/15A
• Hall sensors/quadrature encoder interface for sensored motor control
• Phase voltage feedback for sensorless BLDC operation
• DC bus current sense resistor for single shunt vector control
• Phase current sense resistor for dual shunt vector control
• Overcurrent protection
• Auxiliary power tab fast on connectors for the controller and power stage
• ICSP, RJ11, ICSP programming connectors
• Two LED indicators for debugging purposes
• Auxiliary power tab fast on connectors (BP1 and BP2) for the controller and power stage
