Microchip Technology has expanded their support for motor control applications with the dsPICDEM MCLV Development Board and two new motor-control software solutions. The dsPICDEM MCLV Development Board is a low-voltage Brushless DC (BLDC) motor-control development platform that supports the dsPIC33F family of motor control DSCs. It provides a cost-effective method for evaluating and developing sensored or sensorless BLDC and Permanent Magnet Synchronous Motor (PMSM) control applications. The dsPICDEM MCLV Development Board (part # DM330021) is available now for $150.00. Source code for the motor-control libraries can be downloaded for free.
The dsPICDEM MCLV Development Board contains a three-phase inverter bridge circuit. The circuit drives a BLDC or PMSM motor using different control techniques, without requiring any additional hardware. The dsPICDEM MC LV board is capable of controlling motors rated up to 48V and 15 Amps, and supports multiple communication channels, such as USB, CAN, LIN and RS-232. It employs a processor-differentiated Plug-In Module (PIM) strategy to support a variety of dsPIC33F motor-control DSCs with different memory and pin configurations. A dsPIC33FJ32MC204 PIM (32 KB Flash and 44 pins) is included with the dsPICDEM MCLV Development Board.
One of the new motor-control software solutions shows how Power Factor Correction (PFC) algorithms can be combined with sensorless motor-control algorithms on a single chip. The second software solution demonstrates how to run an AC Induction Motor (ACIM) faster than its rated speed for a class of applications, to lower cost, save space or reduce weight.
