Microchip Technology dsPIC33CK Low Voltage Motor Control (LVMC) Development Board (DM330031) provides a motor control development platform using the dsPIC33CK Digital Signal Controllers (DSCs). The LVMC Development Board provides a reference design for Brushless DC (BLDC), Permanent Magnet Synchronous Motor (PMSM), and Internal Permanent Magnet (IPM) motor control applications. The LVMC Development Board is ideal for prototyping motor control applications that operate from 12V to 48V and up to 10A of continuous current. The LVMC Development Board can also support higher current, up to 20A, when used with an optional fan or heatsink.
The LVMC Development Board features the high-performance, single-core Microchip Technology dsPIC33CK256MP506 DSC with 256KB Flash and 8-pairs of advanced motor control PWMs. The DSC also integrates three 3.5Msps ADCs for implementing math-intensive motor control algorithms like sensorless FOC, Initial Position Detection (IPD), and Field Weakening (FW).
The Development Board includes two mikroBUS™ headers, enabling simple expansion to meet a variety of application needs. It also features a high-speed USB to UART interface for debugging purposes and to monitor key parameters in the control algorithm using a graphical PC tool like X2C Scope or RTDM.
The LVMC Development Board supports application development for sensored six-step trapezoidal or sinusoidal control with hall sensors, sensorless BEMF measuring phase voltages, or Field Oriented Control (FOC) with single, dual, or triple-shunt resistor current sensing circuits. This flexibility in architecture enables the user to evaluate various design techniques to suit the application requirements, balancing the cost and performance.
