Overview
The Motor Control Starter Kit (MCSK) provides a complete solution to rapidly prototype a low-voltage 3-phase BLDC motor-based application. By combining a motor control board with a motor, an USB cable for PC communications, a screwdriver for connecting the motor to the board, and a power supply with adaptors for international plug styles, the MCSK provides an all-in-one solution.
Low-Voltage Motor Control Board (DM330031)
- Three-phase inverter bridge for 12 to 48 volt motors
- Three phase bridge with six NMOS MOSFETs supports 10A of continuous current or 20A with additional heat sink or fan
- Three MIC4605 Half-Bridge MOSFET gate drivers (85V)
- Separate Hall sensors and optical/magnetic encoder interfaces for sensored motor control
- Phase voltage feedback for sensorless BEMF BLDC or PMSM operation
- DC bus current sense shunt resistor circuit for single-shunt FOC control or BLDC current control
- Phase current sense shunt resistor in inverter leg for dual or triple-shunt FOC control
- Phase current signal conditioning using the internal op amps locate on the dsPIC33CK DSC, or using the external op amps locate on the LVMC board for current sensing
- Overcurrent protection using the dsPIC33CK DSC’s internal comparator and 12-bit DAC
- DC Bus Voltage feedback for over-voltage protection
- Temperature sensor for monitoring the MOSFET temperature
- Connector to interface external thermocouple (I2C) and an external temperature sensor to monitor the motor temperature
User Interface
- 6 green LEDs for PWM status indication
- 1 Red LED for power-on status indication
- 2 Blue LED for debug indication
- 1 Potentiometer & 3 push buttons to implement user inputs like speed reference, start, stop forward, reverse, etc.
- Reset switch
Power Supply Connectors
- Screw terminal connector to power from an external DC power supply
- Barrel connector to power the board from a 24V/2.5A AC/DC power adaptor
On-board Power Supply
- 12-Volt gate drive power supply
- 5-Volt step-down DC/DC for Hall sensors, optical encoder and the mikroBUS™ sockets
- 3-Volt step-down DC/DC for the dsPIC33CK DSC, serial interfaces and mikroBUS™ sockets.
Communications Interfaces
- UART to USB circuit and connector (mini-B) for high-speed communications for debuggers such as X2C Debug
- Two mikroBUS™ sockets to expand serial communications functionality using MikroElektronika Click boards™
Programming Interfaces
- On-board PKoBv4 Debug Circuit for code programming and debugging, eliminating the need for an external programmer/debugger
- Additional ICSP™ connector for programming the dsPIC® DSC device using an external programmer/debugger
- dsPIC33CK Low Voltage Motor Control (LVMC) Development Board (DM330031)
- Linix 3-Phase BLDC Motor 24V/1.85A/30W with built in Hall sensors
- USB Cable for connection from PC to the board
- Screwdriver for motor connector
- Universal Power Adapter: 100-240VAC 50/60Hz 1.5A input, 24VDC/1.5A/36W output with a positive center barrel 2.1mm tip
