Microchip Technology EV12F76A DSPIC33CJ Motor Control Starter Kit

Microchip Technology EV12F76A DSPIC33CJ Motor Control Starter Kit offers a comprehensive solution for quickly prototyping low-voltage 3-phase BLDC motor applications. The Microchip Technology EV12F76A includes a motor control board, a motor, and a USB cable for PC communication. The board also includes a screwdriver for easy motor-to-board connection and a power supply with international plug adaptors, making it an all-in-one solution.

Features

Low-Voltage Motor Control Board (DM330031)
- Three-phase inverter bridge for 12V to 48V motors
  - Three-phase bridge with six NMOS MOSFETs supports 10A of continuous current or 20A with an 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 located on the dsPIC33CK DSC or using the external op amps located 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 and 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
- 12V gate drive power supply
- 5V step-down DC/DC for Hall sensors, an optical encoder, and the mikroBUS™ sockets
- 3V 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 Mikroe 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
