dsPICDEM™ MCLV-2 DEVELOPMENT

BOARD USER’S GUIDE

Chapter 1. Introduction

The dsPICDEM™ MCLV-2 Development Board 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 Microchip’s specialized motor control Digital Signal Controllers (DSCs) and Microcontrollers (MCUs). The dsPICDEM MCLV- 2 Development Board is essentially a backwardly-compatible upgraded version of the dsPICDEM MCLV Development Board.

The dsPICDEM MCLV-2 Development Board supports the dsPIC33F, PIC24F, dsPIC33E, and PIC24E motor control device families. It offers a mounting option to connect a generic 100-pin Plug-In Module (PIM). The board also has a three-phase inverter bridge circuit. The circuit drives a BLDC or PMSM motor using different control techniques without requiring any additional hardware. Topics covered include:

• Overview of the dsPICDEM MCLV-2 Development Board

• Features Overview

1.1 OVERVIEW OF THE dsPICDEM MCLV-2 DEV ELOPMENT BOARD

Figure 1-1 shows a simplified block diagram of the dsPICDEM MCLV-2 Development

Board. The board includes various circuitry to perform the following functions:

• Drive a three-phase inverter that powers the motor phase windings

• Measure feedback signals (e.g., voltage and phase currents) and provide a suitable fault signal

• Interface with Hall sensor or quadrature encoder for sensor-based commutation

• Communicate with a host computer or an external device via CAN, LIN, USB, or RS-232 interface

The development board supports motors with terminal voltage up to 48V and current up to 15A. Refer to Appendix B. “Electrical Specifications” for more information on electrical specifi ca tio ns.
