dsPIC30F HARDWARE MODULES TO
CONTROL BLDC MOTORS
Micorchip offers a number of hardware tools to help you
implement your own BLDC motor control solution.
FIGURE 3:
PICDEM MC LV BOARD
PICDEM MC LV Board
This board offers a self-contained, low-voltage platform
(Figure 3) that supports all 28-pin motor control
dsPIC30F devices, including the dsPIC30F2010,
dsPIC30F3010 and the dsPIC30F4012. Hardware sup-
port for sensored, as well as sensorless, BLDC motors
is available on this board. The factory shipped board
supports a motor voltage of 24V; however, the
hardware can support voltages from 10V to 40V at
motor currents of up to 4 Amps.
A serial port is available to communicate with an
external source. An MPLAB
ICD 2 In-Circuit Debug-
ger connection is available for programming and
debugging purposes. A potentiometer is available for
speed control, along with two switches for start/stop
control.
On-board power drivers support direct drive to the
BLDC motor. A low-side power resistor supplies current
and Fault feedback to the dsPIC DSC. The “PICDEM
MC LV Development Board User’s Guide”(DS51554)
provides details on the use of this board.
dsPICDEM MC1 Motor Control
Development Board
The dsPICDEM MC1 Motor Control Development
Board (Figure 4), is a general purpose development
board that uses a dsPIC30F6010 to control a wide
range of motor control applications, including sensored
and sensorless BLDC motors. Serial RS-232 and CAN
ports are supported, along with an ICD 2 In-Circuit
Debugger connection for programming and debugging
purposes.
A two-lines by 20-character LCD is used along with four
LEDs for display purposes. Four push buttons and two
potentiometers are available for data entry and feed-
back. Spare analog and digital pins are made available
on two header banks.
No drivers are available on the board, so the MC1
board must be connected to an external drive system.
A 37-pin D-type connector is used to connect the MC1
board to a dsPICDEM MC1H 3-Phase High-Voltage
module (Figure 5) or dsPICDEM MC1L 3-Phase Low-
Voltage module (Figure 6). The D-type connector
connects to external circuitry via opto isolators, thus
allowing for a safe, electrically isolated drive to high
voltage (400 VDC).
The dsPICDEM MC1 Motor Control Development
Board can be used with a dsPICDEM MC1H 3-Phase
High-Voltage Power module to drive a high-voltage
BLDC motor. Refer to the “dsPICDEM MC1 Motor
Control Development Board User’s Guide” (DS70098)
for full details on the capabilities and functions
available on this board.
