Evaluation Board for
Motor Driver, Single-phase, PWM,
Full-wave, BLDC Motor
Overview
This evaluation board is designed to provide an easy and quick development
platform for single-phase BLDC motor control applications, using the fol-
lowing devices.
LV88551, LV88561, LV88563
These devices have the closed loop controller for motor rotation speed. And,
potentiometers are provided on this board to configure the mini-
mum/maximum target speed, the speed curve against the input PWM duty
cycle, and some other parameters/options. The potentiometers might be useful
for tuning these parameters and options, otherwise fixed resistors must be
removed and re-soldered.
Setting with fixed resistors is also applicable by disconnecting the potenti-
ometers.
Quick start
The evaluation board is programmed to work standalone without PC. The
following operation allows the operation of most motors with the default
parameters that are preloaded into the device.
step 1.
Connect a motor to J3
step 2.
Connect PWM signal to the pin labeled ‘PWM’
step 3.
Connect a power supply to J4 (J5 is provided optionally for low
power application less than 4A).
step 4.
Turn on power supply
