BLD-300B Brushless DC Motor Controller

The detailed information

Description


The BLD-300B is a high performance, cost-effective 3 phase BLDC motor drive

which can provide power output 300VA max. The design is based on advanced DSP 

technology and feature high torque, low noise, low vibration, PID speed loop, PID 

current loop, over current protection, over load protection. The BLD-300B also

support RS232 communication Protocol to set motor run-up time, etc.
