BLD-120 Brushless DC Motor Controller

The detailed information

Description


The BLD-120 is a high performance, cost-effective 3 phase BLDC motor drive

which can provide power output 125VA 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-200 also support     

PWM external input and other speed adjustment methods.

Speed Adjustment Instruction:  


A£®Motor speed adjusted by the internal potentiometer RV

B£®Motor speed adjusted by the external potentiometer

C£®Motor speed adjusted by External analog voltage input

D£®Motor speed adjusted by PWM input:  Pulse duty ratio 10%-90% / Speed linear modulation

Pulse rate: 1K-10K/ pulse amplitude 5V
