RS232 open close dc servo motor controller 24v 36v 48v 800w 1000w 1200w 1500w bldc motor controller for Automatic wheelchair
Model:KYDBL4875-1E
1.Overview:
KYDBL4875-1E is an intelligent brushless DC motor controller. It adopts 32-bit high-performance MCU,Advanced motion control algorithm is suitable to the outside of the quadrature encoder input to complete the open loop and closed loop speed, under the closed loop torque of motor sport.Controller with multiple analog input port, the pulse input port and digital I/O port, can through the special software to redefine its functions.Universal RS232 serial port communication, CAN bus, the USB communication, CAN be widely used in automation.
