High Speed DC Brushless Motor Controller For 48V 500W Spindle Driver With Analog Speed Regulation And External Potentiometer Or 10V External Control Perfect For DIY CNC Projects And Precision Tooling
✔️ External potentiometer or 0-10V control, 20-50V input, single unit
WS55-220 is a high-speed, cost-effective 3-phase BLDC motor controller designed to drive small spindle motors in CNC projects and precision tooling. It accepts DC 20V to 50V and offers two independent speed regulation modes: external potentiometer or 10V external control signal, and they cannot be used at the same time. This makes it handy for hobbyists building DIY CNC rigs where you want smooth, adjustable spindle RPM with minimal noise.
✅ 20-50V DC input range for three-phase BLDC motors
✅ Two speed regulation modes: external potentiometer or 0-10V control
✅ Protection: phase line short, overvoltage, over-current, locked-rotor
✅ High-speed operation with low noise and low vibration
