Brush Air Cooling Spindle Motor PCB Engraver Spindle, PWM Motor Regulator, Fixed Seat 48V 3.175mm ER11 500W


  • to make sure this fits.

  • Can engrave metal or nonmetal

  • Suitable for carving PCB, acrylic, drilling and so on

  • The governor uses a user-friendly terminal, user-friendly flexible wiring, and comes with forced air cooling, you can work for a long time

  • Analog 0-5V control, (unplug the XH2.54-3P potentiometer plug, the signal cable connected to the middle of the XH2.54-3P feet, ground wire XH2.54-3P the right foot)

  • Soft start function to prevent the motor to start the current is too large instantaneous damage with the power supply, (default 0 seconds soft start), 0-5 seconds adjustable
