    Features:

    • Cooling: Water cooling, Power: 3.7kW, Torque: 1.45Nm, Collet: ER20
    • Voltage: 380V AC at 400Hz, cooled spindle motor speed: 0-24000rpm
      NOTE: *Spindle need to be equipped with VFD to use. Rated frequency of spindle is 400Hz, if you input 220v voltage at 50hz or 60hz, it will damage the spindle and vfd DOES NOT support external resistor.
    • Fast response, strong overload capacity, low noise and high mechanical precision.
    • High quality 4pcs bearings (7005Cx2 + 7003Cx2), runout off less than 0.02mm, tapered bore less than 0.01mm. In extremely high speed working environment, ordinary bearing can not ensure this high rotate speed for using for long time.

    Applications:

    This series water-cooled electric spindle motors are applicable to CNC engraving machines and used for high speed profiling, drilling, cutting, engraving and groove milling of wood, plastics, aluminum, rubber and other materials.
