Working Principle

Three-phase variable frequency sinusoidal current output from matched servo drive flows through stator distributed windings to generate rotating magnetic field. Rotor embedded neodymium permanent magnet interacts with stator rotating field to produce continuous electromagnetic torque driving output shaft rotation. Resolver mounted at motor rear end detects real-time rotor electrical angle, feeds analog sine/cosine position signal back to servo drive to close triple control loop, realizing precise speed and position regulation. Optional holding brake engages via spring force when power cut off to lock shaft position for vertical load safety.

Applicable Industries

Metal cutting CNC machinery, automated stamping lines, printing rotary equipment, packaging heavy conveyor axes, plastic injection molding servo axes, woodworking gantry machines, hydraulic press electric servo retrofits

Installation Requirements

  1. Horizontal or vertical flange mounting allowed; vertical shaft downward mounting requires drain plug installation
  2. Mounting surface flatness tolerance ≤0.02 mm per 100 mm flange area
  3. Align motor shaft with load coupling concentricity tolerance ≤0.05 mm radial runout
  4. Power and feedback cables adopt shielded servo cable, cable gland fully tightened to maintain IP65 seal
  5. Motor housing PE ground terminal connected to machine frame with minimum 4 mm² copper wire

Operation Precautions

  1. Do not operate motor above 3000 RPM rated maximum speed to avoid bearing premature wear
  2. Avoid continuous stall operation exceeding 10 seconds to prevent stator winding overheating
  3. Prevent direct coolant splash onto motor terminal housing in machining environments
  4. Brake-equipped variants require dedicated brake power supply circuit per drive manual
  5. Annual bearing grease inspection required for 24-hour continuous production operation
