Working Principle

1. Electromagnetic Rotation Driving Principle: The three-phase alternating current output by the matched PacDrive servo drive flows into the motor stator three-phase winding, generating a rotating alternating magnetic field inside the stator cavity. The permanent magnet installed on the motor rotor interacts with the stator rotating magnetic field to generate continuous electromagnetic torque, driving the rotor and output shaft to rotate synchronously with the stator magnetic field.
2. Closed-Loop Position Feedback Principle: The absolute encoder installed at the motor rear end rotates synchronously with the rotor, real-time collect the absolute angle position of the rotor, transmit digital position feedback signals to the matched servo drive through serial bus. The servo drive compares the target position command and actual rotor absolute position, adjust the three-phase output current phase and amplitude in real time through closed-loop PID algorithm, eliminate position and speed error, realize high-precision servo positioning control.
3. Over-Temperature Protection Working Logic: The temperature sensing switch attached to the stator winding insulation layer real-time detect winding operating temperature; when the temperature rises to 130°C protection threshold, the temperature switch is disconnected, send fault alarm signal to the servo drive, the drive immediately stops outputting three-phase driving current to the motor, prevent winding insulation melting and motor permanent magnet demagnetization damage.

Operation & Maintenance Precautions

1. Before equipment trial run, manually rotate the motor output shaft to check for jamming, abnormal friction noise; strictly prohibit power-on operation when the shaft is stuck
2. Regularly check the servo coupling fastening screws every month, prevent loose coupling caused by high-speed vibration leading to coaxiality deviation and motor bearing damage
3. Do not disassemble the motor rear end encoder cover privately; disassembly will damage the absolute encoder sealing structure and cause loss of power-off position memory function
4. When cleaning production line equipment, standard IP54 motor must avoid direct high-pressure water gun flushing the motor shell and connectors; only use dry cloth to wipe dust on the shell surface
5. If the motor reports over-temperature fault frequently during operation, check whether the surrounding air circulation space is blocked by production line fixtures, remove obstacles to restore heat dissipation air flow
6. Long-term shutdown storage of spare motors must be placed in dry constant temperature warehouse, motor output shaft coated with anti-rust grease, encoder connector covered with dustproof protective cap
7. Motor winding insulation resistance test must be carried out every six months for equipment running all year round; insulation resistance lower than 1MΩ indicates insulation aging, need to replace the motor in time
