Working Principle
The motor operates based on permanent magnet synchronous motor (PMSM) electromagnetic induction principle. The matched servo drive outputs three-phase sinusoidal variable frequency AC power to the stator winding, generating a rotating magnetic field. The permanent magnet rotor follows the stator magnetic field synchronously to output rotational torque and speed. The built-in optical encoder feeds real-time rotor position and speed signals back to the drive for closed-loop vector control, achieving precise speed and position positioning. When system power fails, the 24V brake coil loses excitation, and the spring pushes the friction disc to clamp the rotor shaft for static load locking.
Installation Mandatory Requirements
- Mounting Form: Standard flange vertical/horizontal mounting, mounting surface flatness tolerance ≤0.03mm
- Shaft Coupling: Use elastic diaphragm coupling to eliminate radial and axial installation offset; rigid coupling is prohibited
- Cable Routing: Separate power cable and encoder signal cable by ≥30cm to avoid electromagnetic interference; all cable connectors must be fully tightened with torque wrench
- Cooling Condition: Ensure ≥10cm natural convection gap around motor housing; forced air cooling required for continuous full-load operation above 45°C ambient temperature
- Brake Wiring: Independent 24VDC power supply for brake circuit, do not share power with motor control circuit
- Vibration Limit: Installation base vibration acceleration ≤0.5g during full-speed operation
Typical Industrial Application Scenarios
- High-speed packaging machinery: Vertical form fill seal machines, labeling equipment, carton folding robots
- Printing & paper processing: Digital printing presses, slitting rewinding machines, die-cutting equipment
- Light industrial robotics: Scara robots, pick-and-place manipulators, desktop assembly robots
- Precision numerical control equipment: Small CNC engraving machines, micro grinding machines
- Food processing automation: Conveyor positioning systems, bottle cap screwing stations
Operation & Maintenance Precautions
- Strictly prohibit running the motor without load coupling for over 30 seconds; no-load overspeed test will damage encoder and bearings
- The holding brake only applies to static load locking; never use the brake for dynamic speed reduction or emergency stop during movement
- Regularly inspect MS connector pin corrosion and cable insulation damage every 3 months for continuous 24/7 operation
- If coolant or dust accumulates on motor housing, clean with dry compressed air (0.4MPa max pressure); water flushing directly onto motor connector is forbidden
- When storing idle motors for over 6 months, charge the brake coil monthly for 30 minutes to prevent brake friction disc rust adhesion
- Do not disassemble motor housing or encoder module without Emerson authorized professional tools; unauthorized disassembly voids product warranty
