Operating Principle The brushed DC servo motor operates via mechanical commutation. Current flowing through the armature windings interacts with the permanent magnet stator field to produce rotational torque. Speed and torque are controlled by regulating armature voltage and current. Optional feedback devices provide position and speed signals for closed-loop control.

Installation Requirements

• Mount on a rigid machine base with precise shaft alignment
• Connect to a compatible DC servo drive with appropriate voltage rating
• Ensure brush access cover remains accessible for maintenance
• Provide adequate ventilation around the motor for cooling
• Observe radial and axial shaft load limits

Usage Notes

• Inspect and replace carbon brushes periodically per maintenance schedule
• Do not exceed maximum voltage and current ratings
• Keep motor interior clean and free of contamination
• Lubricate bearings per manufacturer recommended intervals
• Check commutator condition regularly for wear and damage
