Servo motor power cable is a specialized electrical cable designed to transmit high-current electrical power from a servo drive (amplifier) to a servo motor. Its primary function is to deliver the precise voltage and current required to drive the motor windings and generate controlled torque and motion
Servo motor power cable Features:
Conductors: Typically contains 2, 3, or 4 heavily stranded, fine-gauge copper conductors (often tinned for corrosion resistance). Stranding provides flexibility.
3 Conductors: Most common (U/V/W phases for 3-phase AC servo motors).
4 Conductors: Used for motors requiring a separate ground/earth conductor within the same cable (U/V/W + PE).
2 Conductors: Less common, sometimes for specific DC servo types or brake circuits.
Insulation: High-quality, durable insulation materials (e.g., PVC, PUR, TPE) rated for the motor voltage (commonly 300V, 600V, or 1000V) and resistant to oils, chemicals, abrasion, and temperature extremes (often rated -40°C to +80°C or higher).
Shielding: Robust overall braided or spiral shield (usually tinned copper) is essential. This: Contains electromagnetic interference (EMI) generated by the rapidly switching high currents in the cable. Protects the motor’s feedback signals (encoder/resolver) running in separate cables from electrical noise, ensuring accurate position/speed control.
Jacket (Sheath): A tough outer jacket made of materials like PUR (Polyurethane) or PVC (Polyvinyl Chloride). PUR is preferred for demanding applications due to its superior: Flexibility: Critical for continuous motion applications (robotics, CNC). Abrasion Resistance: Withstands rubbing against machinery. Oil & Chemical Resistance: Protects against industrial contaminants. Tear Resistance: Prevents damage during installation/use.
Flexibility: Designed for high-flex or continuous flex applications common with servo systems in automation and robotics. Fine stranding and specialized jacket materials achieve this.
Connectors: Terminates in industry-standard connectors compatible with the servo drive output and motor input (e.g., circular connectors like M23, M17, M12; rectangular types; or sometimes flying leads for direct termination). Proper grounding/shield termination at BOTH ends is crucial for noise immunity.
