Technical Performance Parameters

Drive System Integration and Bus Synchronization

This motor interfaces directly with drive units communicating across deterministic networks such as EtherNet/IP and Profinet. Real-time feedback integration relies on firmware flash compatibility between the motor encoder electronics and the host drive controller, ensuring low-latency velocity loops and accurate I/O density scaling during high-speed trajectory execution.

Physical Mounting and Wiring Rules

• Disconnect main power to the robot controller and implement lock-out/tag-out before servicing motor connections.
• Align shaft keyway precisely with the axis gearbox input coupling to prevent radial stress on bearings.
• Torque motor flange mounting bolts evenly to specified torque rating to maintain mechanical concentricity.
• Route motor power and feedback cables in separate shielded conduits to minimize electromagnetic interference.
• Connect motor frame earth terminal directly to the robot arm grounding stud with low-impedance bonding wire.

Technical FAQ

• What is the continuous power rating of this motor unit?

  The unit features a 5 kW rated power output when operating on a 400 VAC 3-phase power supply at 50 Hz.

• What insulation class applies to the stator windings?

  The windings are manufactured to Insulation Class F specs, permitting internal operating temperatures up to 155 deg C.

• Is hot-swapping allowed on the motor power cabling?

  Hot-swapping is prohibited. High voltage and residual energy will cause terminal arcing and encoder feedback fault codes.

• What torque factor is generated per unit of current?

  The electromagnetic design produces a torque constant rating of 15 Nm/A across its operating speed range.

• How should cable shielding be terminated at the junction box?

  360-degree metallic cable clamps must secure the braided shield directly to the grounded box housing entry.

• What is the maximum rated operational speed?

  The motor operates at a nominal rated speed of 3000 RPM under variable speed closed-loop drive control.

• What precautions prevent shaft bearing degradation during assembly?

  Avoid axial hammer impacts on the output shaft; always use puller tools during gear coupling installation.

• How does firmware affect motor parameter configuration?

  Drive controller firmware stores specific motor configuration files matching the encoder serial map for precise tuning.
