Mounting & Connection Guidelines

• Isolate all 3-phase 400 V AC drive outputs and auxiliary power sources before handling motor connections or shaft alignment.
• Secure the motor frame to the mounting flange using rated high-tensile bolts, maintaining precise coaxial alignment to prevent radial bearing wear.
• Connect motor power and feedback wiring using shielded multi-conductor cables to suppress electromagnetic radiation.
• Terminate shield braid connections across 360-degree ground clamps at both the drive panel and motor connector housing.
• Verify ambient operating temperatures remain between 0 deg C and +40 deg C to maintain thermal rating without current derating.

Technical Engineering FAQ

• What is the continuous rated power and speed rating for the 3HAC057547-003?

  The motor delivers a continuous rated power output of 4.5 kW at a base rated speed of 1500 rpm under nominal 400 V AC power input.

• What peak current levels can the stator windings tolerate?

  The motor winding tolerates a peak current of 28 A, providing transient peak torque generation up to 84 Nm.

• What type of operating voltage is required for the motor power circuit?

  The motor requires a 400 V AC 3-phase supply delivered through a compatible variable frequency servo drive unit.

• How does ambient operating temperature affect motor output rating?

  Full continuous torque is available from 0 deg C to +40 deg C; operation up to +55 deg C requires current and torque derating.

• What is the line-to-line winding resistance value for testing?

  The stator winding exhibits a line-to-line electrical resistance of 0.8 ohm when measured at ambient conditions.

• What is the rotor moment of inertia specification?

  The mechanical rotor structure features a calculated moment of inertia equal to 0.012 kg m2.

• How is electromagnetic interference prevented in feedback wiring?

  Feedback connections must utilize low-capacitance shielded twisted-pair cabling terminated with full peripheral earth clamps.

• Does the motor support hot-swapping or live disconnection from the drive?

  No, power connectors must never be removed while the drive is energized due to high voltage back-EMF hazards.
