Technical details and manufacturing context for Rotation Motor

Definition
The Rotation Motor is a specialized electric motor designed to precisely rotate the nozzle turret or changer mechanism in industrial equipment, enabling automated switching between different nozzles or tools during manufacturing processes. It converts electrical energy into mechanical rotational energy through electromagnetic induction, typically using a rotor and stator configuration to achieve controlled rotation at specified speeds and torques. The motor is available with a rated power range of 0.75–5.5 kW, rated torque of 5–35 N·m, and rated speed of 1500–3000 r/min. It operates on a three-phase supply voltage of 380 V AC ±10% at 50/60 Hz, conforming to IEC 60038. The insulation class is F (Class H available for high-temperature environments) per IEC 60085, and the protection rating ranges from IP54 to IP65 per IEC 60529. The ambient temperature range is -20 to 40°C, with derating above 40°C and an optional heater for low-temperature operation. Noise level is ≤70 dB(A) at 1 m distance, no load, per ISO 1680. Weight ranges from 15 to 60 kg depending on power and frame size. The mounting type is IM B5 (flange-mounted) per IEC 60034-7, with other types available. Materials include copper windings, steel laminations, and an aluminum housing. Selection should be based on the torque requirement of the turret, ensuring sufficient torque for indexing. Higher speed reduces indexing time. The motor is intended for use in machinery and equipment manufacturing, specifically as a component part. For procurement, verify model-specific values and standards with the legal manufacturer or supplier.
Working Principle
The Rotation Motor operates on the principle of electromagnetic induction. When three-phase AC power is supplied to the stator windings, a rotating magnetic field is generated. This field induces a current in the rotor conductors, creating a torque that causes the rotor to rotate. The speed and torque are controlled by the frequency and voltage of the supply, as well as the motor's design. The rotor is mechanically connected to the nozzle turret or changer, allowing precise indexing and rotation. The motor's construction includes copper windings, steel laminations, and an aluminum housing, which provide efficient magnetic coupling and heat dissipation. The motor is designed to operate within specified parameters, such as rated power, torque, and speed, to meet the demands of the application.
