Three-phase asynchronous electric motors 380 in YE4-112M-4-4KW-IC411

Electromagnetic system

The motor is designed with an optimized electromagnetic circuit for energy efficiency class IE4. The design of the stator slots and rotor rods is designed to reduce additional and no-load losses. The windings are made of high-quality enameled copper wire with class F insulation and vacuum impregnation technology, which ensures high moisture resistance, heat resistance and operational reliability.

Housing and protection

The stator housing and covers are cast from high-strength cast iron, have increased rigidity, reduce vibration and noise. The motor is completely enclosed with a℃of protection IP55, which protects against dust, splashes of water and oil in industrial environments.

Cooling system IC411

Independent air cooling is used: the fan is mounted on a shaft and rotates synchronously with the rotor. The case has reinforced cooling fins to increase the heat transfer area, ensuring stable temperature conditions during continuous operation.

Installation and mechanical part

Version for frame 112, 4-pole (~1500 rpm), rated voltage 380 V, 50 Hz. Mounting dimensions comply with international IEC standards. Low-noise bearings with increased service life are installed, designed for continuous operation S1.

High energy efficiency and cost-effectiveness

Complies with IE4 standard and GB 18613 requirements. Compared with conventional Y, YE2, YE3 motors, the power loss is significantly lower, which provides significant energy savings during long-term operation, especially on pumps, fans and conveyors.

Stability and low failure rate

Optimized design ensures low heat, vibration and noise. The insulation system is resistant to aging, which extends service life and reduces the risk of unscheduled equipment shutdowns.

Good adaptability to operating conditions

IP55 design and cast iron housing allow operation in dusty, humid industrial environments. The engine is universal for machine tools, pumps, fans, conveyors, mixers and other technological equipment.

Versatility and ease of replacement

The mounting dimensions fully comply with IEC standards, so the motor can be easily installed instead of older models Y, Y2, YE3 without reworking the bases and drives.

Ease of maintenance

The design is compact, without complex additional components. It is enough to periodically check the condition of bearings and contacts, which reduces operating costs.
