Thickened Cast Iron Frame
Our 220HP three-phase motor features an integrally cast 315L frame with a net weight of 1044KG. The thicker housing wall delivers high rigidity and excellent vibration resistance, making it suitable for harsh heavy-load working conditions such as mining and heavy-duty conveying.
Multiple efficiency grades IE1, IE2, IE3 available
Our AC motors adopt full pure copper stator windings paired with high-permeability silicon steel sheets. Multiple energy efficiency grades including IE1, IE2 and IE3 are available for selection. The rated power of 160KW features low power loss, and temperature rise remains stable under continuous S1 duty cycle operation.
IP55 Full Protection Structure
Our AC electric motors adopt a design of sealed end covers and corrugated cooling ribs, which provides protection against dust and splashing water. Featuring Class F insulation that withstands high and low temperatures, the motors can operate stably for a long time in dusty and humid workshops.
Heavy-Duty High Torque Output
The 220HP AC motor delivers sufficient starting torque and strong resistance to impact loads. It prevents stalling during full-load operation of crushers and large fans, significantly reducing equipment downtime failures.
Long Service Life & Low Maintenance Cost
Our 3-phase motors are equipped with heavy-duty wear-resistant bearings featuring long lubrication intervals. Their cast iron housings resist deformation and corrosion effectively, drastically cutting the annual maintenance frequency of the complete machines.
Standard Universal Mounting
Our 220HP electric motor adopts the 315L frame that complies with IEC international mounting dimensions, with multiple mounting options including B3/B5/B35. No frame modification is required when replacing imported motors of the same power rating.
Q: This 160KW 315L motor weighs 1044KG, what precautions for lifting and installation?
A: Lifting ring on top is for hoisting only, never lift via terminal box. Install thickened shock-absorbing base plate to ensure coaxiality and prevent premature bearing wear.
Q: How much electricity can IE3 motor save compared with IE2 standard efficiency motor in long-term operation?
A: It saves 3-5 kWh per hour under full load. 24h continuous operation can save over 10,000 kWh per year with short cost recovery period.
Q: What machinery and industries is it suitable for? Can it work outdoors with dust and moisture?
A: Applied to water pumps, compressors, ball mills and large conveyors. IP55 protection fits open-air & chemical dust workshops, not for direct water immersion.
