Heavy Cast Iron 355 Frame, Total Weight 1650KG
The 300HP three-phase motor adopts an integrated thickened cast iron 355 frame with a net weight of 1650 kg for the whole unit. It features high rigidity and impact resistance, resists deformation under continuous heavy-load operation, and is suitable for heavy-duty working conditions such as crushers and large mixing equipment.
Class F Insulation & Full IP55 Protection
The stator winding of our AC electric motor adopts Class F high-temperature resistant insulation, equipped with a fully enclosed IP55 protection structure that prevents dust and splashing water, enabling long-term stable operation in humid and dusty workshops.
High Power 220KW / 300HP Three-Phase Output
Our 300HP AC motor delivers a standard three-phase power output of 220kW (300 horsepower) with ample starting torque. It is compatible with 380/660V industrial power grids and can be matched with various heavy machinery such as fans, compressors and conveying equipment.

Premium High Efficiency, Long-term Energy Saving
We have optimized the core and winding design of our 220kW three-phase electrical equipment via electromagnetic simulation to meet international premium efficiency standards. The equipment supports 24-hour non-stop operation under S1 continuous duty cycle.
Low Vibration & Quiet Stable Operation
Our AC asynchronous motor features a precisely dynamically balanced rotor and an independent axial flow cooling air duct. Its operating vibration and noise levels are far below industry standards, with minimal fluctuations in rotational speed and torque under long-term full-load operating conditions.
Long Maintenance Cycle, Fit Non-stop Heavy Production Lines
This 300HP asynchronous motor comes standard with heavy-duty wear-resistant bearings, featuring high overall heat dissipation efficiency and controllable temperature rise. It does not require frequent shutdowns for maintenance, making it suitable for non-stop production lines in mining, chemical and metallurgical industries.
