YE3-112M-4KW High Efficiency Three Phase AC Induction Motor 1500RPM 50Hz Cast Iron Electric Motor for Industrial Pumps

The YE3-112M-4KW three-phase AC induction motor represents the latest in energy-efficient motor technology. Designed with premium cast iron construction, this motor delivers exceptional durability and performance for industrial applications.

Featuring a 4-pole design with 1500RPM synchronous speed at 50Hz frequency, this motor is optimized for pump applications. The stator and rotor cores utilize high-grade silicon steel plates with excellent surface insulation and low loss characteristics, ensuring superior efficiency and reduced energy consumption.

Our motor incorporates advanced insulation systems with F-class insulation materials, providing excellent heat resistance and extended service life. The winding ends feature high rigidity construction capable of withstanding frequent switching and reversing operations.

The precision die-cast rotor ensures stable operation and consistent performance. The bearing system is carefully designed according to motor type, operational forces, speed requirements, and lubrication needs. For frame sizes up to 250, we use sealed bearings, while larger frames feature open-type bearings that allow for regreasing during operation.

Standard features include:
- Voltage tolerance: ±5%
- Frequency tolerance: ±2%
- Combined voltage/frequency variation: ±5%
