90kW Motor

What is a 90kW Motor? 

The 90kW three-phase asynchronous motor-equivalent to 122HP-is a large, heavy-duty industrial power unit serving as a core workhorse in sectors such as mining, metallurgy, large-scale waterworks, and heavy-duty building materials manufacturing. Engineered in strict accordance with IEC international energy efficiency standards and GB industrial manufacturing specifications, this series boasts an energy efficiency rating. Unlike standard small-to-medium motors, it is purpose-built for continuous 24-hour heavy-duty operation, high-torque output, and demanding, harsh working environments. Featuring a fully enclosed, high-strength cast-iron housing and a squirrel-cage rotor design, the motor effectively resolves common industry issues associated with high-power units-such as excessive heat generation, efficiency degradation, high vibration and noise, severe starting surges, and high failure rates. Combining exceptional energy efficiency with stability under extreme operating conditions, it is the ideal choice for upgrading power systems in large industrial equipment, replacing aging motors, and supporting export projects.

• Designed for high-torque, heavy-duty applications with excellent starting performance, this motor features a squirrel-cage rotor structure that offers controllable starting current, ample starting torque, and an overload factor of up to 2.0. It easily handles heavy-load startups for equipment such as crushers and ball mills, ensuring smooth, shock-free, and seamless operation while effectively preventing issues like tripping or winding burnout often associated with starting high-power machinery.

• High-level IP55 protection for harsh operating conditions: Featuring an upgraded fully enclosed, dust- and water-resistant design, this motor achieves an IP55 rating-surpassing standard IP54 models. It effectively withstands heavy dust, water spray, oil contamination, and the ingress of debris, making it perfectly suited for extremely demanding environments such as underground mines, open-pit construction sites, high-humidity chemical plants, and high-temperature metallurgical facilities.

• Heavy-duty, thickened cast-iron housing with vibration and shock resistance: The unit features a thickened, high-strength cast-iron casing combined with a structurally reinforced body. It offers exceptional resistance to vibration, impact, and deformation, capable of withstanding the high-frequency vibrations and transient overload shocks typical of heavy-duty equipment, ensuring operational stability far superior to standard light-duty industrial motors.
