Product Advantages

For common plant service, the three phase ac asynchronous motor has a direct rotor structure with fewer start-control parts. The IP 54 / IP 55 and open-cooling data are clear in the table, which helps the user match it with normal workshop drives.

Components

Component	Function
Stator	Contains the fixed magnetic core and winding set.
Rotor	Turns with the shaft for steady asynchronous operation.
Frame	Keeps the H355 to H800 assembly aligned on the base.
Bearing system	Carries the rotor load during continuous service.
Cooling section	Provides the IC 611 / IC 616 / IC 81W / IC 86W ventilation path for the body.

Product Applications

Power Plants: Drives coal conveyor belts, coal crushers/pulverizers, induced and forced draft fans, and various auxiliary pumps.
Metallurgy: Used for rolling mills, continuous casting machines, overhead cranes, and blowers; capable of withstanding frequent starts/stops and reversals.
Mining: Used for crushers, ball mills, hoists, and large conveyor belts; delivers high starting torque and offers explosion-proof durability.
Water Utilities: Used for intake pumps, booster pumps, sewage pumps, and aerators; handles water supply, sewage disposal, and irrigation needs.

Motor energy efficiency rating

A motor's energy efficiency rating is a key indicator of energy loss during the conversion of electrical energy into mechanical energy. Which corresponds to the international IEC 60034-30 IE (International Efficiency) classification system; ratings range from IE1 to IE4, with efficiency increasing and energy losses decreasing at each successive level.
