Description

CHM Submersible Motor.

CHM water submersible motor is water filled 3 Phase induction motor that is designed for driving water submersible pump in reliable quality. The CHM motor is water proof design. All conductors of squirrel-cage of the rotor are made of pure copper bars. And the stator winding is using water proof wires. The thrust bearing is made from special plastic or graphite and thrusts lubricated and cooled by water. This ensured durable operation with heavy load.
