Two pole induction motors are used for regenerative monoset pumps. Designed under pressure and rigidly locked inside the frame, the motor stator is constructed from silicon steel laminates with a low watt loss. Featuring enamelled copper wire wound between varnish-impregnated copper wire, these windings offer excellent resistance. Using quality materials and construction techniques ensures that motors perform well and reach a low temperature rise, thereby extending their useful life.
