Double Layer Winding 900 rpm

AC motor with slow rotation are custom and designed and made for special order by customers for specific application, the motors flexibility design are made for high operating efficiencies, use high grade electric-magnetic steel lamination and have excellent corrosion resistance.motors are widely used in multitude industries such as mining, chemical and petrochemical industries, steel industries, pulp and paper etc.

According to the diagram inside, that the winding have six pole, that mean the rotation speed is 900 rpm, each phase divided to six group and every group have two coils, all the coils are in series connection.
