The motors are solidly designed and are maintenancefree for life.The multi-grooved stator contains a threefold winding which, together with the phase-shifting capacitor, creates a symmetrical rotating field at the rated working point of the motor.The rotor is of the squirrel-cage type. Two- or four-pole motors with a variety of design Iengths and diameters provide rated torques from 0.75 to 12.6 Ncm. Can be combined with reduction gear units, brakes, and tachogenerator systems.
