ELECTROMAGNETIC ROTARY DRIVE AND A CENTRIFUGAL PUMP

An electromagnetic rotary drive includes a motor and a control. The motor includes a stator, with which a rotor can be magnetically driven without contact and magnetically levitated without contact with respect to the stator. The rotor is magnetically levitated in a radial plane perpendicular to the axial direction, and the stator has a plurality of coil cores, each of which has a longitudinal leg which extends from a first end in the axial direction to a second end, and a transverse leg which is arranged at the second end of the longitudinal leg and in the radial plane A winding surrounds the longitudinal leg, and the control has electrical energy to control and supply the windings. A thermal separating element is arranged between the motor unit and the control unit, and reduces a direct heat flow from the motor unit into the control unit.
