SYNCHRONOUS MOTOR WITH MAGNETIC REDUCTION Russian patent published in 2009 - IPC H02K19/06 H02K19/10 H02K16/00 H02K21/12 

FIELD: electricity.

SUBSTANCE: invention refers to the field of electric engineering, specifically to electric machines, and concerns implementation of synchronous motors exited by constant magnets and can be used as compact aggregate "motor - reduction gear" in mechanical systems with long operational life in impact condition, for example as motor - wheel in ecologically clean vehicles. Suggested synchronous motor contains body, stator pack with teeth and multiphase winding, shaft, interleaving cylinders of rotor and stator consisting of ferromagnetic and non-magnetic elements positioned along axis of rotation. In this device rotor cylinders are mechanically connected with rotor and stator cylinders - with body. At the same time, teeth and ferromagnetic elements of stator cylinders and magnetic conductor teeth and ferromagnetic elements of rotor cylinders have their own identical angle positions. According to the invention, in synchronous motor has been introduced following components: the second stator pack in the form of hollow cylinder with teeth on its inner surface, located outside hollow cylinders shaft with rotor of quick rotation containing high-coercivity constant magnets in the form of rectangular parallelepipeds located in radial direction, magnetised tangentially and oppositely, V-shaped pole tips located between hollow cylinders and stator pack with multiphase winding which pack has converted structure.

EFFECT: improvement of mass-dimensional parametres of these electric motors.
