Title:
SYNCHRONOUS MOTOR
Document Type and Number:
WIPO Patent Application WO/2016/084204
Kind Code:
A1
Abstract:
A hybrid excitation type synchronous motor with high torque density and output density, intended to achieve high efficiency at high speeds, wherein a composite magnetic field formed from a DC excitation magnet excited by a fixed excitation core provided with a DC excitation coil and from a permanent magnet is disposed in a radial air gap or two axial air gaps, the magnetic field fluxes created by the two types of magnets have independent and parallel magnetic circuits formed in the two types of air gaps, torque is created in the magnetic circuits in the same direction through a rotating magnetic field generated by an electromagnetically integrated armature, and as a result, high torque is generated during starting, acceleration, and deceleration.
