The invention discloses a parallel type double-
stator hybrid excitation
permanent magnet motor, and belongs to the technical field of permanent
magnet motors. The parallel type double-
stator hybrid excitation
permanent magnet motor comprises a shell, a motor set A and a motor set B, and is characterized in that the motor set A and the motor set B are arranged in the shell in a parallel mode, a
stator A of the motor set A is provided with a winding A with a high back
electromotive force, a rotor A is provided with an NdFeB permanent
magnet, the motor set A selects an
operating point with low rotating speed and
high torque to act as a rated
operating point A, and control is performed by adopting a weak magnetic
control mode when the rotating speed exceeds the rated
operating point A; and a stator B of the motor set B is provided with a winding with a
low back electromotive force, a rotor B is provided with an
AlNiCo permanent
magnet or a ferrite permanent magnet, the motor set B selects an operating point with high rotating speed and capable of meeting the high-speed
load bearing capacity to act as a rated operating point B, and control is performed by adopting a magnetic link
control mode when the rotating speed exceeds the rated operating point B. The parallel type double-stator
hybrid excitation
permanent magnet motor not only has the characteristics of
low speed and
high torque, but also has the characteristic of high-speed running. Meanwhile, the parallel type double-stator hybrid excitation permanent magnet motor has the characteristics of wide rotating speed range and high efficiency, and can improve the energy
utilization rate of a
system.
