Problems solved by technology
[0003] However, since both the stator coil and the permanent magnet are made into flat disks to reduce the volume, and the relative distance between the stator coil and the permanent magnet is small, due to the consideration of the corresponding rotation, the size of the stator coil and the permanent magnet cannot be increased to increase its output
Therefore, the existing disc permanent magnet motor can only be applied to the output of small power or small horsepower

The invention provides a permanent magnet motor, which comprises at least two first coil modules, at least two first magnetic modules and at least one second magnetic module, wherein the second magnetic module is arranged between the first coil modules; and the second magnetic module is provided with plural second magnetic elements which correspond to the coils of the first coil modules. The second magnetic elements and the coils of the first coil modules can simultaneously generate a magnetic force cutting action so as to improve the output energy of the permanent magnet motor disclosed by the invention. Furthermore, the second magnetic module and the first coil modules are added, so that the output energy of the permanent magnet motor disclosed by the invention is further improved, thus the problem that output energy can not be improved because the coil size and the magnetic element size can not be increased in the prior art can be solved.
Description
technical field [0001] The present invention relates to a motor structure, in particular, to a permanent magnet motor. Background technique [0002] Existing disk permanent magnet motors include a stator coil and permanent magnets, both of which are in the shape of flat disks. Taking the existing disk-type permanent magnet motor as an example, it does not have the iron core and silicon steel sheet of ordinary motors, which can reduce the consumption of iron and the magnetic saturation effect of the core cogging, so it can increase the torque and horsepower of the motor. Moreover, the magnetic pulling force between the stator and the rotor can be eliminated, the load on the bearing can be reduced, and the mechanical loss of the motor can be reduced. Therefore, the existing disc permanent magnet motor can achieve a high efficiency of more than 80%. Moreover, compared with motors of the same level, existing disc permanent magnet motors are small in size and light in weight. ...
