Title:
MOTOR USING PERMANENT MAGNET
Document Type and Number:
WIPO Patent Application WO/2019/198975
Kind Code:
A1
Abstract:
The present invention arranges a rotor core in a cylindrical form to have a hollow portion therein, and maintains a configuration in which permanent magnets are disposed on both sides of the rotor core so as to reduce the weight of the rotor core. A rotor coil can be wound in parallel, and thus, no dedicated winding device is required. Since a number of related parts constituting a motor are small and assembly is simple, the production cost can greatly be reduced. In addition, it is easy to reduce and increase the size of the motor according to the installation location or the part or device to be used, and higher output can be achieved compared to a general motor of the same size. The present invention comprises: a rotor positioned in the axial center direction of a housing to form a magnetic force while a rotating magnetic field is formed; and a stator which is located on the front and rear of the rotor to form a magnetic force, attractive force, and repulsive force of the rotor and which is held by the housing so that the rotor can rotate.
