Abstract:
1. A method of making a ball joint universal rotary motor, comprising: magnetizing a spherical-cap shaped permanent magnet into a plurality of magnetic poles to form a stator body; manufacturing a rotor body by cutting silicon steel plate material into multiple silicon steel laminations with varying diameters, and stacking multiple silicon steel laminations to form multiple layers of armatures; connecting the multiple layers of armatures by a bolt passing through the armatures and spacer layers, wherein a spacer layers is provided between two adjacent layers of armatures; winding a first layer of coils on a rotor core of each layer of armature, wherein the first layer of coils is wound on the same layer of armature; winding a second layer of coils on a rotor core of each layer of armature, wherein the second layer of coils of one layer of armature is configured to be electrically connected with another second layer of coils on another layer of armature that is symmetrically distributed in equal distance from a center of the rotor body with respect to the one layer of armature; securing the rotor body within the stator body.
