Abstract

The invention discloses a permanent magnet motor employing a PCB winding. A PCB structure is adopted by the winding of the motor; in order to reduce eddy-current loss under the condition of a relatively high current of the winding of the motor, on one hand, a single wide winding conductor in a main magnetic field is converted into a plurality of narrow winding conductors in parallel; and on the other hand, a single wide end part conductor at one end part is at least converted into a plurality of narrow end part conductors in parallel; parallel branches of two parts are the same in number; and the parallel branches of the two parts are connected one by one in series. According to the permanent magnet motor employing the PCB winding, the eddy current loss of the PCB winding is greatly suppressed; additional moment generated by an eddy current is reduced; the motor output is improved; and the permanent magnet motor has important significance in energy conservation and improvement of the efficiency of the motor. A rigid PCB and a flexible PCB can be adopted by the PCB winding disclosed by the invention; and the permanent magnet motor can be applied to an axial-flux motor, a radial-flux motor, a rotary motor or a linear motor and the like.

Description

technical field [0001] The invention relates to the field of motors, in particular to a permanent magnet motor using PCB windings. Background technique [0002] In the existing common permanent magnet motor, the windings are mostly placed in the iron core slot and wound along the teeth of the motor iron core. However, for several types of motors such as coreless permanent magnet synchronous motors, ironless permanent magnet linear motors and slotless permanent disk motors, the winding of motor windings is more difficult and the process is complicated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple permanent magnet motor using PCB windings for the defects of motor winding processes such as coreless permanent magnet synchronous motors, coreless permanent magnet linear motors and slotless permanent disk motors. motor. [0004] In order to solve the above technical problems, the present invention provides...
