Motor and preparing method thereof

Abstract

Provided are a motor and a preparing method thereof, wherein the motor enables to enhance the yield rate and the productivity when a structure which arranges a first winding pipe and a second winding pipe in the axial direction is adopted. The first winding pipe (31) comprises a first terminal block (314), which keeps a first terminal pin (11) at one side end in the motor axial (L) direction. The second winding pipe (32) comprises a second terminal block (324), which keeps a second terminal pin (12) to extend to a front end of an arm part of a position adjacent to the first terminal block (314) in the circumferential direction. After a first winding wire (36) is winded on the first winding pipe (31), the end portion of the first winding wire is bound at the first terminal pin (11). After a second winding wire (37) is winded on the second winding pipe (32), the end portion of the second winding wire is bound at the second terminal pin (12). Then the first winding pipe (31) and the second winding pipe (32) are made to be arranged in the motor axial (L) direction.

Description

technical field [0001] The present invention relates to a motor having a first bobbin and a second bobbin arranged in the axial direction of the motor and a manufacturing method of the motor. Background technique [0002] In many motors, a structure is adopted in which a rotor is arranged inside a stator, and in the stator, a first bobbin and a second bobbin on which a coil wire is wound are arranged in a motor axial direction. In the above configuration, it is necessary to separately supply power to the first coil wire wound on the first bobbin and the second coil wire wound on the second bobbin. Therefore, a structure has been proposed in which a terminal block holding a plurality of terminal pins is provided at one end portion of the first bobbin in the motor axis direction, and the end portion of the first coil wire and the end portion of the second bobbin are connected to each other. It is wound to the terminal pin (refer to Patent Document 1). [0003] Patent Documen...

AI Technical Summary

Problems solved by technology

Therefore, there is a problem that the winding operation of the coil wire cannot be effectively performed.

In addition, when a failure such as a disconnection or a short circuit occurs on one of the first bobbin side and the second bobbin side, there is a possibility that the yield is likely to decrease due to failure of the entire stator.
