Abstract

A method for manufacturing an electric motor comprising mounting a plurality of hairpin coils in a plurality of slots, wherein the plurality of hairpin coils includes a first hairpin coil and a second hairpin coil, the first hairpin coil including a first hairpin coil At one end, the second hairpin coil includes a second end. The method further includes inserting the first end and the second end into the space of the conductive connector to electrically connect the first and second ends, and placing an insulating cap over the connector to protect the connector from contact with other conductive materials touch.

Description

technical field [0001] The present invention relates to an electric rotary motor, and more particularly to a method for joining stator winding coils. Background technique [0002] Generally, a motor necessarily includes a stator having coils wound therein and the coils are inserted into slots of the stator. [0003] Recently, demands for downsizing and high efficiency of motors have continuously increased. [0004] In order to achieve miniaturization and high efficiency of the motor according to such demands, the slots of the stator include as many loop coils inserted therein as possible. [0005] However, the number of inserted loop coils is inevitably limited because of a dead space formed between the loop coil and another adjacent loop coil and another dead space formed between the loop coil and the teeth of the stator. [0006] An example of a winding method capable of achieving miniaturization and high efficiency of a motor by solving the dead space problem described ...
