より、安全性と原価低減を計るものである。After inserting the fixed core 3 into the stator frame 2 of the electric motor to the specified position, the stator winding 4 is inserted by an insertion machine.The shape of the coil end of the inserted stator winding is as follows.
Since the insulation distance between the stator frame and the coil end is in an unshaped state, it is difficult to maintain the specified dimension as the diameter of the motor becomes smaller. Therefore, the coil end protection cap 1 of the present invention is fixed. Insert into the inner diameter of the child frame, that is, between the stator frame and the coil end. The coil end protection cap of the present invention is a coil end protection cap molded from an elastic and insulating material such as resin, so that the insulation between the stator frame and the coil end is ensured. In addition, the several protrusions A installed on the outer diameter of the coil end protection cap are fitted into the air holes B installed in the stator frame to prevent them from coming off, which eliminates the conventional thread tying process. It is possible to reduce the number of processes. In addition, the coil end storage portion Q of the coil end protection cap is shaped according to the volume of the coil end, so that the coil end can be shaped without unreasonable shaping. Furthermore, in order to strengthen the insulation, varnish is injected through the varnish injection hole d installed on the side surface of the coil end protective cap. Further, since the coil end protection cap is deeply inserted into the inner diameter side D, safety can be ensured without contacting and damaging the rotor 6 when assembling the motor and the inner diameter part of the coil end when inserted. Therefore, due to the regulation of the L dimension of the coil end protection cap, etc.
The goal is not only to downsize the motor, but also to reduce the number of steps and ensure insulation, thereby increasing safety and reducing costs.
