Problems solved by technology

[0002] For the stator of the external rotor motor, it is basically insulated by surface coating, which causes the stator to be wound from the teeth of other phases, which increases the length of the winding and correspondingly lengthens Increase the length of the winding, increase the resistance and the amount of copper used, so increase the copper loss and reduce the efficiency of the motor
In addition, due to the increase in the amount of copper used, the cost of the motor will also increase accordingly

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0022] Such as Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a winding frame, the upper surface of the winding frame is provided with more than two winding slots, and the openings at both ends of each winding slot are located on the side walls of the winding frame .

[0023] There are two or more winding slots on the winding frame, so that the winding wires of each phase pass through the winding frame, avoiding the wires from the teeth, which can effectively solve the problem of winding wire passing, and can solve the problem of The problem of increased motor resistance and copper loss is solved, the efficiency of the motor is effectively improved, and the cost of the motor is reduced.

[0024] The winding skeleton in the embodiment of the present i...

Abstract

The invention discloses a winding frame and an outer rotor motor provided with the winding frame. More than two winding slots are arranged on the upper surface of the winding frame, and the openings at both ends of each winding slot are located at the center of the winding frame. on the side wall. Applying the technical solution of the present invention, two or more winding slots are provided on the winding frame, so that the winding wires of each phase pass through the winding frame, avoiding the wires from the teeth, and can effectively solve the problem of winding overshoot. The problem of wires can be solved, and the problem of increased motor resistance and copper loss can be solved, the efficiency of the motor can be effectively improved, and the cost of the motor can be reduced.

Description

technical field [0001] The invention relates to the field of external rotor motors, in particular to a winding frame and an external rotor motor with the winding frame. Background technique [0002] For the stator of the external rotor motor, it is basically insulated by surface coating, which causes the stator to be wound from the teeth of other phases, which increases the length of the winding and correspondingly lengthens The length of the winding is increased, the resistance and the amount of copper used are increased, so the copper loss is increased and the efficiency of the motor is reduced. In addition, due to the increase in the amount of copper used, the cost of the motor is correspondingly increased. Contents of the invention [0003] Embodiments of the present invention provide a winding skeleton and an outer rotor motor having the winding skeleton, so as to achieve the purpose of improving the efficiency of the motor and reducing the cost of the motor. [000...
