Abstract

The invention discloses a rotating shaft used for a motor. The rotating shaft comprises a main shaft body. The two ends of the main shaft body are an installing end and a fan connecting end respectively. The installing end and the fan connecting end are provided with a key groove. The rotating shaft is characterized in that the shaft center position of the main shaft body is provided with an exhaust pipeline hole. The right port of the exhaust pipeline hole is exposed out of the fan connecting end. The position, which is close to the installing end, of the main shaft body is provided with an air inlet channel communicated with the left port of the exhaust pipeline hole. The main shaft body is provided with an air inducing device corresponding to the channel port of the air inlet channel. The rotating shaft used for the motor has the characteristics of being fast in heat radiation speed and favorable for reducing the use amount of motor iron core silicon steel sheets and motor winding electromagnetic wires.

Description

technical field [0001] The invention belongs to the technical field of motor shafts, in particular to a rotating shaft for a motor. Background technique [0002] Existing motor shafts have poor ventilation and heat dissipation effects, and long-term operation of the motor will cause high temperature inside the motor and the shaft, which will cause failures, reduce the working performance of the motor, and shorten the service life of the motor. Contents of the invention [0003] The object of the present invention is to address the shortcomings of the above-mentioned prior art, and to provide a rotating shaft for a motor, which has the characteristics of fast heat dissipation and is beneficial to reduce the consumption of the silicon steel sheet of the motor core and the magnet wire of the motor winding. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a rotating shaft for a motor, including a main shaft body, the tw...
