Description
Technical Field
The invention belongs to the field of bearing application, and particularly relates to an integrated shaft for a motor.
Background
The motor heat dissipation body system on current unmanned aerial vehicle is perfect inadequately, and the radiating effect is not good enough, is unfavorable for motor efficient operation, and the long-time use of motor, and structural design is also reasonable inadequately. The motor can produce a large amount of heats at long-time operation in-process, if the heat distributes away in not timely from the motor, the motor will continue to operate under high temperature, is unfavorable for the motor to rotate high-efficiently this moment, also is fairly unfavorable to the use of motor moreover, the life of the motor that has significantly reduced. The bottom of current motor bearing upper cover is provided with the arch that outwards extends on one side and dispels the heat, but can only guarantee that the fan just can play the radiating effect when rotatory to a fixed direction, can't satisfy two-way rotatory needs. In the prior art, the S-shaped radiating fins are difficult to form in a machining process, and fine deviation can be generated in a secondary machining process in a machining process on a lathe, so that the problem of deviation generated by unmanned maneuvering balance is caused.
