[0002] Outer rotor brushless motor refers to a motor with an outer rotor structure and adopts brushless motor control technology to realize a new type of motor. Compared with traditional motors, outer rotor brushless motors have higher performance and efficiency. Outer rotor motors are also commonly used in medical equipment, aerospace and other fields. They are widely popular for their high efficiency, high performance, low noise and low vibration.

[0022] The detector 1 in this article is an external drive device and is a prior art. The detector 1 itself is rectangular, which is convenient for detecting the external rotor 13. In order to better adapt to various types of external rotors 13, a circular detection ring 2 is provided on the surface of the detector 1. The detection ring 2 is fixedly connected to the detection device inside it, and a circular auxiliary body is provided in the middle of the detection ring 2, and the shaft fixing hole 3 is provided in the middle of the auxiliary body, and the shaft fixing hole 3 is adapted to the shaft 14.

The driving mode of the first telescopic arm 4 is an external power supply, which is not clearly marked in this figure, and the first telescopic arm 4 mainly adjusts its telescopic length through the width of the motor 12. The first telescopic arm 4 itself has three sections that can be telescoped. A fixed body is provided on the topmost section. A groove is provided in the fixed body and is connected to the side. A slide groove 6 is also provided at the top to facilitate the sliding of other parts, and a thread is provided in the slide groove 6 to allow other parts to be rotated and fixed.

When the second telescopic arm 5 is not in use, it is telescoped into the groove. The sliding of the second telescopic arm 5 is mainly carried out by the threaded body 7. The threaded body 7 can be regarded as a screw, and a thread adapted to the fixed body is provided on its surface. The threaded body 7 is rotatably connected to the second telescopic arm 5, and the threaded body 7 also determines whether the second telescopic arm 5 slides by rotation. In this way, when the second telescopic arm 5 needs to slide forward, it is only necessary to rotate the threaded body 7 to allow the second telescopic arm 5 to slide, and since the slide groove 6 is of limited length, it can also prevent the second telescopic arm 5 from falling off the groove, thereby improving the stability of the detector 1 to the outer rotor 13, and an attachment 8 for connection is provided at the front end of the second telescopic arm 5, and the attachment 8 is fixed to the second telescopic arm 5 by bolts.
