Abstract

The invention discloses a motor which comprises a mounting seat, a stator fixed to the mounting seat, a rotor rotating relative to the stator and a rotary shaft connected with the rotor. The stator comprises at least one pair of coil leads, the motor further comprises a protection structure fixed to the mounting seat and / or the stator, and the protection structure is used for preventing the rotor or the stator from being in direct contact with the coil leads. The motor is provided with the protection structure protecting the coil leads of the stator, the coil leads are prevented from being abraded, and therefore the performance of the motor is guaranteed.

Description

【Technical field】 [0001] The invention relates to the technical field of aircraft power devices, in particular to a motor. 【Background technique】 [0002] With the development of new permanent magnet materials, microelectronics technology, automatic control technology and power electronics technology, motors have made great progress. The motor uses electronic commutation to replace the traditional mechanical commutation. With its advantages of reliable performance, no wear, low failure rate, small size and high efficiency, it has gradually developed from the initial military field to the aerospace field. [0003] The aircraft is capable of vertical take-off and landing, stable hovering and autonomous cruising, and is suitable for police surveillance, news photography, fire command, traffic management, geological disaster investigation and pipeline cruising to realize real-time mobile surveillance in the air. At present, the power of the aircraft is realized in the form of a...
