Description

High-speed motor with anti-drop insulating rotor connecting end Technical Field The utility model relates to the field of high-speed motors, in particular to a high-speed motor with an anti-drop insulating rotor connecting end. Background Because a gap is required to be reserved between the stator and the rotor when the motor is assembled, the gap is required to be increased in order to meet the requirement of the mounting sleeve, fundamental wave and higher harmonic components exist in the gap, and the conversion efficiency of the whole energy is greatly reduced due to the existence of the harmonic waves for the rotating motor. For rotating motors, harmonic currents or voltages create additional losses in the stator windings, rotor loops, and core, resulting in reduced overall energy conversion efficiency of the motor. Through searching, in the prior art, chinese patent publication No. CN207732574U discloses a high-speed motor, which comprises a stator, a rotor, a casing and a sleeve arranged between the stator and the rotor, wherein the sleeve is fixed on the casing, and is characterized in that a metal film is also arranged on the sleeve. The utility model inserts the sleeve into the slot on the shell, can better fix the sleeve, make the sleeve firm on the shell, avoid the sleeve from producing the position deviation because of vibration, raise the overall energy conversion efficiency of the high-speed motor, but still have the following defects: (1) The existing motor rotor assembly is arranged in the rotor body in an interference connection mode, and stress exceeds the supporting force of the interference connection in the process of high-speed rotation of the rotor, so that the rotor assembly is loosened, and the stability of the rotor assembly is affected; (2) The existing motor rotor cannot provide assistance to air flow, and air resistance can be increased during rotation, so that the rotation stability effect is affected.
