Chute low-noise motor

Abstract

The invention relates to a motor, in particular to a chute low-noise motor, which comprises a machine seat, a stator, a rotor and a rotating shaft, wherein the stator, the rotor and the rotating shaft are arranged on the machine seat, the rotor comprises at least two sections of rotor iron cores, the rotor iron cores are punched and laminated by a false axis inclination angle taper key method to form chute iron cores; chutes of the adjacent chute iron cores are in opposite directions and are in arrangement in a way of staggering for an angle alpha. Therefore, the chute low-noise motor has the following advantages that 1, great-degree optimization is respectively realized in aspects of vibration, noise, iron core laminating quality, cast aluminum quality and chute cast aluminum rotor structure adopted by a high-power motor, and the chute low-noise motor is suitable for small and medium-sized cast aluminum rotor structure alternating current motors with higher vibration and noise requirements; 2, the stress uniformity and the rigidity of iron core laminating punching are fundamentally ensured, the iron core laminating quality is improved, the influence of deformation on vibration noise is reduced, the aluminum overflowing and bubble problems are solved, and the quality of the cast aluminum rotor and the motor performance reliability are improved.

Description

technical field [0001] The invention relates to a motor, in particular to a chute low-noise motor. Background technique [0002] The vibration and noise of motors have attracted more and more attention and attention, especially in some special occasions, such as the field of military ships, the vibration of motors (structure noise machine foot acceleration) is more stringent. The motor chute is widely used because it can effectively weaken the harmonics of the weak teeth of the motor and the magnitude of the harmonic magnetomotive force, and reduce vibration and noise. Usually, most motors use a single chute structure, but the single chute structure is prone to axial force Axial series movement and torsional vibration are caused; there are also literatures that propose a double chute "herringbone" structure (similar to the present invention), but there are uneven lamination stresses of punching sheets, complex aluminum casting molds and difficult guarantee of aluminum castin...

Problems solved by technology

The motor chute is widely used because it can effectively weaken the harmonics of the weak teeth of the motor and the magnitude of the harmonic magnetomotive force, and reduce vibration and noise. Usually, most motors use a single chute structure, but the single chute structure is prone to axial force Axial series movement and torsional vibration are caused; there are also literatures that propose a double chute "herringbone" structure (similar to the present invention), but there are uneven lamination stresses of punching sheets, complex aluminum casting molds and difficult guarantee of aluminum casting quality. There are even more problems in the structure of high-power cast aluminum rotors
