A chute low noise motor

Abstract

The invention relates to a motor, in particular to a chute low-noise motor, which includes a machine base, a stator arranged on the machine base, a rotor and a rotating shaft; the rotor includes at least two sections of rotor cores, and the rotor cores The oblique key method of false shaft inclination is used to laminate the punched sheets to form a chute core; the chute of adjacent chute cores is in the opposite direction and the angle is staggered? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? set up. Therefore, the present invention has the following advantages: 1. The vibration and noise, the quality of iron core lamination, the quality of cast aluminum, and the structure of the cast aluminum rotor with inclined slots for high-power motors are all optimized to a large extent, and are suitable for vibration and noise requirements. High, the motor type is a small and medium-sized cast aluminum rotor structure AC motor; 2. It fundamentally ensures the force uniformity and rigidity of the iron core laminated sheet, improves the quality of the iron core laminate, and reduces the deformation and vibration noise The impact of aluminum spillage and air bubbles is solved, and the quality of the cast aluminum rotor and the reliability of the motor performance 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
