An internal floating vibration isolation motor

Abstract

The invention discloses an internal floating high-efficiency vibration-isolation motor. The high-efficiency vibration-isolation motor includes a casing and a base. A rotor shaft, a rotor, and a stator are arranged inside the casing from the inside to the outside. The rotor shaft is provided with at least Two sets of polarizing rings, at least two sets of polarizing rings make the rotor and stator concentric, the base is provided with a vibration isolation plate, and the vibration isolation plate is fixed to the casing. The invention reduces the vibration from the inside of the motor through the polarization ring, and reduces the influence of the external vibration on the motor through the base. The invention isolates the vibration of the motor from the external and internal factors at the same time, and has the effect of high-efficiency vibration isolation.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an internal floating vibration isolation motor. Background technique [0002] Motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its main function is to convert electrical energy into mechanical energy, generate drive torque, and use it as a power source for electrical appliances or various machines. [0003] At present, there will be noise after the motor is started. The main sound sources of the motor noise include electromagnetic noise, air duct noise and mechanical noise, and the mechanical noise is mainly due to the noise generated by the vibration of the bearing. [0004] We know that noise and vibration are integrated with each other, and vibration will inevitably cause noise, and the mechanical reasons for motor vibration include: [0005] 1. The feet are not fastened firmly, and the fo...
