Sound insulation and noise reduction type motor

Abstract

The invention discloses a sound insulation and noise reduction type motor. The motor comprises a base, a motor shell is fixedly connected to the upper surface of the base, a heat dissipation plate isfixedly connected to the outer surface of the motor shell, a mounting bottom plate is fixedly connected to the outer surface of the heat dissipation plate, a noise reduction layer is fixedly connectedto the outer surface of the mounting bottom plate, a noise reduction layer is fixedly connected to the outer surface of the noise reduction layer, and a protection plate is fixedly connected to the outer surface of the noise reduction layer. According to the sound insulation and noise reduction type motor, the effect of carrying out multi-stage filtering and noise reduction on the noise generatedby the motor is achieved, the noise reduction layer firstly performs primary noise reduction on the noise generated by the motor, a part of noise is absorbed in advance by the sound-absorbing spongein the sound-absorbing device, and then secondary noise reduction is carried out under the blocking of inert gas in the sound insulation layer, finally, repeated refraction is carried out under the refraction effect of a refraction plate in the sound insulation layer, and finally noise reduction is carried out to the maximum extent, so that the problems that the loss frequency and the maintenancecost of a motor used in a forging workshop are very high are solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a sound-insulating and noise-reducing motor. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. [0003] The motor is represented by the letter M (the old standard is D) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function The function is to convert electrical energy into machinery. [0004] At present, the motors used in the forging workshop will produce large noise due to vibration after long-term use, and because there are more dust and oil in the forging workshop, compared with other motors used in relatively clean environments, the motors used in the forging workshop The use and loss will be greatly advanced, an...
