Noise-reduction small and special motor

Abstract

The invention discloses a noise reduction small and special electric machine, which comprises a machine body, a rotor and a second screen plate, the rotor is installed on the inner wall of the machine body, the rotor is rotatably connected with the second screen plate through a bearing, the outer wall of the second screen plate is fixedly connected with the inner wall of the machine body, and a sound insulation mechanism is arranged in the machine body. The sound insulation mechanism comprises an inner cavity, a wood-wool sound-absorbing board layer, a mineral wool sound-absorbing board layer and a polyester fiber sound-absorbing board layer, the inner cavity is formed in the machine body, and the inner wall of the inner cavity is connected with the wood-wool sound-absorbing board layer in a sleeved mode. According to the noise-reduction small and special motor, the inner cavity of the machine body is filled with a wood-wool sound-absorbing plate layer, a mineral wool sound-absorbing plate layer and a polyester fiber sound-absorbing plate layer in the sound insulation mechanism, so that when the machine body operates, the noise-reduction characteristic of the wood-wool sound-absorbing plate layer, the mineral wool sound-absorbing plate layer and the polyester fiber sound-absorbing plate layer is utilized; and therefore, noise generated when the machine body works can be effectively reduced, and noise pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a noise reduction micro-motor. Background technique [0002] Micro motor, the full name of micro special motor, referred to as micro motor, refers to the micro motor with a diameter less than 160mm or rated power or with special performance and special purpose. Functions such as solving, amplifying, executing or converting, or used to drive mechanical loads, can also be used as AC and DC power sources for equipment. [0003] Although the existing micro-motors can realize the functions of detecting, solving, amplifying, executing or converting electromechanical signals or energy, or used to drive mechanical loads, and can also be used as AC and DC power sources for equipment, the existing micro-motors When the motor is working, it will generate noise, spread the noise, and cause noise pollution, which is inconvenient. SUMMARY OF THE INVENTION [0004] The purpose of the present...
