Environmentally-friendly noise-reducing insertion shaft servo motor

Abstract

The invention discloses an environmentally-friendly noise-reducing insertion shaft servo motor, and belongs to the technical field of motors. The environmentally-friendly noise-reducing insertion shaft servo motor can achieve the effect that two noise reducing modes of noise absorption and noise insulation are complementary, a noise absorption layer achieves the noise absorption effect by 'combination of activity and inertia' and a noise insulation layer achieves an excellent noise insulation effect by utilizing the medium density difference to weaken the noise generated during the operation of the servo motor from the inside of the motor. At the same time, noise reduction is performed with the noise as the wave nature, the noise wave energy is absorbed by energy absorbing particles, the noise propagation can be greatly weakened, the noise reduction effect of the servo motor is improved significantly, and the noise reduction effect can reach 90%-95%, which is in line with the new environmental protection concept of the society and reduces noise pollution.

Description

technical field [0001] The invention relates to the technical field of electric motors, and more specifically relates to an environment-friendly and noise-reducing interpolation shaft servo motor. Background technique [0002] The motor is a device that converts electrical energy into mechanical energy. It uses the energized coil (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric power rotation torque. The motor uses the power supply Differently divided into DC motors and AC motors, most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the motor stator magnetic field speed and rotor rotation speed do not maintain synchronous speed), and the motor is mainly composed of a stator and a rotor , The direction of the force-moving wire in the magnetic field is related to the direction of the current and the directio...

[0007] 2. Mechanical noise: mainly caused by the rotor and the bearing. The bearing is the connecting member of the rotor and the stator of the motor. It bears the excitation of various forces in the motor and transmits the excitation force, thereby generating vibration and noise. The brushes and slip rings of the motor Or commutator friction can also produce mechanical noise

[0009] The existing servo motors have been optimized in terms of structure or system for the above three types of noise, but no matter what the optimization method is, the generation of noise cannot be avoided. As one of the most common motors, servo motors are often used in various public places , so the noise generated by the servo motor often affects people's normal life or work, and it also poses a threat to the physical and mental health of technicians in a noisy environment for a long time
