Mute motor structure convenient to install

Abstract

The invention relates to the technical field of micromotors, in particular to a mute motor structure convenient to install. The structure comprises a motor shell, a magnetic shoe is arranged in the motor shell; a motor rotating shaft is arranged in the middle of the motor shell; a rotor is arranged on the rotating shaft of the motor, an armature winding is wound on the rotor; a commutator is connected with the rotor, an end cover is arranged at one end of the motor shell; the two sides of the end cover are respectively provided with carbon brush arms and a power connection terminal. A conductive terminal is arranged at the tops of the carbon brush arms; a screw is connected between the conductive terminal and the carbon brush arms; one end of each carbon brush arm is suspended and is provided with a carbon brush, an installation guide angle used for insertion of a commutator is formed between the two carbon brush arms, an accommodating cavity used for accommodating a capacitor is arranged in the end cover, an accommodating seat used for accommodating the commutator is arranged in the middle of the end cover, and a sealing cover plate is arranged at the bottom of the end cover. Themute motor structure is compact in structure, ingenious in design and flexible and convenient to install, the structural stability is improved, and a good silencing effect and stable working performance are achieved.

Description

technical field [0001] The invention relates to the technical field of micro-motors, in particular to an easy-to-install silent motor structure. Background technique [0002] Micro-motor, the full name of "micro-motor", micro-motor is often used in the control system or transmission mechanical load, for the detection of electromechanical signals or energy, analytical calculation, amplification, execution or conversion and other functions, in the micro-motor, the carbon brush through The elastic carbon brush arm is installed on the end cover of the motor, and the carbon brush is in frictional contact with the commutator of the rotor under the elastic force of the carbon brush arm. Electrically connected, the external power supply supplies power to the armature winding of the rotor through the conductive terminal, carbon brush arm, carbon brush, and commutator in turn. When the existing micro-motor is running, the rotor and surrounding parts such as commutator and carbon brus...

AI Technical Summary

Problems solved by technology

When the existing micro-motor is running, the rotor and surrounding parts such as commutator and carbon brush arm may slightly vibrate due to the high-speed operation of the rotor, which will reduce the structural stability and generate mechanical noise, which will not only greatly It affects the connection stability and normal operation of the internal parts of the micro-motor, and also causes a certain degree of noise pollution. At present, a mute box is generally used to insert the micro-motor for isolation treatment. Although it can achieve a certain mute effect, However, the mute box is a fixed installation structure. The existing micro-motor has a complex structure and is not easy to install. Therefore, it is not convenient to open the mute box to operate and maintain the micro-motor. The mute effect is not good, and the working performance of the micro-motor is reduced.
