Description

Motor commutator connecting structure

Technical Field

The utility model relates to a commutator technical field, in particular to motor commutator connection structure.

Background

The motor is an electromagnetic device for realizing electric energy conversion or transmission according to an electromagnetic induction law. Denoted in the circuit by the letter M (old standard by D). Its main function is to generate driving torque as power source of electric appliance or various machines. A commutator is also called a "commutator". An important component on dc motors and ac commutator motor armatures. The cylindrical or disk shape is formed by a plurality of copper sheets separated by mica sheets, and each copper sheet is connected with some armature winding elements. When the armature rotates, the copper sheets are successively contacted with the fixed brushes. In a dc motor, ac power in an armature winding is converted into dc power between brushes via the brushes and a commutator.

The motor rotates due to the force between the poles, and in order to maintain the motor rotating continuously, a commutator is used to change the direction of the poles of the motor. When the motor is connected with the commutator, a connecting structure is usually used for realizing the installation of the motor and the commutator.

However, the existing commutator of the motor has two problems, one is that the angle problem is neglected when the commutator is assembled, so that the assembled motor has the difference between the positive and negative rotating speed and the output rotating torque, and the motor performance is not consistent; secondly, in the process of high-speed rotation, the commutator segment on the commutator is easy to loosen because of being unstable in fixation, thereby influencing the performance and stability of the motor.

For example, chinese patent publication No. CN211579815U discloses a connection structure of a motor rotor commutator, the relative angle between a hook on a commutator segment and an adjacent rotor chip is controlled in the range of (180-3N)/N ~ (180 + 3n)/N, the difference between the positive and negative rotation speed and the positive and negative rotation torque can be effectively adjusted, a protruding block is arranged at one end of the commutator segment far away from the rotor core, a butt portion is arranged at the corresponding position of the protruding block in the accommodating groove, and the problem that the commutator segment on the commutator is not fixed and is not firm and is easy to loosen is effectively solved by abutting the protruding block and the butt portion.

Although the fixing firmness of the commutator segment on the commutator is increased by the connecting structure, when the commutator is used for a long time, the larger force can be borne between the steering segment on the commutator and the connecting structure, the commutator is required to be lubricated, and the structure does not have a self-lubricating structure, so that the commutator can be worn and torn, the using effect of the commutator is influenced, and the practicability is low.
