Description

Technical Field

[0001] The utility model relates to the field of direct current motors, in particular to a voltage-equalizing wire installation structure for direct current motors. Background Art

[0002] There are two types of voltage equalizing wires: Type A and Type B. Type A voltage equalizing wires are used for single-fold windings, and their function is to improve the asymmetry of the motor's magnetic field. Type B voltage equalizing wires are used for compound wave windings, and their function is to ensure that the currents in each parallel branch of the winding are equal. In single-fold windings, the magnetic flux asymmetry caused by various reasons leads to unequal induced electromotive forces in each branch. When unloaded, a large circulating current is generated inside the armature winding; when loaded, the current distribution of each branch is seriously unbalanced. Therefore, in each branch, the points with equal potential on the armature winding are connected with wires. This connecting line is called Type A voltage equalizing wire. In compound wave windings, the equipotential points between the two independent closed loops in the double closed-circuit compound wave winding are connected to eliminate the influence of uneven brush contact resistance. This equipotential connecting line is called Type B voltage equalizing wire.

[0003] In the prior art, when installing the voltage equalizing wire on the commutator of a DC motor, the process is cumbersome and complicated, and the workers are time-consuming and laborious when operating. At the same time, the commutator is usually installed on the rotating assembly by bolt locking. After installing the voltage equalizing wire, multiple bolts need to be removed, which not only increases the difficulty of disassembly and replacement, but also reduces the overall installation efficiency.
