Armature Winding Of DC Motor

As the circuit part of the DC motor, the armature winding plays a vital role in the whole equipment. Different classifications meet different voltage and current requirements. Their main difference lies in the appearance of the brush, the armature winding. The connection is a different number of parallel branches, of which the single-stack winding and the single-wave winding are two basic types. The following small series will take everyone to understand its classification:

(1) Stacked winding: refers to two components connected in series, the connection method is that the terminating portion of the latter component is folded over the previous component ending portion, and the entire winding is folded forward. Stack windings are divided into single stack and cascade windings. The number of brushes is equal to the number of poles of the motor. Half of them are positive brush sets and the other half are negative brush sets. The number of parallel branches of the stacked winding is large, which is equal to the number of poles or an integral multiple of the number of poles, so it is also called parallel winding.

(2) Wave winding: The wave winding of a DC motor refers to a series of corresponding components under a magnetic field of the same polarity separated by a pair of pole pitches, like a wave forward. Wave windings are further divided into single wave and complex wave windings.

(3) Hybrid winding: A DC armature winding formed by mixing a suitably matched stack winding and wave winding. The coils of the stacked windings and the wave windings are connected in parallel on the same commutator. This type of winding acts as a equalizing line between the wave winding coil and the winding winding coil, so there is no need to additionally add a equalizing line.

According to the different connection methods, the armature windings of the DC motor are divided into three categories, each of which has its own characteristics and advantages, and the use conditions are also different. When selecting the armature winding, it must be based on the actual situation and Rated voltage and current to better reflect the superior performance of the device.
