What Is The Armature Winding of Permanent magnet DC motor for K mechanism?

Apr 19, 2018

The permanent magnet DC motor for K mechanism is a type of permanent magnet DC motor in which the armature windings are connected by a certain number of armature coils in accordance with certain rules. As a circuit part of a DC motor, which is also an electromotive force-inducing electromotive force, a part of an armature winding of a permanent magnet direct current motor that uses electromagnetic torque to perform electromechanical energy conversion is what it is like?


The function of the armature winding in the permanent magnet DC motor for K mechanism is to generate the electromagnetic torque and the induced electromotive force. Since it is a key component of the DC motor for energy conversion, it is called an armature and is formed by connecting many coils according to certain rules.


The coils in the armature windings of the permanent magnet DC motor for K mechanism are wound with high-strength enameled wire or glass wire wrapped with flat copper wire. The coil sides of different coils are embedded in the armature slots on the upper and lower layers, between the coil and the core, and The bottom two coil sides must be properly insulated. In order to prevent the centrifugal force from throwing the coil edge out of the groove, the notch is fixed with a slot wedge, and the terminating portion of the coil extending out of the groove is bandaged with a thermosetting sheer glass tape.


From the perspective of type, the armature winding of the permanent magnet DC motor used in the K mechanism can be divided into two types: self-excited and self-excited, in which the excitation-type excitation winding and the armature winding have no electrical relation. The self-excited type is divided into parallel excitation, series excitation and compound excitation. The parallel excitation is in parallel with the armature winding and the excitation current only accounts for 1%-5% of the rated current.


The series excitation is the two windings in series, the current is the same; the excitation excitation of the compound has two windings, one in parallel with the armature, and one in series. If the magnetic field generated by the series excitation winding and the parallel excitation winding is in the same direction, it is called product complex excitation. If it is the opposite, it is called a compound reward. This is the basic knowledge about the armature winding of a permanent magnet DC motor used in a K-mechanism.
