The stator winding of a dynamic motor is the coil structure mounted on the stator of the motor to generate a magnetic field and drive the motor. It is one of the key components of the motor.


CONSTRUCTION: The stator winding of a dynamic motor consists of wires or coils, usually wrapped in insulating material to prevent short circuits or insulation breakdown. The conductors are usually round copper or aluminum wires, and depending on the design and requirements of the motor, the wires can be wound in single or multiple layers on the stator slots or raised cores.

Turns: The number of turns of the stator winding refers to the number of turns of the coil wound on the stator. The choice of the number of turns usually depends on the rated voltage, power and conditions of use of the motor. An increase in the number of turns increases the output power and torque of the motor, but also increases resistance and current losses.

Number of Phases: The number of phases in the stator windings of a moving motor depends on the design of the motor and the requirements of the application. Common phase numbers include single-phase, two-phase and three-phase. Single-phase motors are suitable for low-power applications, while three-phase motors are typically used in high-power applications because they offer better starting performance and smooth operation.

Connection: The connection of the stator windings of a moving motor determines how the coils are connected to each other. Common connections include star (Y-connection) and delta (Δ-connection). Star connection is suitable for three-phase motors and provides higher current capacity and lower current leakage, while delta connection is suitable for high-torque applications.

 Insulation: The wires of the stator windings need to be insulated to prevent short circuits between the wires or between the wires and the stator core. Commonly used insulation materials include insulating varnish, insulating paper and insulating tape.

Slot shape: stator windings are usually wound in the stator slot, the slot shape has an important impact on the way of winding and winding process. Slot shape selection consider the diameter of the wire, winding density, heat dissipation and insulation and other factors.

The stator winding of a dynamic motor is a very important part of the motor, which generates a magnetic field that interacts with the rotor magnetic field to realize the rotation of the motor. The design and manufacturing quality of the stator winding is directly related to the performance, efficiency and reliability of the motor. Therefore, the parameters, materials and processes of the stator winding need to be carefully considered during the design and manufacture of the motor in order to meet the requirements of the motor and to improve the performance of the motor.
