Winding methods for various motors

The winding methods of electric motors can be classified according to the arrangement and connection of the coils. Here are some common motor winding methods:

Single-phase induction motor winding method: Single-phase induction motor winding methods are usually two types: two-pole winding and four-pole winding. Among them, two-pole winding is to wind the coil on the two magnetic poles of the motor, and the direction of the motor is achieved by changing the direction of the current. Four-pole winding is to wind the coil on the four magnetic poles of the motor, which can increase the speed and efficiency of the motor.

DC motor winding method: DC motor winding methods are usually divided into two types: separate suspension winding and series winding. Separate suspension winding is to wind the coil on the pole of the motor, and connect the coil to the brush separately, and realize the direction of the motor by changing the brush current. Series winding is to divide the coil into multiple sections, then connect them together, and connect the connection point to the brush.

Winding method of three-phase asynchronous motor: The winding method of three-phase asynchronous motor is usually star winding and triangle winding. Among them, star winding is to connect one end of three coils together to form a star, and then connect the other end to the three phases of the power supply. Triangle winding is to connect three coils together in sequence to form a triangle, and then connect the connection points to the three phases of the power supply.

Brushless motor winding method: The winding method of brushless motors is usually to divide the coil into several sections and connect them to the driver or controller separately. Since brushless motors do not require brushes, they can achieve higher speed, more reliable and more precise control, and are widely used in various industrial and mechanical applications.

It should be noted that different motor types and specifications may have different winding methods and parameters, so it is necessary to carefully read the motor specifications and wiring diagrams when selecting and using them, and select the appropriate motor type and parameters according to actual needs.

What is the principle of motor winding?

The motor winding principle is based on the principle of magnetic field generation. The conductor coil is wound around the iron core of the motor. The interaction between the current in the conductor and the magnetic field generates torque to make the motor rotate.

In a motor, the magnetic field is generated by an iron core and a magnetic field excitation source (such as a permanent magnet, armature magnetic field, etc.). When the conductor coil is energized, a current is generated in the conductor, which in turn forms a magnetic field around the conductor. According to the Ampere force, the magnetic field around the conductor coil interacts with the magnetic field of the motor, generating a torque that causes the motor to start rotating.

Motor winding methods are usually classified according to the arrangement and connection of the conductor coils. For example, in a DC motor, the motor can be wound in series or in parallel, while in a three-phase asynchronous motor, the motor can be wound in star or in triangle. These different winding methods and connection methods will affect the performance and working mode of the motor, and need to be selected according to the specific application scenario.

In general, the principle of motor winding is to generate torque through the interaction between the current and magnetic field of the conductor coil to realize the operation of the motor.
