Winding principle of automatic stator coil motor winding machine

The development of motor winding machines has shifted the drive gear to be automated, smart, buyer friendly and diversified. In addition to this, the motor winding work capability has enhanced the productivity and the development of the inductor coil manufacturing industry. Along with the development of manufacturing industry, there is a growing need for motor winding machines and the need to develop and design machines and equipment that are more efficient, environmentally friendly, energy efficient and adaptable.
The working principle of motor stator winding machine: the form and size of motor winding is designed to better fit any specified purpose. The main parameters such as inductor, Q-factor, insulation strength and required magnetic field strength have a very significant impact on the design of inductor coil winding resistance. It is found that inductor coil winding resistance is constructed into various groups regarding the type and geometry of wound inductor coils. Mass production of inductor coils is done only with the help of automated equipment. There are 2 types of motor winding machines for motor winding, which mainly include: stator winding resistance and rotor winding resistance.

The stator winding is divided into 2 types of winding according to the number of magnetic poles of the motor and the number of winding resistance to generate the actual number of magnetic poles in relation to each other, and can be divided into 2 types of apparent pole type and concave pole type.

In the apparent pole type winding, each (group) inductor coil generates 1 pole, and the number of inductor coils (group) of the winding resistor is the same as the number of poles.

2. In the common pole type winding, each (group) inductor coil generates 2 poles, and the number of inductor coils (group) is 1/2 of the number of poles, because the other 50% of the poles are generated by the magnetic force lines of the inductor coils (group) forming the poles together.

Most of the rotor winding resistors are divided into two categories: squirrel-cage type and wire-wound type. The squirrel cage type has a simpler structure, and its winding resistance used to be embedded copper bars, but at this stage most of them are cast aluminum, and the unique double squirrel cage rotor has two sets of squirrel cage bars. Winding type rotor winding resistor and stator winding resistor, also divided into iterative and another waveform winding resistor. The appearance of waveform winding resistors is similar to that of iterative winding resistors, but the wiring method is different. The base element is not a whole inductor coil, but a single-turn unit inductor coil, which is assembled and welded one by one to form an inductor coil group. Waveform winding is usually used for rotor winding of large AC motors or armature winding of medium to large DC motors.
