Motor manufacturers in the product stator winding coil, will strictly execute the coil winding turns according to the motor parameter requirements, for three-phase asynchronous motor and other products, the coil more or less a few laps will cause a certain degree of impact, the following and Senli electric small series together with a simple understanding of it.
The coil of the motor is part of the stator circuit, when energized, ifThree-phase asynchronous motorIf the number of coils is less than the actual, it is equivalent to the reduction of the resistance in the motor stator circuit, then the current will increase, which will cause the magnetic flux density of the motor to increase and saturation, and eventually cause the motor to heat seriously, causing the motor to burn.
From the speed point of view, the number of turns of the coil decreases, the speed of the three-phase asynchronous motor will increase, if it is a hand-wound coil, it will cause the gap between it and the core to increase, which reduces the number of turns of the coil to a certain extent, after the power will be found that the speed of the motor is significantly faster than before, if the number of winding in accordance with the original motor is difficult to insert into the motor stator.
But nowThree-phase asynchronous motor manufacturersThe winding coils are wound by machine, and the process parameters are guaranteed.

Long axis torque motor products, suitable for winding and winding scenarios, can be customized for different industry scenarios, to meet the requirements of use. This product produced by Senli has the characteristics of reasonable structure, high efficiency, good characteristics and long service life.
Shengzhou Senli Motor19Old motor manufacturers, with a number of their own motor production lines, from the shell, shaft, rotor, stator are independent production, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports. From the shaft machining to the whole machine assembly are completed independently. Truly realize factory direct sales.
Senli motor products are used180°High temperature resistance all copper coil material, torque motor products can be used with different rotors (ordinary rotors/Steel rotor), rotor of different motor characteristics are different, we from the shell, shaft, rotor, stator are produced by the independent, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports.
