In the case of the loss of the nameplate, if you want to know the number of three-phase asynchronous motor poles used, we can use the current μA of the multimeter to test and judge, and the following is a simple understanding of Senli Motor Xiaobian, how to use the multimeter to judge the number of poles of the asynchronous motor.

When selecting the torque motor, it is mainly the matching of its speed, the speed conference causes energy waste, and the speed is small without moving the mechanical operation, so we need to select the torque motor speed according to the requirements of the production machinery, and ensure that the motor matches the speed of the equipment when purchasing.

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 biggest reason why ordinary motors cannot be used as variable frequency motors is that when the motor runs at a low frequency, the speed is relatively slow, the ordinary motor tail fan and the motor rotor use a concentric shaft, the motor speed is slow, and the fan blade speed is also slow, the wind is small, and is not conducive to the heat dissipation of the motor.

Want to achieve single-phase asynchronous motor anyway, in fact, and double capacitors have nothing to do, capacitors with larger capacity are starting capacitors, which are automatically opened by the off-core switch after starting, and capacitors with smaller capacity are running capacitors, which are connected in series at one end of the secondary winding, and always move together with the secondary winding. Below and Senli motor Xiaobian together with a simple understanding of the next.

Electromagnetic brake is a commonly used additional device of brake motor, there are two kinds of power-on brake and power-off brake. The former can achieve a rapid positioning effect, the latter can ensure that in the event of an unexpected power failure, the equipment can be safely braked in a state of runaway, and the following is a small series of Senli motor together to understand it.

Single-phase asynchronous motor refers to the asynchronous motor using single-phase alternating current, which has the advantages of simple structure and low noise. Because of its use, it only needs to use single-phase power supply, which is more convenient to use, and is used in industry and life, the following is a simple understanding with Senli Motor Xiaobian.

If the connection of the three-phase asynchronous motor is star-shaped, then the actual voltage is that the phase voltage is 220v, and if it is angular, the line voltage is 380v, and the phase voltage is obviously lower than the line voltage. Here is a small series with Senli motor to understand the next.

YEJ series brake motor is a fully enclosed self-fan-subcooled squirrel-cage type three-phase asynchronous motor with additional disc DC brake. It has the advantages of fast braking, simple structure, high reliability and strong versatility. In addition, the brake has a manual release mechanism, which is widely used in a variety of mechanical equipment and transmission devices requiring rapid stop and accurate positioning.

Three-phase asynchronous motor speed formula n=60f/p, in which changing the power supply frequency f, motor pole number p can achieve the purpose of changing the speed, from the nature of speed regulation, different speed regulation is nothing more than to change the synchronous speed of the AC motor or do not change the synchronous rotation two.

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.
