When the three-phase asynchronous motor manufacturer produces this motor, it is composed of two parts: a fixed stator and a rotating rotor. The rotor is installed in the inner cavity of the stator, and is supported on the two end caps with the help of bearings, which is to ensure that the rotor can rotate freely in the stator. Here is a small series with Senli motor to understand the rotation principle.

The torque motor has the characteristics of low torque at high speed and high torque at low speed. When winding starts, the load is small and the action is fast. At the end of winding, the load increases, and the low speed output high torque. This motor produced by Senli Motor meets the rewinding requirements.

The rolling paper we use in daily life is a very important process in production. When the diameter of the coil gradually increases, it is very important to achieve constant tension in the production process. Senli Motor is a torque motor manufacturer, and the characteristics of the products produced fully meet this requirement.

Cascade speed regulation is actually to change the slip rate of three-phase asynchronous motor by changing the rotor resistance, so as to change the speed and achieve the purpose of speed regulation. When the slip rate s of the motor increases, along with the speed decrease, the working point moves down, and the mechanical characteristics become soft.

Torque motor manufacturers are also in order to facilitate memory when marking the model, taking Senli motor model YLJ90-4-3.0 as an example: YLJ indicates the series code, 90 indicates the frame number (the frame number is common with the national standard), 4 table pole number, and 3.0 table lock-torque. From this motor model, we can see what the parameters of the motor are.

Pole change speed regulation is a method to change the pole number of three-phase asynchronous motor by changing the connection of the stator winding to achieve speed regulation. Or first look at the formula N=60*f/P, changing the pole is to achieve the effect of speed regulation by changing the value of P; We can see from the formula that if P is smaller, then it will be higher relative to N. Changing the number of magnetic poles of the motor can change the speed of the motor.

Compared with ordinary motors, the parameters that need to be considered in the design of AC variable frequency motors are overload capacity, starting performance, efficiency and power factors, which are also widely used in life. Below, follow Senli Motor Xiaobian to understand its working principle.

Under the same load by artificial way to change the speed of the motor, we will call this is speed regulation. Today, the three-phase asynchronous motor manufacturer Senli Motor Xiaobian will take you to understand how to speed regulate the motor and what are the ways.

Torque motor is a special motor with more poles designed to reduce the speed without changing the output torque; When the power supply voltage is reduced, the motor speed decreases, but the output torque and current are unchanged. Today, follow Senli Motor Xiaobian to understand the mechanical characteristics of this motor.

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.
