In production, the commonly used three-phase AC, if there is no special requirements, generally use AC motor, mainly because the three-phase AC asynchronous motor has a simple structure, robust and durable, and reliable work, easy maintenance, but also has the disadvantage that the speed is more difficult, so we are often used for mechanical characteristics of hard and no special requirements of the general production machinery drag.

The brake motor can realize fast braking after power failure, and can also change the wiring according to customer needs to achieve slow braking effect. YEJ series products have reliable braking performance and low noise, which are widely used in production. The principle is that when the motor is powered off, the electromagnet is powered off, and the armature is immediately subjected to the resistance of the spring, so that the brake disc and the rear end cover of the motor are pressed together to stop rotating.

Compared with the general motor, the torque motor has the characteristic of maintaining constant tension, which is called constant torque characteristic. Torque can usually remain basically unchanged in a large speed range, which is suitable for the transmission situation that requires constant torque when the speed changes, so it is widely used in textile, printing, rubber and other industrial fields.

We know that the three-phase asynchronous motor has slip rate, the rotor speed is smaller than that of the stator rotating magnetic field; The speed of the motor and the frequency of the power supply, the number of poles is directly related to the synchronous motor, whether in the no-load or load state, its speed is consistent with the rotating magnetic field speed.

We commonly use electromagnetic brake as an additional device on the brake motor; In form, there are two kinds of power-on braking and power-off braking. Power-on braking can be quickly positioned and accurately positioned, but the application has certain limitations; Power-off braking is easy to control and fast braking speed. Power-off braking means that the equipment can brake safely when the power failure is out of control, ensuring the safety of people and facilities.

YEJ series electromagnetic brake motor, suitable for frequent start, load holding, emergency braking, accurate positioning of all kinds of machinery, is one of the motor products; It has the characteristics of compact, fast braking, reliable operation, etc. It is widely used in automatic packaging machinery, reducer and so on. Here is a simple understanding with Senli Motor Xiaobian.

There are many forms of motor protection measures, different protection measures corresponding to different uses, to the common overload protection, for example, in the three-phase asynchronous motor auxiliary failure, if the long-term over-fixed current operation, it will lead to overheating, insulation reduction will lead to burn. Here is a simple understanding with Senli Motor Xiaobian.

In the selection of motor products, many equipment manufacturers often worry when choosing supporting equipment, because how to choose a suitable power of three-phase asynchronous motor, the following is a simple understanding with Senli Motor Xiaobian.

Efficiency and power, as important parameters of motor products, are often used as the basis for selection; So in the three-phase asynchronous motor products, what is the relationship between the two? Here is a simple understanding with Senli Motor Xiaobian.

YS series three-phase asynchronous motor is widely used in general agricultural and industrial and mining enterprises to drive the slip rate and other performance of the machinery without special requirements, because of its good starting performance, will also be used in some of the starting torque has higher requirements. Here is a simple understanding with Senli Motor Xiaobian!
