When we test the insulation between turns of three-phase asynchronous motor products, we should pay attention to the test in the no-load state, and the following is a simple understanding of the method of insulation test between turns with Senli Motor Xiaobian.

Industrial and agricultural machinery involves a wide range of scenes, with the development of modern science and technology, many manufacturers began to use frequency conversion motor + inverter AC speed regulation, because of its better performance and urgency, in the field of speed regulation, led a replacement of the traditional way of speed change, the following Senforce motor Xiaobao will take you together with a simple understanding of it!

Now the frequency conversion motor speed regulation on the market, generally using frequency converter for speed regulation, today, Senli Motor Xiaobian mainly take you to understand the topic of bearing insulation, the following and Senli motor Xiaobian requirements for a simple understanding.

In the short-circuit test, we need to control the rotor with brakable equipment, so that the rotor of the three-phase asynchronous motor is fixed, and then the output voltage of the three-phase voltage regulator is gradually increased from zero. When the current reaches the rated current of the motor, the boost voltage is stopped, and the voltage is called the short-circuit voltage.

Our company is committed to the development and manufacturing of high-efficiency motor products, the main products are three-phase asynchronous motor, torque motor, brake motor, single-phase asynchronous motor, DC brushless motor and other series. It can provide the overall customized solution of the motor for the major enterprises.

When we use single-phase asynchronous motor products, we should pay attention to whether the speed in the operation process is normal, whether it can start normally, how the temperature rise state is too high, and whether there is vibration and noise in the operation of the single-phase motor, because the single-phase asynchronous motor is powered by single-phase AC. Therefore, compared with three-phase asynchronous motors, it is more prone to failure problems such as failure to start or abnormal speed.

Motor energy saving is a problem that we will pay attention to in daily production, three-phase asynchronous motor product is a more used in our production, with high efficiency, stable operation, good starting performance and other advantages, and want a product in the production and application of energy saving, the main thing is reasonable selection.

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.
