The motor that can stop working quickly after the motor is powered off is called the brake motor, also known as the brake motor. It is a kind of machine that can stop in the movement process to achieve a precise positioning effect. Today, Senli Motor editor will take you to a simple understanding of the precautions for YEJ electromagnetic brake motor operation.

The temperature rise is a very important performance indicator for the motor, and the temperature rise is the temperature difference between the three-phase asynchronous motor and the environment, which is caused by the motor heating. In operation, the iron core of the motor in the alternating magnetic field will produce iron loss, the winding will produce copper loss, and other stray loss. These will increase the temperature of the motor.

The main role of the insulation material is to isolate the conductors in different parts of the motor, so that the current can flow in a predetermined direction, and the insulation material is also a relatively weak link in the three-phase asynchronous motor, and many failures occur in the insulation part. Below and Senli motor Xiaobian together to understand it.

The temperature rise of the motor generally refers to the temperature of the three-phase asynchronous motor in the rated operating state, the temperature of the motor stator winding is higher than the ambient temperature value, generally speaking, the ambient temperature is specified as 35℃-40℃ below, if the nameplate is not marked with the specific value, the default is 40℃.

Induction motor lead wire heating causes as well as the material and cleaning problems of the terminal, the unreasonable structure of the terminal board, we first say the former, for the induction motor lead terminal, its responsibility is very important, not only need to bear the fixed lead wire and the terminal board, but also need to have good electrical conductivity.

Motor low-voltage operation will also lead to heating problems, when the asynchronous motor is in a state of low-voltage operation for a long time, the current will be greatly increased, and the lead wire will need to withstand a larger current, especially some of the lead wire diameter of the choice is not very large, the larger current density will directly lead to the three-phase asynchronous motor lead wire heating.

Motor wiring is an important part of the motor products, in general, if the induction motor wiring is selected in accordance with the current density of the specification, there will be no heating problem, but in the actual production, there will be such problems from time to time, today, Senli Motor Xiaobian will take you to a simple understanding.

Autumn October, harvest season. Warmly celebrate Shengzhou Senli motor exceeded the production and sales performance target, both successful. All the employees of the company work together, exert the same force, grasp the management inside, expand the market outside, take technology as the cutting edge, take quality as the guarantee, promote the work safely and orderly, and exceed the production and operation targets from July to August 2021.

The no-load current of the small motor can reach 60% of the rated current, or even higher; However, the no-load current of the large motor is only about 25% of the rated current; The no-load current and rated current of the three-phase asynchronous motor are related to the power of the motor, below we simply understand.

In the operation of the three-phase asynchronous motor, the lack of phase can be said to be a more common situation, if the long-term operation in the lack of phase state, will lead to motor failure, affect the operation of the equipment, serious motor will burn. The following Senli motor Xiaobian will take you to understand the next.
