Shengzhou Senli Motor, the main products include: DC motor, torque motor, three-phase asynchronous motor, brake motor, single-phase asynchronous motor, etc.;

We go on to the last part, the last part we talked about in order to overload the three-phase asynchronous motor, the heat generated to reach the limit temperature, to ensure that the motor winding is not burned, it is necessary to let the motor stop working, we will call this protection overheating protection, today Senli Motor Xiaobao continue to take you to understand about overheating protection measures.

Choosing a three-phase asynchronous motor with power matching the equipment can be said to be a problem that many equipment manufacturers often worry about when choosing, if you want the motor efficiency to be good, the power selection must be suitable, then today the Senli motor editor will take you to understand how to choose a three-phase asynchronous motor with power matching.

The motor is the power provider of the mechanical equipment in operation, and there will be some problems in the use process, such as heating phenomenon, inability to start, etc., and the application range of the three-phase asynchronous motor is very wide, so today, Senli Motor Xiaobian will take you to understand the reasons for the heating of the three-phase asynchronous motor.

We often talk about the number of motor poles are 2-3000r /min, 4-1500r /min, 6-1000r /min, etc., and these are called synchronous speed, but in fact, each model of three-phase asynchronous motor in actual operation, its speed is different, will be lower than the synchronous speed, Today, Senli Motor Xiaobian will take you to understand.

The previous article said that the motor itself has four problems: winding break, winding short circuit, connection error and mechanical failure, and we have already understood the winding break and short circuit of the three-phase asynchronous motor, and today the Senli motor editor will summarize the motor overheating phenomenon caused by wiring errors and mechanical failures.

The previous several articles talk about the power supply problems, load problems caused by the cause of motor overheating, and load problems can not be ignored, we choose or install three-phase asynchronous motor before, because of the manufacturer to confirm, but also to check the nameplate power is consistent with the required power, today, Senforce motor small edition from the motor itself existing problems, for everyone.

Because the environment used by the three-phase asynchronous motor is different, like some outdoor use environment, the motor is easy to water, then whether the water motor can still be used? Senli Motor Xiaobian tells you here that the general motor will not be broken because of water, but the insulation will be greatly reduced.

The first two articles we around the power supply problem, of course, three-phase asynchronous motor overcurrent causes more than the content mentioned in the article, like the power supply of Senli motor Xiaobian is only about the voltage is too high or too low, line asymmetry, three-phase imbalance, today Senli motor Xiaobian starting from the motor load, for everyone to summarize.

In the previous part, we talked about the three-phase asynchronous motor voltage is too high or too low, it is easy to cause the winding copper loss to increase, resulting in motor heating, Senli motor small series mainly from the power supply problem, load problem, there are problems, these three directions, for everyone to simply summarize the reasons for the three-phase asynchronous motor overcurrent, today is still around the power supply problems.
