Variable frequency speed regulation is a speed regulation method that changes the speed by changing the frequency of the stator power supply of the motor. Generally, the use of frequency converter for speed regulation of three-phase asynchronous motors is also very characteristic, and the following is a simple understanding of Senli Motor Xiaobian together!

In the nameplate of the three-phase asynchronous motor, various parameters are generally marked, such as model, power, insulation level, current, connection, etc., then what is the insulation level of the three-phase asynchronous motor? Here is a simple understanding with Senli Motor Xiaobian.

Senli Motor, 20 years focus on the development and production of motor. The main products include three-phase asynchronous motor, torque motor, brake motor, single-phase asynchronous motor, variable frequency motor, DC motor and other products. Contact number: 0575-8378-1127.

Is the speed of three-phase asynchronous motor the same under no-load and load conditions? We know that the motor speed is related to the power supply frequency and the number of motor poles, and the rotor speed of the asynchronous motor will be smaller than the rotating magnetic field speed of the stator, that is, there is slip. Then then with Senli motor Xiaobian simple understanding.

Torque motor produces heating phenomenon, a large part of the reason is that in the selection, the selected output torque is not enough, too small output torque is used on the larger load equipment, it is very easy to cause heating phenomenon, then the following is a simple understanding with Senli Xiaobian.

We know that the voltage is too high, too low or asymmetric voltage will increase the current, so that the motor heat and damage the motor. So what causes the torque motor to heat? The following Senli Xiaobian and you have a simple understanding.

Was there any current imbalance in the three-phase induction motor during the test? In order to prevent unqualified products from leaving the factory, DC resistance is generally measured after winding wiring, and three-phase no-load current balance test is carried out during the inspection test.

We know that if the motor is aluminum wire, then the performance level of this three-phase asynchronous motor product is difficult to achieve more specified efficiency levels, and can not achieve high efficiency performance requirements, then you know how to distinguish between copper wire and aluminum wire? The following and Senli motor Xiaobian together to understand it!

When we receive the torque motor products from the manufacturer, do not work directly on the machine, before installation, we need to check whether the motor is deformed or damaged during transportation, whether the rotor is flexible by hand, whether the nameplate parameters meet the order requirements, etc., then the following is a simple understanding with Senforce Motor Xiaobian.

Three-phase asynchronous motor is also known as induction motor, it is an AC motor by the air gap rotating magnetic field and the rotor winding induction current interaction to produce electromagnetic torque, so as to achieve the conversion of electromechanical energy into mechanical energy. Here is a simple understanding of the characteristics of the next three-phase asynchronous motor with Senli Motor Xiaobian.
