    How to calculate the slip of an asynchronous motor?

    The most direct feature of asynchronous motors is that there is a difference between the actual speed of the motor and the speed of the magnetic field, that is, there is a slip; compared with other performance parameters of the motor, the slip of the motor is the easiest to obtain, and any motor ...

  • Is there a difference in the speed of the asynchronous motor in different states?

    Is there a difference in the speed of the asynchronous motor in different states?

    Slip is a specific performance parameter of an asynchronous motor. The current and electromotive force of the rotor part of the asynchronous motor are generated due to the induction with the stator, so the asynchronous motor is also called an induction motor. To evaluate the speed of an asynchron...

    How to measure the basic parameters of the motor?

    When we get a motor in our hands, if we want to tame it, we need to know its basic parameters. These basic parameters will be used in 2, 3, 6, and 10 in the figure below. As for why these parameters are used, we will explain in detail when we start to pull the formula. I have to say that I hate ...

    what does PTO mean

    pto stands for power take off . PTO is a switch control method, mainly used for speed and position control. It is the abbreviation of PTO pulse train output, interpreted as pulse train output. The main function of PTO is to obtain power from the vehicle chassis system, and then through its own co...

    How to predict motor performance from rotor turning condition?

    Rotor turning is a necessary process in the production and processing of electric motors. During the turning process, it should be ensured that the rotor punches cannot be displaced or rewound in the circumferential direction, especially for rotors with windings. Because of the displacement of th...
