──Jun 29 , 2021Rotor speed of three-phase asynchronous motor

       Three-phase asynchronous motor manufacturersIn the selection of customers, will say several levels of speed, then many customers are not very clear; Some are marked on the nameplate but do not know how to see this speed, today, Senli Motor Xiaobian will take you to understand the motor speed problem.

       The speed of the motor is calculated by a formula:n=60f/p , of whichnFor motor speed, turn/Minutes;fIs the power supply frequency, in our country50Hz;pFor the motor pole number, two extremely pair, four extremely two pairs and so on. According to this formula we can know a voltage380V, frequency50HZThe number of poles is8theThree-phase asynchronous motor, rotational speed is750r/min.

       And because most commonly used motors areAsynchronous motorIts speed relative to the magnetic field pole changes slightly lag, so the actual speed of the asynchronous motor is slightly lower than the synchronous speed of the magnetic field,2Very generally2960r/minThe quadrupole is generally1450r/minThe six poles are generally960r/minThe eight poles are generally740r/min.

Asynchronous motor manufacturers product picture

       Speed, usually selected according to the load needs. The same power, although the speed is different, the energy transmitted is the same; But there is one thing: the same power of the motor with different speeds, usually, the volume of high speed is relatively small.
