In the motor selection, we need to select according to the rated speed of the equipment, and we need to consider the transmission ratio of the mechanical delay mechanism, so today, Senli Motor Xiaobian will take you to understand the selection of voltage and speed of the three-phase asynchronous motor.

       Usually, we're choosingThree-phase asynchronous motorWhen the rotational speed is not less than500rpmBecause at constant power, the lower the motor speed, the larger the size, the more expensive the price, and the lower the efficiency. If a high-speed motor is chosen, a mechanical delay mechanism will be unavoidable. The transmission ratio complicates the mechanical transmission part.

       For some high-speed and medium-speed machines that do not require speed regulation, such as pumps, blowers, air compressors, etc., a motor with the appropriate speed can be used for direct transmission without mechanical delay mechanisms.

       For machines that require speed control,Three-phase asynchronous motorThe maximum speed should be compatible with the speed of the production machine. The intermittent cycle working machine that requires fast and frequent starting and braking can achieve the fastest starting and braking effect, usually when the moment of inertia of the asynchronous motor rotor is the lowest product of the square of the rated speed.
