──Aug 11 , 2021Shaft current of motor manufacturer maintenance knowledge solution

       Shengzhou Senli motor mainly produces DC motor, torque motor,Three-phase asynchronous motorBrake motor, single-phase motor and other products, yes3KWBelow the level of small power motor manufacturers, complete products; Special specifications can be customized, available for sample, testable; Today, Senli Motor Xiaobian will share the content of knowledge about motor shaft current for you.

       Let's talk about why the motor produces shaft current. We'llThree-phase asynchronous motorThe shaft of this type of motor product-Bearing block-This current in the base loop is called the shaft current, and the main reasons for the shaft current are as follows5Points:

       (1Magnetic field asymmetry;

       (2There are harmonics in the supply current;

       (3Manufacturing and installation are not good, and the air gap is uneven due to the eccentricity of the rotor;

       (4There is a gap between two semicircles of the detachable stator core;

       (5The number of pieces selected for fan-stacked stator cores is not appropriate.

Three-phase asynchronous motor manufacturers product picture

        The harm of shaft current can cause the bearing surface or ball of the motor to be eroded, and the shape path point microholes will deteriorate the running performance of the bearing, and the friction loss and heat will increase, which will cause the bearing to burn.

       But there are two ways to prevent itThree-phase asynchronous motorThe shaft current of such motor products is generated:

       (1Remove pulsating flux and power harmonics (such as adding an AC reactor to the output side of the inverter);

       (2When the motor is designed, the bearing seat and base of the sliding bearing are insulated, and the outer ring and end cap of the rolling bearing are insulated.

       Shengzhou Senli Motor,3KWAnd the following small power motor manufacturers, support can be providedOEM/ODMCustomization, specification customization, appearance customization, special shaft customization and color customization.
