15KB30 is a type of three-phase asynchronous motor with a rated output of 0.75-150KW and a rated voltage of 380V. It is widely used in general industrial machinery, agricultural machinery, machine tools, pumps, fans, conveyors, printing presses, mining machinery, as well as food machinery, medical equipment, etc. It is mainly used in places with unstable power supply.

The 15KB30 is alsoknown as an asynchronous motors. Asynchronous motors are divided into two types: squirrel cage motors and wound rotor motors according to the rotor structure. The 15KB30 is a squirrel cage type, which is relatively simplified in structure. It consists of driving wheel and rotor, stator body, motor head cover, bearing and so on.

The working principle of 15KB30 is as follows: a three-phase alternating current is connected tothe stator windings of the motor, and a rotating magnetic field is generated in the air gap between the stator and the rotor. The rotor of 15KB30 is an aluminum alloy squirrel cage type. The rotor has slots on the surface of the iron core, and copper bars are buried in the slots. When the rotating magnetic field cuts the stator current and the rotor conductor, an electromagnetic induction force is generated in the conductor, and a current is induced in the conductor. The interaction between the magnetic field and the current supplies the rotor with torque. Under the action of the electromagnetic torque, the rotor rotates, thus forming a closed loop.

As a type of three-phase asynchronous motor, 15KB30 has advantages such as high efficiency, large starting torque, small volume, light weight, reliable operation, easy maintenance, etc. In addition, it is easy to control speed by changing the frequency. Therefore, it is widely used in general industrial machinery, agricultural machinery, machine tools, pumps, fans and other fields.
