Title: METHOD FOR IMPROVING THE CHARACTERISTICS OF SYNCHRONOUS AND ASYNCHRONOUS MOTORS
Abstract:
The invention relates to a method for improving the characteristics of electric motors. The technical result is a smooth startup of the drive shaft and limiting the startup current and the maximum current. In the claimed invention, a rotor is characterised by the presence of a differential coupling in the body thereof which enables the rotor to rotate at various speeds relative to the drive shaft according to the load on the drive shaft. The rotor is combined with the differential coupling described in the invention in that the rotor body is divided into two main parts, called the rotor head and rotor core. During operation of the electric motor, the rotor head interacts with the stator magnetic field, rotates and creates torque. This torque is transferred to the rotor core, which is disposed in the rotor head and is fixedly connected to the shaft.
