For an electric motor to be self-starting, a rotating field is required in the motor. In a 3-phase motor this is achieved by the phase shift in the three phases. In a 1-phase motor, an additional winding is required, which is fed with a voltage phase-shifted relative to the voltage across the main winding.
Busck ML, 1-phase electric motors
Depending on the design, motors are divided into different types, for example with a running capacitor (MY) or with a starting and running capacitor (ML).
Busck ML Starting and operating capacitor - high starting torque
In this case, the motor is equipped with two capacitors, one of which is disconnected by a centrifugal switch or a relay when the motor has reached speed. The capacitors are dimensioned so that both in parallel provide optimum starting conditions, while the fixed capacitor is dimensioned for good characteristics in normal operation. 1-phase motors with starting and operating capacitor and centrifugal switch. The motors are manufactured according to European standard IEC 34-1. The motors are in aluminum and painted in color RAL 9005.
