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 Start and Run 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 once the motor has reached operating speed. The capacitors are sized so that both, when connected in parallel, provide optimal starting conditions, while the permanently connected capacitor is sized to ensure good performance during normal operation. Single-phase motors with start and run capacitors and centrifugal switches. The motors are manufactured in accordance with European standard IEC 34-1. The motors are made of aluminum and painted in RAL 9005.
