(if any). The wiring of a general motor is shown in Figure 2.3: L1 is the running winding,
L2 is the starting winding, C1 is the running capacitor, C2 is the starting capacitor, and
when the motor speed exceeds 75% of the rated speed, the starting capacitor is
switched off through the centrifugal switch K.
