To check a 220/240 volt single-phase capacitor start motor, first ensure the power is off to prevent electrical shock. Use a multimeter to measure the resistance across the motor windings; a significant difference or an open circuit can indicate a fault. Next, inspect the start capacitor by checking for continuity and measuring its capacitance with a capacitor tester. If the capacitor is faulty, it may need to be replaced before further testing the motor.
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
fan is a capacitor start capacitor run single phase induction motor. since single phase induction motors are not self starters, caused by discontinuty in stator mmf. so to iniate rotation single phase supply is splitted 90 degree apart by a capacitor to convert it to a 2 phase motor, which produces a continued synchronously revolving mmf in stator to start the motor. cool !!
See Discuss Question below.
Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
capacitor start motor
Very often a capacitor IS used in a single-phase motor. It provides a phase-shifted current to the starting winding to ensure that the motor runs in the right direction, e.g. clockwise if that is the requirement.
A run capacitor is used to improve the efficiency and power factor of a single-phase motor by providing a phase shift to the auxiliary winding. Once the motor is running, the capacitor helps maintain a steady motor speed and performance. It remains in the circuit to assist in the motor's operation.

Some examples of single-phase motors include split-phase, capacitor-start, shaded pole, and permanent split capacitor (PSC) motors. Each type has its own unique design and application, offering different characteristics and performance capabilities.
The capacitor is used to create a second phase from the single phase power source and it is the interaction between these two phases that causes the motor to turn.

to start the motor and give more current to motor to run
mainly due to undervoltage.
