If a capacitor is directly connected across a motor then the capacitance of the capacitor will be calculated as under.
Q = 0.9 * Sqrt (3) * V * I0.
Here "V" = Supply voltage & I0 = No Load Current of Motor.
AnswerThere is no need to connect capacitors across a three-phase motor.

How you determine the starting and running winding of a capacitor start single phase motor?

What is run capacitor in single phase motor starter with three wire?
A run capacitor and a starter capacitor are not the same thing. A run capacitor is energized the entire time the motor is running, and a start capacitor is not. A run capacitor is one that changes the current on the windings of a single phase AC induction motor to create a rotating magnetic field to energize a second-phase winding. A start capacitor increases starting torque, allowing a motor to be turned on rapidly. It stays in the circuit only long enough to bring the motor to 3/4 of full speed. Some motors then continue to run with a run capacitor.
What are the types of single phase ac motor?
capacitor start motor
Why is a capacitor NOT used in a single phase 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.
Why can a run capacitor with a single phase motor remain in circuit after the motor starts?
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.

What are four types of single phase motors?
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.
Why do you connect a capacitor with an Ac motor?
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.
How single-phase induction motor classified?
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.
What motor is used for lathe spindle?
Single phase induction motor ( usually capacitor- start type)
Why do you use codenser in fan?
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 !!
What s the role of capacitor in a single phase induction motor?
to start the motor and give more current to motor to run
Cause of single phase capacitor start motor burning?
mainly due to undervoltage.
