Motor start capacitors are rated with two main values. One is capacitance in micro farads and the other is in voltage.
Motors that use capacitors are single-phase AC motors. The capacitor is used to "start-and-run" the motor. The capacitor is wired between the incoming hot service wire and the "start-and-run" terminal of the motor. The other terminal of the motor is connected to the outgoing neutral service wire. These capacitors are designed to run on AC (two DC capacitors back-to-back) so It doesn't make a difference which way round the two terminals are wired. If the case is metal it is usually grounded to the ground wire. Some motor "start and run" capacitors are plastic-cased so don't need any ground wire.
Power factor capacitors can be installed on a three phase motor between the motor contactor and the overload heater block.
Since you have the drawing it would be good if you connect the capacitors according to the drawings. I am saying this since you might end up swaping the start and run capacitors although the run capacitor is usually smaller then the start. However this swapping can be advantageous since it mean slightly increased running talk for the motor.
No, they are two different concepts. The start capacitor is used in conjuction with a starting winding on a single-phase induction motor to produce a small component of rotating field inside the motor. This ensures it rotates the desired way. The run capacitor is used to correct the power-factor of the motor, which reduces the current drawn from the supply for the same amount of power.
The voltage rating for a start capacitor must be at equal to the motors line voltage or greater.The formula used to find the value of a motor starting capacitor is 2650 X FLA/VAC = mfd.See related link below, page 462 to 465 for full details about motor capacitors
The capacitors used in table fans is to start its induction motor.

Capacitors are rated in Microfarads
Motor start capacitors, also known as electrolytic motor start capacitors, provide a quick and reliable way to start an electric motor. They are an effective power-current delivery system that, when combined with a motor, helps to provide the power required to start a motorized device. Motor capacitors are unique in that they are able to deliver a large amount of current in a short amount of time, which is something that is not possible with a conventional battery. When a motor is switched on, it takes a moment for the motor to reach its operating speed. Visit here : falconcapacitor. com
There are 2 types of capacitor including starting capacitor and running capacitor running capacitor are used to improve the power factor of motor. starting capacitor used in split phase induction motor . starting capacitor may isolate from motor,s starting winding through of centrifugal switch after getting motor 90% of it,s rated speed.

Start capacitors and run capacitors are two different types of capacitors. They alter the current to create a rotating magnetic field. They have two or three terminals to which the wires are attached.
Connect your start capacitor in series with the start winding.Connect the run capacitor in the common terminal and Line 1 of the power supply.

A capacitor add torque to an electric motor that is designed to use them, they are called PSC or permanent split capacitor type motors. the capacitors terminals go to the Run and Start windings.
