When install a motor using capacitor for starting or running methods,we must sizing the rated of capacitor suitable with motor to get correct starting torque and avoid winding from overheating and can cause a damage. This is basically a question of motor design.There is no straightforward regular relationship between capacitance and the motor size in […]

Getting the right size capacitor for an electric motor could mean the difference between starting the motor or not. A motor needs a little bit of energy to start the rotation of its metal shaft. A capacitor is used to supply this initial push to the motor. Capacitors store energy and then releases it when the motor ...

Start/run capacitor AC induction motors. Another way to further improve on the single-coil single-phase induction motor design is to introduce an auxiliary coil, which remains powered not only during the motor startup phase, but also during normal operation.

The capacitor size for an AC motor is calculated base on the amount of current required to start the motor. A good rule of thumb is 50 to 100% of the total load.

Start capacitors just give the motor a momentary boot to start I've not found them to be critical as long as the size is reasonable,I'd try the one from the 3/4 hp motor.Or buy one at a motor shop for a 1/2 hp motor. Frank C.

Start capacitors I try to never undersize and in some situations it can be advantageous to oversize the start capacitor. The drawbacks to incorrect capacitor size. On a permanent split phase capacitor motor if the capacitor is too small the motor will never come up to speed, to large capacitor and you can burn out the windings in the motor. If ...

Run vs. Starting Capacitor. Single phase electric motors use a device called a starting capacitor to create a large phase shift to produce necessary torque during start up. Single phase motors will commonly have both a run capacitor and a starting capacitor. Starting capacitors differ from run capacitors by their relative capacitance value being much higher for a given physical size.

An air conditioner that is not working on a hot summer day is very annoying and even potentially dangerous. If you are able to determine that the compressor can be repaired by replacing the capacitor, it is a simple process to fix it. However, you need to make sure that you have the correct capacitor size.
