Run Capacitor Vs Start

The run capacitor in your ac is used to store energy which is used to turn the fan motor an essential component to your working ac. In contrast the start capacitor specifically provides the energy needed to start up your air conditioner.

This capacitor contains a higher capacitance than a run capacitor.

Run capacitor vs start. As you might expect it takes more torque to start the motor than to keep it running so the capacitance that is the energy storage capacity of a start capacitor must be higher than that of a run capacitor. Start capacitors ratings of 70 microfarad or higher have three voltage classifications. The start capacitor generally has more capacitance than a run capacitor the 7 to 9 microfarad capacitor which continues to improve the motors performance after it has begun running.

Run capacitors are more commonly used in air conditioning systems than start capacitors. Motor run capacitors will then operate after the circuit is started. The start capacitor provides an immediate electrical push to get the motor rotation started.

Examples would be a 35 uf at 370v run capacitor and an 88108 uf at 250v start capacitor. The run capacitor uses the charge of the dielectric material that separates the two plates of the capacitor to provide more current to the motor. Check out this video.

125v 250v and 330v. They are energized while the motor is in operation. Run capacitors are more common.

Motor run capacitors are designed for continuous duty. Httpsyoutubeidrmyuthggm subscribe for free swimming pool care and maintenance videos eve. It varies but a start capacitor will measure between 70 and 120 micro farads.

They store the energy that is needed to keep the fan motor going so that the air conditioner continues to cool down your house. A start capacitor is found in the circuit of start windings when the motor is starting. Without the run capacitor the fan cannot turn.

Looking for a new start or run capacitor. 2 starting capacitors are housed in a black plastic case and have uf range as opposed to a specific uf rating on run capacitors. Using a motor run capacitor will run the motor with greater efficiency.
