How are motor capacitors rated?
The battery that keeps your HVAC motor running is called the capacitor. Capacitors are measured through two different ratings. The first is voltage, and the second is microfarads. That means the higher the microfarad rating, the more electrical current it can store.
What is UF rating on a capacitor?
uF refers to the size of the capacitor. Capacitance is the charge that is necessary to raise the potential of a body one unit. A capacitance of 1 farad (f) requires 1 coulomb of electricity to raise its potential 1 volt (v). 1 micro farad (uF) = 0.0000001 F.
What happens if I use a bigger capacitor?
Much the same way, a motor will not run properly with a weak capacitor. This is not to imply bigger is better, because a capacitor that is too large can cause energy consumption to rise. In both instances, be it too large or too small, the life of the motor will be shortened due to overheated motor windings.
What should I look for in a capacitor for an electric motor?
Examine the original capacitor and match its ratings in Voltage and and capacitance, uF or micro farads. Look for and record all of the markings on the capacitor.
What are the ratings of a capacitor battery?
The battery that keeps your HVAC motor running is called the capacitor. Capacitors are measured through two different ratings. The first is voltage, and the second is microfarads. Voltage is the amount of electrical current moving through an electrical system.
What is the capacitance of an AC motor?
These capacitors usually have capacitance values of over 70 µF. They come in various voltage ratings, depending on the application they were intended for. Some single phase AC motor designs use motor run capacitors, which are left connected to the auxiliary coil even after the start capacitor is disconnected by the centrifugal switch.
How to select the correct capacitor for a tun motor?
Capacitance: Select a capacitor with a capacitance value (given in MFD, uf or microfarad) that is equal to the original capacitor. Do not deviate from the original value, as it sets the operational characteristics of the motor. Hz: Select a capacitor with the Hz rating of the original. Nearly all tun vapacitors will be labeled 50/60.
