Motor start and motor run capacitors start capacitors.

Motor capacitor guide. Therefore you can select a capacitor with a voltage rating at or above the original capacitor. Motor starting capacitor motor run capacitor dual run capacitors and hard start capacitors used on electric motors such as air conditioner heat pump compressors fan motors some well pumps some heating equipment motors. If youre using a 370 volt capacitor a 370 or 440 volt one will work though the 440 volt unit will actually last longer.

In the capacitor start motor capacitor c is of large value such that the motor will give high starting torque. Capacitor employed is short time duty rating. You may hear it humming or observe that its getting hot.

This intermittent duty capacitor is only energized when the motor first starts. Types of electric motor start run capacitors. You may be able to cross reference the cat number to narrow down the parts.

Currently this website is under development with the goal to be as good as a reference on capacitors as the resistor guide is on resistors. It helps increase the starting torque of the motor and allows it to be cycled on and off rapidly. If the capacitor has failed the symptom is that the motor wont start.

The capacitor guide will guide you in the world of resistors. These capacitors usually have capacitance values of over 70 uf. This article explains and gives an identification guide to types of electric motor capacitors.

Start capacitors are used on capacitor start motors. This article explains how to choose buy an electric motor start capacitor hard start capacitor or run capacitor that is properly rated for and matches the requirements of the electric motor such as an ac compressor motor or fan motor where the capacitor is to be installed. Once you locate your motor part number follow the row across to find your run capacitor start capacitor bearings etc.

Search the motor part number to see if you can locate the cat number. Electric motor starting run capacitor troubleshooting faqs questions answers about electric motor start boost or run capacitors capacitors are electric devices that get an electric motor running at start up or that help keep a motor running once it has started. When install a motor using capacitor for starting or running methodswe must sizing the rated of capacitor suitable with motor to get correct starting torque and avoid winding from overheating and can cause a damage.

A capacitor will have a marked voltage indicating its acceptable peak voltage not its operational voltage. Motor start capacitors are used during the motor startup phase and are disconnected from the circuit once the rotor reaches a predetermined speed which is usually about 75 of the maximum speed for that motor type. Capacitor employed is short time duty rating.
