A motor capacitor is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor).
In this topic, you study Capacitor Run Motor – Theory, Construction, Diagram, Working & Torque Speed Characteristic. Capacitor Run motors are commonly called as fan motors. In Capacitor Run Motor, the auxiliary winding (A) along with the capacitor (C) is in the circuit for both, starting and running (Fig. 1).
This hesitation can cause the motor to become noisy, increase energy consumption, cause performance to drop and the motor to overheat. A dual run capacitor supports two electric motors, with both a fan motor and a compressor motor. It saves space by combining two physical capacitors into one case.
There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor). Motor capacitors are used with single-phase electric motors : 11 that are in turn used to drive air conditioners, hot tub / jacuzzi spa pumps, powered gates, large fans or forced-air heat furnaces for example.
Run capacitors are designed for continuous duty while the motor is powered, which is why electrolytic capacitors are avoided, and low-loss polymer capacitors are used. Run capacitors are mostly polypropylene film capacitors (historically: metallised paper capacitors) and are energized the entire time the motor is running.
The shape of the capacitor-motor is a cylindrical hump. In the below circuit, both the L1 & L2 are the two connection points where the electricity supplies throughout these points to both the start & the run coil windings with the start capacitor.
