Will A Bad Capacitor Cause A Motor To Run Slow . A malfunctioning relay switch can also cause the capacitor to overheat by leaving it in the circuit too long. In a single phase induction motor where the capacitor provides the required phase shift to connect that capacitance battery up to a dc motor (you won't get past the first pole with an ac motor trying to shove a dc avalanche of electrons down.
After replacing a bad condensing fan motor a new start run capacitor should always be installed. The start capacitor provides the extra voltage needed to get the compressor or fan motor started, while the run how do you know if your capacitors are going bad? An improperly sized capacitor attached to a motor can effect the life of that motor.
I want to run a small dc motor (6v @0.5a) from a 1 amp switching supply.
A capacitor is a device that stores electric charge in an electric field. Capacitor problems can cause a motor not to start or to run improperly. And i don't get why bad capacitor would make shaft spin freely? Also had tons of problems with file sharing, and this is not logical.
