A damaged or burnt out capacitor may hold only a fraction of the energy needed for the. This article describes a c electrical motor troubleshooting. Electric motor test repair guide. This one shows how to repair the start switch on the centrifugal start motor.
Place the ends of the wires on the opposite side from the brushes onto the ac motor terminals. The higher the capacitance of the capacitor the more energy it can store. The magnets repel the electrical energy and force the armature in the motor to rotate. A bad motor capacitor may cause starting problems or could shut off the motor while running.
You can service wiring connections bearings and. Replace the screws into the screw holes and then tighten them using a screwdriver. Motor capacitors store electrical energy for the motor to use. I cover the symptoms and how to fix three of the most common motor problems for dc and ac motors found in power tools and appliances.
Replace coil if you get a high reading indicating an open circuit and that the coil is defective. Capacitor start electric motors use a starting coil and a capacitor to create an advancing magnetic field in the stator outer frame of the motor with its coils. This advancing magnetic field gives the rotor something to chase causing the rotor to spin. Electricity is passed to the windings in the armature via carbon brushes.
