I cannot be 100% certain that the centrifugal switch on my table-saw motor is bad, but here are some symptoms that I recently experienced:
1) The motor starts fine, but the motor-start capacitor...
In a single phase electric motor, the centrifugal switch allows the start winding to be energized through the start capacitor when the motor is starting. This gives an out of phase magnetic field...
AC stands for alternating current, and DC is direct current. A motor is a device that uses electrical energy to spin. An AC motor uses AC voltage, and a DC motor uses DC voltage....
In dc motors, the electric power is conducted directly to the armature (i.e., rotating part) through brushes & commutator. Hence, in this sense a dc motor can be called as a Conduction motor....
