After the motor is started with the reversing switch in 1 position, it will turn one particular way. It’s also important to see that the operating states of the motor may also affect surrounding temperature. In the event the motor is the sole electrical device which is to be powered then we can concentrate on the price of replacing the motor with one of precisely the same specifications, but by means of the available power at the place where the machine is going to be installed. As always, consult with the wiring diagram on the specific motor you’re using.
A great deal of motors will have a number of excess wires coming off the windings. In the event the motor doesn’t have a wiring diagram, start with the starting winding lead that’s on the capacitor or centrifugal switch. This sort of motor can be adapted for use for a servo motor, described elsewhere within this chapter. There are a few motors which use a huge capacitor for starting and a more compact capacitor for continuous operation.
Reversing the motor is just a matter of moving the power connection so the other winding is directly on AC. Typically, it will be a 6-lead or 9-lead motor. In either case, it will need to be replaced. Contemporary AC induction motors are rather easy to wire as alternating current generators, and most will get started generating electricity the very first time you use them.
