A single-phase induction motor has a main winding and a starting winding. When the motor has run up to normal speed the starting winding can be switched out, but for small motors this is not usually worth the trouble.
What else can I help you with?
Will a single-phase Induction motor run on one winding once it has been started?

How is single phase induction motor is constructed?
An induction motor is an alternating current (only) motor that has one or more coils of wire wound on a metal frame that induces a current in the conductors in the rotor when the rotor is moving at a different than synchronous speed. Synchronous speed it determined by the line frequency and the number of poles the motor has. For example, a two pole motor with a 60 Hz line frequency would have a synchronous speed of 3600 RPM. When used with single phase, the magnetic field generated in the stator needs to be caused to rotate around the rotor. In most cases this is initiated by a separate starting winding that is fed out of phase with the running winding(s). Once the rotor is rotating, the stator's field rotation has been established and the starting circuit is generally switched off.
How do you wire a three phase motor with two speed to a three phase power supply lead numbers not specified?
There are many types of winding on a two speed three phase motor. The number of wires from the motor should have been stated. This is a guess that the motor is a six lead. The diagram is for a six lead out two speed, one winding, single voltage constant horsepower motor.See sources and related link below
What are the Uses of slip rings in motors?
A slip ring motor contains a slip ring, which is a mechanical device that transmits power and electrical signals from a stationary to a rotating structure. They are commonly found in engines used in cable reels, wind turbines, packaging machinery and radio telescopes.
How do you calculate breaker capacity of 10 hp three phase induction motor?
The first thing you have to do is find the full load amps of the motor. The wire size feeding the motor has to be 125% of the full load current. The breaker is usually 250% of the full load current. If the voltage and amperage had been added to the question the exact breaker size could have been calculated.
What is the conclusion of overheat protection of induction motor?
If the overload protection is set correctly to the motors full load amperage, any overloading of the motor will trip the protection and take the motor off line. Once the reason of the overload has been established and rectified, the overload protection is reset and the motor can be brought back on line.
When are Capacitors used with single phase motors?
The capacitor is used to produce a phase shift to create a rotating magnetic field so the motor will start turning. 3-phase motors do not need one because of the phase difference inherent between the phases.While a capacitor connected external to the motor does affect the power factor of the overall system (as mentioned below), an internal start capacitor is not used for that reason in a single-phase motor.Another answerThere is inductive reactance and capacitive reactance. (Look these terms up, it is good stuff). Think of them as opposites in a sense. The operation of the induction motor is inefficient in a power factor sense due to electro magnetic field properties that affect the power factor in an inductive sense. The capacitor is an "offset" to the inductive reactance which, when sized accordingly, affects the power factor as a correction towards unity.
What is meant by slip power recovery scheme?
its about induction motor speed control........
Is Induction Lighting a new technology?
Certainly not Induction Lighting has been around for over 2 decades and the Induction lamp technology has now matured to a first choice lighting solution
How do you switch back on the watch after it been sit and stop working?
It is a traditional watch, you wind it to get it started again. If it is powered by a battery, you replace the battery. If it is self-winding, you move it in the manner designed to make it work.
What is the myelin sheath similar to?
myalin sheath is very similar to the insulation in your motor winding. Only difference is that man is using this insulation from century or two and nature has been using the same since about three billion years.
