The two windings are in parallel with each other. Some motors have a capacitor placed between the two windings. Other connections find a switch between the two windings. When the motor gets up to speed, the switch opens and the start winding is taken out of the circuit and the motor runs on the run winding.
Potential relays are used to energize the start winding of split-phase motors when the motor is starting up. They help provide the initial burst of power needed to get the motor running, and then de-energize once the motor is up to speed.
To shift from a star winding to a delta winding in a three-phase motor, the connections between the windings need to be rearranged. In a star winding, the ends of the windings are connected to a common point (neutral), while in a delta winding, each winding end is connected to the start of the next winding. By physically switching the connections, the motor can be reconfigured from star to delta winding.
Yes if it's a dc motor with a permanent magnet field, or if it's a 3-phase ac motor. No if it's a single-phase ac motor or a dc motor with a field winding in series or parallel with the armature. <<>> Single phase AC motors can be reversed by using a reversing switch. Reverse either the start winding or the run winding connections but not both.
A single phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.
With the starting winding disconneted the motor will start up in whichever direction it is spun. To make the starting winding operate the other way, it needs an inductor in series insead of a capacitor. Details depend on the motor, but the reactance of the inductor should match that of the capacitor.
Potential relays are used to energize the start winding of split-phase motors when the motor is starting up. They help provide the initial burst of power needed to get the motor running, and then de-energize once the motor is up to speed.
Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.
I think the resistance value of starting winding is less than the running winding of the single phase motor
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.

Single phase motor will not start automatically unless it has a start and run winding.
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 that, along with the in phase magnetic field from the run winding, helps the rotor to begin spinning. Once the rotor reaches a certain speed, the centrifugal switch changes state and cuts off the start winding. At that point, the motor continues running only through its run winding, and inertia keeps the rotor properly phase biased relative to the run winding's magnetic field.
No, commutator motors as used in vaccum cleaners for example do not use a starting winding. Single-phase induction motors need a starting winding without which they will start in either direction if given an initial twist.
Its a servo.

The run winding of a single phase capacitor start motor has a lower resistance than the start winding.
