What is multi speed motor?
Some electric motors have windings enabling them to run at different speeds.
How star delta helping motor from overheat?
star delta motors start as a Y for 3 phase so the windings that normally see 480 volts see 277V a relay switches to delta then it runs as a normal delta motor the reduces the starting current by about 60% for 3 phase
How many windings are in universal motor?
one windingAnswerA three-phase motor has three phase windings, normally (but not necessarily) connected in delta.
What are motor made from?
an electric motor is a copper winding or 3 separate windings depending on the phase, the copper winding is the centralised inside of a iron magnet, this is also how a generator is made instead of putting a current on you turn the windings to receive a voltage .
The motor starts in star but does not run in delta?
Whenever you start a big heavy electric motor, you need to start it slowly to prevent the rotor overheating and drawing an enormous current or to prevent damage to the load it is driving. When the windings of a 3-phase motor are connected in STAR the current is reduced by a factor of (one over root three) times (the normal running current that is taken when it is connected in DELTA.)Once the motor picks up speed, the connection is changed to DELTA so that the motor runs at full speed and torque from then on. It's a bit like using the gears of an automobile.For more information, see the answers to the Related Questions shown below.
What is the reason if you are running an electric motor with a star delta starter but whenever it is switched to delta at the same instant its circuit breaker trips?
Check your Delta connections first if the phases is corresponding, and check your Circuit Breaker if it sufficiently rated.
How does a star winding shifts to a delta winding in a three phase motor?
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.
What is multi speed motor?

What is the function of armature winding?
The winding function of an electric motor is a description of how the number of conductors in the windings around the motor changes with position.

Should a star-delta motor be supplied wye or delta power?
A star-delta motor should be supplied star-delta.Wye is simply another name for star. Star-delta motors use a star or wye configuration to start, and a delta configuration to run. This reduces the voltage on the windings during the high current starting time.
The windings of an AC motor are called?
Windings
What happens to an electric motor if it overheats?
The windings melt. Also may start a fire if surround conditions permit.
How many windings are in universal motor?

Why is a 3 phase induction motor phased out before use?
In order to identfy the motor windings so that it may be used in both star and delta connections according to its ratting current
What size of electric motor that requires wye delta starter?
10 hp and above motor power rating....
