in a delta configuration the current is split between the phases, as opposed to a wye configuration where the current will be equal on all phases.
and vice versa for voltage.
Some electric motors have windings enabling them to run at different speeds.
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
one windingAnswerA three-phase motor has three phase windings, normally (but not necessarily) connected in delta.
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 .
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.
The Stator, the Rotor and the Windings.
Check your Delta connections first if the phases is corresponding, and check your Circuit Breaker if it sufficiently rated.

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.

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 melt. Also may start a fire if surround conditions permit.
