AC induction motors are not always used in trains as traction engines, however they are a popular choice. AC induction motors are very simple and reliable and aside from bearing wear they have no parts that wear out. This is because the power used by the rotating parts is supplied by the magnetism like in a transformer and so there are no slipping brushes.
Most train systems actually use a DC supply, then a device called an inverter is used to convert the DC to variable frequency to drive the AC motor and control its speed. When this is done the AC induction motor is a very reliable and flexible engine and even allows energy recovery when the train is breaking.
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
why three phase induction motor is delta connected
When you do a load test on a 3-phase induction motor you are checking the power factor, viz slip, and efficiency of the motor. You can test various loads with this test.
Nikola Tesla invented the poly-phase induction motor in 1883.
The direction of a singular phase induction ac motor can be reversed by switching the capacitor in relation with the motor windings. When started in the reverse direction, the motor will maintain the same torque level that it had in the forward direction.
You would use a single-phase induction motor if the available electric power supply is a single-phase one. That applies to the average house or small business.

That indicates a fault in the induction motor.
Yes, that is one of the major advantages of a three-phase induction motor.

Split Phase Induction Motor.
Single phase Induction motor
An electric train uses electric motors. Modern trains have many motors, they are mounted on the axles, one motor per axle. Some axles will be powered and have motors on them, some will not.
single-phase induction motor is used in ceiling fan.
