Auto transformer for a single phase motor starter?

Does a 3 phase motor starter with a 120 volt coil need a neutral to the coil?
Usually for this type of installation there is a control transformer installed in the starter enclosure. The primary of the transformer is the motors line voltage and the secondary is the control voltage which is usually 120 volts. In Canada the control transformer needs fusing on the secondary side of the transformer. In the US the transformer needs fusing on the primary and secondary sides of the transformer. The secondary side of the transformer's terminals are labeled X1 and X2. The X2 lead is grounded to the starter's enclosure. From this point out the wire is then termed the circuit's neutral wire. This wire then connects to one side of the magnetic starters draw in coil. Yes, 120 volt coil would require a neutral, this could be derived from the control transformer if it has one or from an external source.
How do you start a motor without a starter?
By the use of auto transformer and bridge rectifier we can start dc motor.
What is component selection of auto transformer starter?
An Auto transformer motor starter is a device intended to start AC asynchronous motors, instead of connecting the electric motor directly to the electrical grid, it will connect it to the grid in more than just one step. Hence, it will behave as an electro mechanical soft starter. Although it is the "older" method of starting motors, it is still widely used due to its simplicity. The list of parts needed to "make" an "Auto Transformer Motor Starter" is composed from: 1. Auto transformer itself 2. 3 contactor (electrically sized to fit the motor) 3. Two timers, defining when the contactors will "close".
How do you wire a single phase 480 volt starter with a photo cell for lights?
You will not be able to use the line voltage to operate the photocell directly as the photo cell is usually rated for 120 volts or in some instances 240 volts. You will need a step down transformer 480 to 120 volts. The starter will also need to have a 120 volt coil. The black and white wire of the photo cell connects to the output of the transformer and the red wire from the photocell goes to the starter coil. From the neutral terminal of the transformer a wire is taken to the other terminal on the starter coil. The transformer should be about 50 VA.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

What is the function of fans in transformer?
The function of fans in a transformer is to regulate the transformer's temperature.
What is center tap transformer?
Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
