How do you start a three phase motor to a single phase power supply?
You don't. A three phase motor will not start unless it is connected to a three phase supply.
What happend when you start motor without starter?
The windings of the motor will be gonebecause of high current diectly goes to the windings of motor.
How do you start single phase induction motor?
capacitive start motors start by themselves however a normal single phase induction motor requires a starter motor to 'kick-start' the motor into action.
Drawing block diagram of single phase capacitor start motor?
Drawing block diagram of single phase capasitor start motor?
What are the types of single phase ac motor?
capacitor start motor
How do you connect a single phase motor containing 4 wire leads?
Terminals a1 and a2 are classed the "run windings" these are supplied by a constant supply from a suitable switched and isolatable supply. The remaining terminals z1 and z2 are the "start windings" and are initialy supplied with a supply to "kick start" the motor in a given direction, the wiring can be reversed to these windings to enable the motor to start in the opposite direction. The supply to the start windings should only be for a short period to enable the motor to rotate and then disengage by the means of a centrifugal switch or time lagged contactor. So 4 wires, 2 to the run winding and the other 2 to the start windings. Any help? lee
Why do you use codenser in fan?
fan is a capacitor start capacitor run single phase induction motor. since single phase induction motors are not self starters, caused by discontinuty in stator mmf. so to iniate rotation single phase supply is splitted 90 degree apart by a capacitor to convert it to a 2 phase motor, which produces a continued synchronously revolving mmf in stator to start the motor. cool !!
Why you have to connect DC supply to the induction motor?
To start an induction motor we have to excite field. The excitation is done by connecting the DC supply to the field winding's.
What is the difference between a one phase and a three phase motor. And if a three phase motor is given a single phase supply will it run or not?
The difference between a single phase and a three phase motor is the amount of power conductors that feed the device. As to the other part of the question a three phase motor will not start or run on single phase. The phase angles on three phase are 120 degrees apart on a single phase system they are 180 degrees apart.
HOW TO REVERSE DIRECTION ON A single phase motor?
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.

What s the role of capacitor in a single phase induction motor?
to start the motor and give more current to motor to run
