Yes.
Then it is not a three phase motor.
the three phase dc motor never seen yet motor eaither 3phase m/r or dc motor.
Sir, what is the cable size for 1.5kw 3phase induction motor 400v?
It is not advisable to run lower voltage motor on a higher voltage.
Its a servo.
Starting capacitors are only required for single-phase induction motors. They are not necessary for three-phase motors.
how will you start 3phase inuction motor using star delta stater
No, you only have phase a and b. The motor will run as smoothly as a 3 phase motor that has lost a leg of power. That is if the motor is designed for 208v in the first place. Not a good idea.
You don't. A three phase motor will not start unless it is connected to a three phase supply.
To see if the motor is three phase or single phase look at the motor's nameplate. There it will tell you what the voltage needs to be and what system phase the motor needs to be connected to operate properly.
If the motor is connected to an ungrounded delta supply service there will be no effect on the operation of the motor. If the motor is connected to a wye system supply service and the B phase grounds out, the motor's overload protection would take the motor off line from the electrical supply.
It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.
