Motor run delta connection because in delta connection it is less ampere needed and it sometimes it change the wye connection because of the available suply
There is no need to place a 6 pole disconnect to isolate the motor in the field. The motor's leads at the motor's terminal box have to be wired for a delta connection. The star delta contactor in the MCC only has three wires on its output. Six wires do not have to be taken directly to the motor. The voltage is reduced at the start of the circuit when the starter in in the star configuration. From the star configuration it changes to the delta configuration. So as you can see only a three pole isolation switch is needed in the field to isolate the motor from its supply.
The cable size depends on a few factors, such as the supply voltage, the method of starting the motor, (direct-on-line, or star delta) and the length of cable required to compensate for voltage drop. Also, if the cable is copper or aluminum.110 kW motor has a rated current of 200 amps at 415 volts, so the correct copper cable size would have a cross-sectional area of 75 square mm., if the motor is started direct-on-line.At 660 volts, the rated current would be 118 volts and the cable size would be 35 square mm.
first calculate the full load amps of the motor by using formula, line amps = KW * 1000 / (line volts*1.732*P.F) Of the mentioned motor the amps will be 96 amps at the P.F 0.8. The motor will have star delta starter so the cable size would be 2 runs of 3c x 70 sq mm AL if laid in air.

voltage drop is be a problem.
question is incomplete, I think you ask how much current consumed by this motor. for starting this motor we need a star/delta starter and a three phase supply.

Whoa, this is a serious motor! The generator needed would cost in the neighborhood of $50,000.00 US, would require permits to install and run, and would require professional installation. Check your telephone directory for generators. 270v is an unusual number in the US, what country are you in? Curiously, if this is a 3-phase motor, your numbers don't add up. 270v at 200a is only about 93kw of electrical comsumption, this motor would not be able to produce 185kw of output.
On a star delta starter a motor overload or a motor going to ground and cause a short circuit will cause the overload protection to trip. These overloads have to be reset before the motor can be restarted.
A motor from a 1991 Oldsmobile will fit into a 1996 Oldsmobile Delta 88. The motor mounts will need to be changed.
It is a type of starter that allows a motor to be started across the line by starting the motor with a reduced inrush current. The motor is started in a wye configuration until it gets up to speed and then a timer drops the wye contactor out a draws the delta configured contactor in. The motor then operates in a delta wired configuration.
A forward reverse star delta is a two in one motor starter where a motor first runs on star connection and then changed to delta connection after a time which has been set. The motor direction can be changed, whether forward or reverse
