Yes, by using a DOL Starter, which gives a controlled "soft-start" for the motor even though it is always connected in delta configuration.

In this type of starting a 3-phase motor, full voltage is applied to the motor through relays and contactors. Its is the most common type of 3-phase motor starter used.

DOL means Direct On-Line starter.

No, a three phase motor will not start if one leg of the motor feeder is open. The motor will stay running once the motor looses a leg butnot for long if the proper motor protection is provided. The motor protection will sense theline failure and disconnect the motor from the voltage source.

No, the motor doesn't start by itself. But if you rotate it by any external force it'll work as a single phase induction motor at .577 of it's original rating.

Stater is an electrical device which is used to limit the starting current and run the motor with rated load current, It provides induction motor for safety load behind rated load current.

How many types of 3-phase induction motors are there?

One way is to add a capacitor and some extra field windings. Starters are needed because the starting current in an motor may go as high as 6-7 times its rated current. Some of the methods used for starting motors are, Direct online starters, Auto transformers, Soft Starters, Variable Speed Drives, Intelligent Motor Controls.

Why did general motors start?

because Ford needed to have some competition! :) Durant needed a holding company for the stock trading he did as his Buick Motors were being sold to McLaughlin Car Company in Canada for 15 years and McLaughlin traded 500,000 shares of his Company for 500,000 shares of Buick, The shares McLaughlin held in Buick stock were traded for General Motors Holding Company stock. R S McLaughlin was Director of the Company when Durant made a bid to buy Ford for 8,000,000 and the Bankers gave Durant 5 years away from his title in the Company allowing him to start Chevrolet in 1911.

What size armoured copper cable needed for 75 kW motor?

Wire sizing is based on the motors full load amperage. The amperage can be calculated but a voltage has to be stated. I = W/E. Amps = Watts/Volts. Restate the question with a voltage and an answer can be given.
