Yes, most large motors are three phase. Usually single phase motors only go up to 10 HP. Larger than this and the wire size and contactors used to control the motors becomes extreme. For example a single phase 10 HP motor on 115 volts draws 100 amps. The same single phase motor on 230 volts draws 50 amps.
The same 10 HP motor on three phase system draws the following amperage; 230 volts is a 28 amp draw, 460 volts is a 14 amp draw and 575 volts is a 11 amp draw.
As you can see the higher the voltage becomes, the smaller the wire feeder size is needed and much smaller size contactor can be used to control the motor.
Generally for big and major dams,motors are alone not used,all this type dam gates will be controlled manually.Because it is not easy to conrol the large dam gates by motors. But for the dams with single gates,used for irrigation purpose,in canals,we can use the synchronous reversible motors to control such type of dams.
All motors work on magnets dude!!!! so yes magnet motors do work irrespective if they are AC or DC :D!! hope this is what you were looking for
One can sell a large number of electric motor in buy and sell online auctions such as the following; H and H Buying and Selling, INC, Indiamart and EcReCon INC also buy and sell electric motors.
BTD stands for bearing temperature detector.
The difference between crown motors and regular motors is that crown motors is a company, and regular motors are not. Regular motors, are the motors that can be found under a car hood.
There are two large motors in the top of the tower. They are 15 feet tall and 30 feet wide. These motors power all elevators in the ride.
Since electromagnets are used in most large electric motors,the answer is almost all industry.
For better ditection
All motors have different settings and not all motors are adjustable, some are fixed.
The Electric Motor Warehouse sells pool pumps and motors; other pool accessories like fencing, steps, etc.; electric motors like bathroom fan motors, air compression motors, etc.; and specifically a large collection of Dayton electric motors, including furnace blower motors and pressure washer motors.
All motors have a set number of poles for the speed they are designed to run at. 3600 rpm are 2 pole,1800 rpm are 4 pole, 1200 rpm are 6 pole, ect.
Most cruise ships are run by electric motors. Several large gas turbine engines produce power for the electric motors. Thre turbines also produce all the ships elctrical power as well.

Motors are used in a variety of appliances and industries all over the world. Washing machines, dishwashers and electric fans all have motors. Motors are also found in milling machines, hand drilling machines, and gas pumps.

phones and electric motors definitely do!
