a Drive 5 - A 5000 HP, 1200 rpm synchronous - induction motor with liquid rheostat and dc field excitation to a dual pinion gear driven mill. For the power supply in this study, four different scenarios will be considered as a power system in order
Difference Between AC and DC Motors Commonly ran by an AC variable frequency drive, an AC electric motor operates by applying alternating current (AC) power to the electric motor. An AC electric motor consists of several parts but the main parts are the stator and rotor.
Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. Larger DC motors are currently used in propulsion of electric vehicles, elevator and hoists, and in drives …

a DC motor can also be a generator. a spinning DC motor generates a current and voltage. The difference between applied power to the motor and generated power from the motor determines the motor drive. The controller measures the motor feedback to determine the speed of the motor. A variable resistor or circuit controls desired drive to the motor.

Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.
I got DC servos (Dynetic Systems 220014A) for my bigger mill there for 40 bucks each, when the cheapest one of the same characteristics I found was 70 bucks (chinese Keiling motor). I hope my answers are useful, and thanks for stopping by.
