An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to ...

These motors vary in size and are used in toys, electric vehicles, lifts, hoists, and steel rolling mills. 1) Shunt Motor It is a type of DC motor where the field winding is connected parallel to the armature winding of the motor.
Electric locomotives, steel rolling mills, hoists, lifts, and cranes are examples of heavyduty applications. Shunt DC motor. Constant speed line shafts, lathes, vacuum cleaners, woodworking machines, laundry washing machines, elevators, grinders, and small presses are all driven by DC shunt motors. Threephase Synchronous motor.
Electrical steel is appropriate for power transformers, electric motors, generators, and other electrical equipment because of this combination of elements' efficient magnetic performance. ... Fusion welding is a common method used to join electrical steel laminations, especially in highperformance motor applications. This method provides a ...
To properly select AC induction motors for any application, the speed vs. torque requirements of the driven equipment must be understood. It is an easy mistake to believe that a 400 hp 1200 rpm motor, which would function well in a low inertia fan application, would also work aptly in a kiln application. However, the load torque requirements of ...
1. DC Series Motor Since it has high starting torque and variable speed, it is used for heavy duty applications such as electric locomotives, steel rolling mills, hoists, lifts and cranes. Go back to Motor Types ↑ 2.
Rolling mill DC motors are best at low speed, high torque applications, while AC motors typically need to run above 800rpm to be cost effective. Also the case for higher efficiency of AC motors is many times negated by the wasteful braking methods of some AC drive systems. All this being said, for motors below 200300kW, or when new products ...
SynRM motors deliver full torque from zero speed Lower losses mean SynRM motors run cooler A temperature reduction of 10 degrees means the winding lasts twice as long Synchronous reluctance motors High Dynamic Performance motors (HDP) Optimized electrical and mechanical designs for demanding applications in rough operating conditions
I'm guessing here, but I think these are WardLeonard Motor/Generator sets. This is a method of adjustable speed control used in steel rolling mills until about 1985. A large AC motor operating on line frequency drives a DC Generator. The field (stator) of the DC Generator is controlled by various methods.

A motor used for cording is required to accelerate a drum having a large moment of inertia. It is required to withstand prolonged accelerating periods. To meet these requirements the motor selection must be made. The motor selected must have a very high starting torque and low starting current so that starting losses are kept to a minimum.
