An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type.
Sensorless Speed Estimation Of An Induction Motor In A Over the past decades, fault diagnosis (FDI) and fault tolerant control strategies (FTC) have been proposed based on different techniques for linear and nonlinear systems. Indeed a considerable attention is deployed in order to cope with diverse damages resulting in faults
Induction motors. GE's induction motor technology –medium power and large power– delivers high reliability and efficiency, primarily by drastically reducing the rotor's parts. It means a leaner, lower maintenance motor that consistently delivers the power you need. With the recent advances of GE's high powered, variable frequency drives, induction motors (medium power and large power) can ...

Working Principle of Three-Phase Induction Motor. The stator winding is overlapped at 120˚ (electrically) to each other. When a three-phase supply is given to the stator winding, the rotating magnetic field (RMF) induced in the stator circuit. The speed of the rotating magnetic field is known as synchronous speed (NS).
Wound rotor induction motors (WRIM) have been popular for decades in the cement and mining industry for starting and driving large grinding mills. In fact, until about 1985, a wound rotor induction motor was the only large ac motor that controlled starting characteristics and adjustable speed capability. Stator R ot r Slip Rings 3-Phase stator ...

I do have two mills exactly the same, except one has a 20 hp gas and the other has a 7.5 electric. The electric to be the same, as the gas needs to be 10 hp. The 7.5 hp can not keep up with the 20 hp gas now. The reason for this is the gas engine produces a power stroke every two revs. The electric produces power every rev of the motor.

Answer: Raymond is quite right. However, I'd like to add that often large induction machines are used with variable frequency drives (VFDs) these days, they have similar speed control, smaller footprint and lower operating costs than machines with slip rings or commutators. I've been in a Kawas...
The induction motor is the most utilized electric motor in any industry that employs a rotary mechanism. Roughly 50% of global electric power produced is used to run induction motors. Electric locomotives, textile mills, compressors, pumps, fans, and even your hair drier – induction motors are just everywhere.
Induction motor Synchronous motor Induction motor Size of indicates quantity of motors. Introduction AC adjustable-speed motor drive systems have been established as the preferred technology for new rolling mill installations and extensive modernization projects. The AC adjustable-speed motor drive system provides metals mills with many
Answer: In DC Motors Speed and Torque control is pretty easy. Speed is proportional to Armature Voltage and Torque is proportional to Field Current. But DC Motor require lots of maintenance and usually they are quite bulky. In AC Induction Motors speed and torque control is somewhat difficult. ...
