Induction motors as Selsyn drives
Electrical Engineering, 1933The power Selsyn unit, an adaptation of the wound rotor induction motor, provides accurate remote control of angular motion, using only an electrical connection. The characteristics of these units are described briefly in this paper, and methods of calculating their performance are offered. Typical applications of Selsyn drives also are given.

Switching drive of induction motors
Proceedings of the Institution of Electrical Engineers, 1963Recent developments in semiconductors lead to new possibilities of motor control in general and of the induction motor in particular. The latter type of motor, although the most simple in construction and therefore the most widespread in use, does not lend itself easily to speed control and feedback arrangements. The paper shows that electronic control

Adaptive Decoupling Control of Induction Motor Drives
IEEE Transactions on Industrial Electronics, 1990A novel control approach for a robust induction motor drive system with a voltage source inverter has been developed. In the scheme, the induction motor and its corresponding inverter gating signal are controlled using the decoupling control theory. In addition, an adaptive optimal speed regulator employing the model reference adaptive control (MRAC ...

Conference Record of 2004 Annual Pulp and Paper Industry Technical Conference (IEEE Cat. No.04CH37523), 2004
For years, the squirrel-cage induction motor has been the motor of choice for the pulp and paper industry, in both sine wave and variable frequency applications. Historically high torque, low speed applications used a combination of a reducer and either a squirrel-cage induction motor or a DC motor. This paper will address the use of an induction motor

Direct-drive induction motors: using an induction motor as an alternative to a motor with reducer
IEEE Industry Applications Magazine, 2005This article presents the performance and size comparisons of direct-drive induction motors with gearbox-driven systems. Three different low-speed applications with output speeds to the driven equipment ranging from 300-600 r/min is reviewed. In addition, permanent-magnet (PM) motor advantages and disadvantages are also discussed.

Induction motors for synchronized drives
Electrical Engineering, 1949THERE are two types of synchronized drives of two or more mechanically independent shafts commonly known: one is the “power selsyn” or “synchro-tie;” and the other might be called the “simplified selsyn.” The first system uses, besides one or more prime movers, individual selsyn motors for synchronizing.

Optimization of Self Bearing Induction Motor Drive
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018The purpose of this paper is to perform the radial position control of a three-phase induction motor with split winding by the current control of only two phases. The third phase current is obtained by the sum of the two controlled currents. The objective is to reduce the number of components needed to drive the motor and reduce costs.

With more than 85% of electrical motors, induction motors (IMs) dominate the market for electrical motors and consume more than 60% of total industrial electricity across the globe [1]. Their extensive use is a result of their strong low-cost design along with their reliability and cheap maintenance.

Sensorless induction motor drives
IEE Seminar on Advances in Induction Motor Control, 2000The desirability of eliminating mechanical shaft sensors for induction motor drives has led many manufacturers to include sensorless vector drives to their product range. However, current generation sensorless drives are unable to exhibit the same performance as sensored vector drives, particularly at frequencies below a few Hz.

Stabilization of sensorless induction motor drives: A survey
2013 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD), 2013This paper presents a survey of methods for stabilization of sensorless induction motor drives. Some frequently suggested flux and speed estimators - such as full- and reduced-order observers - are reviewed, along with their key properties. Three commonly occurring instability phenomena are discussed, as are methods for preventing them. The methods are
