The first part of this two-part paper described the starting transients of a slip energy recovery IM drive using the rotor rectifier and a single resistor instead of three resistors and an ac circuit breaker. The starting transient was divided into three stages; the first was the resistance starting, the second was the connection of the inverter and the third was the disconnection of the starting resistor. The diode bridge rectifier imposes constraints onto the machine equations; the relevant equations for all three stages were developed in detail. This part presents a flowchart for the solution of the system equations and presents detailed simulation results, backed up with extensive experimental verification.

STARTING TRANSIENTS IN SLIP ENERGY RECOVERY INDUCTION-MOTOR DRIVES .1. FORMULATION AND MODELING
AKPINAR, E; PILLAY, P; Ersak, Aydın (1992-03-01)
A detailed study of the rotor phenomena including the rectifier commutation angle and inverter harmonics is facilitated by the use of the actual rotor conduction sequence variables instead of transformed variables that are used in most other IM drive systems. The starting transients of slip energy recovery IM drives comprising three stages are presented here; (a) the starting from zero speed with a starting resistor connected to the output of the rotor rectifier; (b) a transition period in which the invert...
Implementation issues of real time position estimation for induction motors using rotor slot harmonics
Ertan, Hulusi Bülent; Keysan, Ozan (2013-11-15)
In this paper, an approach to identify rotor slot harmonics, from motor currents or from induced voltage in an internal or external search coil voltage is described. The importance of this method is that instantaneous value of the rotor slot harmonics can be determined in real time. In this manner, it is possible to determine motor speed or rotor position of a motor in a short enough time, for use in vector control. This method is independent of motor parameters. Using this method an additional feedback bec...
Sliding Mode Control Of Permanent Magnet Synchronous Motor Fed By Wind Turbine Generator Taking Saturation Effect Into Account
Benchabane, F.; Titaouine, A.; Bennis, O.; Guettaf, A.; Yahia, K.; Taibi, D. (2011-09-10)
In this paper, we present the voltage build up process and the terminal voltage control of an isolated wind powered induction generator driven by a variable speed wind turbine using rotor flux oriented vector control. A description of the studied system is provided, and a simulation study is presented. The model used for the autonomous induction generator is a diphase one obtained by application of the Park transform. Theis model permits, when adopting some simplifying hypotheses, taking account the saturat...
ELECTRICALLY DRIVEN FLOWS IN MHD WITH MIXED ELECTROMAGNETIC BOUNDARY-CONDITIONS
Tezer, Münevver; ARIEL, PD (Wiley, 1988-01-01)
Flow of viscous, incompressible, electrically conducting fluid, driven by imposed electric currents has been investigated in the presence of a transverse magnetic field. The boundary perpendicular to the magnetic field is perfectly conducting partly along its length. Three cases have been considered: a) flow in the upper half plane when the boundary to the right of origin is insulating and that to the left is perfectly conducting, b) flow in the upper half plane when a finite length of the boundary is perfe...
Determination of rotor slot number of an induction motor using an external search coil
Keysan, Ozan; Ertan, Hulusi Bülent (null; 2009-12-01)
This paper describes determination of the number rotor slots of an induction motor from the induced emf in an external search coil. This information is needed in prediction of motor speed from the external search coil induced voltage. The approach is based on identifying saliency harmonics and rotor slot harmonics, via FFT analysis of the external search coil emf. The proposed approach is tested on an induction motor driven by the mains supply. The experiments are repeated with a PWM supply. It is shown tha...
