Experimental result shows that the system can measure well torque-speed characteristic of induction motor.
A novel inverse decoupling control method with the adaptive rotor resistance estimator for induction motor is proposed in this paper.
The voltage and torque equations of induction motor during hunting are formulated at first, then the asynchronous and damping torque coefficients are derived.
In order to implement an energy-saving method which keeps iron loss equal to copper loss using variable-voltage in light load, induction motor parameter identification at any moment is a key problem.
"We are now trying to revisit very old technology and remove the problems" in induction motors.
The stator flux-oriented direct torque control is widely used in high performance motion control of induction motors.
totally enclosed fan-cooled type induction motor
Then, a DTC induction motor servo control simulation model is established, which adopts the self-learning fuzzy in velocity observer.
An induction motor, by contrast, can be cooled passively-and thereby dispense with the hefty radiator, cooling fan, water pump and associated plumbing.
A decoupling control approach based on inverse system has been used for the innovative five degree-of-freedom bearing less induction motor, which is multi-variable, nonlinear and high coupling.
In the past the main problem with asynchronous induction motors was the difficulty of varying their speed.
The adaptive flux controller and speed controller based on neuron are presented for the induction motor vector control.
The results of the simulation proved that the soft starting control can effective reduce start current as high voltage induction motor start up directly and the motor could start up smoothly.
Considering the large startup current of induction motors, this paper presents a fuzzy control soft starting system.
In this paper GTR Base-drive circuits on PWM variable frequency and variable speed systems for induction motor drive are studied.
" Output, voltage and speed ratings of three-phase induction motors (from 0.6 to 100kW)"
Self-excitation of induction motors caused by output LC filters of variable voltage variable frequency(VVVF) power supplies is harmful both to the motor and the power supply.
Based on adaptive model reference following system we present a novel control strategy of induction motor.
The principle of the soft starter is reducing the voltage applied to the stator of the induction motor by control the triggering angle of the thyristors in order to limit the starting current surge.
Meanwhile, the induction motor’s big advantage—apart from its simplicity and ruggedness—has always been its ability to tolerate a wide range of temperatures.
