The basic design of induction motors has not changed in the last years, with latest and good insulation materials, pre-simulation for design, computer optimization techniques in design and using automated manufacturing devices have resulted in motors of less cost per kW, heating reduction and smaller physical size. Due to standards by International of physical dimensions and frame sizes the motors from most manufacturers are physically interchangeable and they have similar performance characteristics, dimensions and electrical distribution of multiphase coils are affecting on magnetic field density, because of difficulty in measuring magnetic flux in each point of the machine computer simulations help in machine design to demonstrate and adjustments in magnetic flux distribution. Three-phase and six-phase induction motor electromagnetic models are developed in two-dimensions in the finite element method based software-tool Computer Solutions (COMSOL) Multiphysics.
The paper deals with analysis of the situation in a six-phase induction machine. For this purpose, the method of space vectors is used. It is shown that higher space harmonic waves of current layer, flux density and flux in the stator yoke have to be considered especially when the stator is fed by unbalanced voltages. The equations of a six-phase induction machine are derived and relation between symmetrical components of instantaneous values and groups of spatial harmonics of the field in the air gap is shown. Also experimental verification of results from the mathematical analysis is presented in this paper. Values from measurements are compared with those of numerical simulations.
In this paper, two dual three-phase winding configurations are compared based on the Toyota Prius 2010 interior permanent magnet (IPM) machine. It is found that the winding configuration with single-layer full-pitched (SF) windings can improve average torque and reduce torque ripple in constant torque range. The winding configuration with double-layer short-pitched (DS) windings has better torque performance in a constant power range. Variable speed control of 3 phase induction motor manufacturers india.The electromagnetic performances of the two winding configurations when one winding set is excited and the other one is open-circuited are also compared. The DS winding configuration shows much better performance under this condition. Overall, the dual three-phase winding configuration with DS windings is preferred for dual three-phase IPM machines in electric vehicles. A Toyota Prius 2010 IPM machine equipped with DS windings was manufactured to verify the analyses presented in this paper.
Assuming that you checked the mechanical properties and the centrifugal force at the rotor at the higher speed from 50Hz to 60Hz, 50Hz 60Hz Converter and they are OK, then you have to consider that the flux in the machine will go down by the ratio of the increase of frequency to 60Hz. Also the inductances will increase, so locked amps will be down, Locked rotor torque will be down, power factor will change, and efficiency will change. No load amps will decrease. If you want to change the electrical design to make it like it was for 50Hz then you have to increase the number of turns of the motor, but you have to know what you are doing.Please note that except the change in the asynchronous speed of the motor machine, many other parameters will change. This will include the effective phase impedance of the motor, the current/voltage levels, etc. Also, please note that the torque-speed curve and the associated efficiencies will be affected by the change in frequency 60Hz to 50Hz.

In a 3-phase AC induction motor, there are three stator windings, each usually in two halves, with the rotor winding short-circuited by end rings. As the current passes through the coils on opposite sides of the stator, a two-pole electromagnet is established, creating a two-pole motor. Applying a phase to each of the electromagnets in turn creates the rotating magnetic field that is strong enough to start moving the rotor.
More winding can create more poles in the motor, with more complex control required but more accuracy in positioning the rotor. A four-pole motor is regarded as optimum for the torque and responsiveness needed to for the motor drives of electric cars, for example. But higher pole counts are only possible with more sophisticated control schemes.
The typical drive has three half-bridges, each delivering a sine-wave voltage to the stator. This uses power MOSFETs or IGBTs with high-voltage gate drivers, or power modules that combine the three half-bridges and related gate drives. These can use scalar algorithms that vary the voltage to determine the frequency of the phases, or volts/hertz. More sophisticated algorithms such as vector control or Field-Oriented Control(FOC) are used to control the frequency of multiple phases in high-end motors are now increasingly popular across the range of three-phase induction motors.
Polyphase motors generally cover three-phase motors using multiple poles.
A soft-start controller is used in three-phase AC induction motors to reduce the load on the self-starting motor and the current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of the system.
Induction motors can have inrush currents seven to ten times that of the operational current. Starting torques can be 3 times higher to overcome the starting conditions, causing mechanical stress on the components in the motor. So electronic soft starters use a control system to reduce the torque by temporarily reducing the voltage or current input until the induction motor reaches its synchronous speed.
A digital soft-starter controller continuously monitors the voltage during start-up, adjusting to the load of the motor to provide a smooth acceleration and the speed control. This is often done with connected silicon-controlled rectifiers (thyristors) controlling each phase separately to give the optimum control.Variable speed control of 3 phase induction motor manufacturers india.The torque generated in the rotor of a 3-phase induction motor is proportional to the flux generated by each stator pole, the rotor current and the power factor of the rotor. Direct torque control (DTC) is a technique used in variable frequency drives. It comes from estimating the magnetic flux from the voltage and current of the motor. This is compared to a reference value to control the torque.
This allows the flux and the torque to be changed quickly by changing the references, making the motor more efficient and reducing power losses as only the exact current is used. This also avoids the rotor overshooting, allowing more accurate control over the motor.

This project will focus on developing a simulation model of variable speed, variable voltage for an induction motor drive. The main component of this system consists of a 3-phase induction motor (DL 1021) and a 3-phase ABB inverter (ACS 550-01-08A8-4). Based on the actual 3-phase induction motor (DL 1021), the parameters such as R1, X1, R2, X2 and Xm is defined using certain tests which are open and short circuit test. Using mathematical equations and MATLAB simulation, others parameter such as starting current, maximum torque and rated torque will also are defined. For variable voltage variable frequency (VVVF), the ABB inverter will play a major role. Inverter section determines the voltage level, frequency level and the current level that a motor receives in order to control the motor speed. So, the inverter section will focus on the concepts study and parameter setting of an ABB inverter. Finally, this project will develop a simple manual of variable speed control system.
