Answer (1 of 4): The voltage between two phases in a three-phase supply is equal to the phase voltage multiplied by the 120 degree phase shift, or 1.73. The Phase voltage is the voltage between phase 1, 2 or 3 with respect to the neutral line. (Around 120V in US and a few other places, and aroun...
128,463. In a three phase motor system, the direction of rotation is changed by swapping any two of the phase wires. All the wires are essentially equal so it doesn't matter which two are swapped. The intention is that one phase (L1 for example) stays permanently connected and the path between L2 and L3 is controlled by operating either Triac 2 ...

Abstract—Induction Motors are rugged, robust and widely used in industrial applications. Field oriented control (FOC) or Vector control is an efficient method to control either the speed or the torque or both of the three phase Induction motor. FOC converts the complex stator currents into two orthogonal components, one of which is responsible for speed control, and the other for the ...
system consists of the following two main sections: Speed control using VFD, PLC-SCADA based Induction motor drive control. The three-phase induction motor is used in a VFD system. As inducti on motor runs only at a steady speed rate so VFD is attached so that it can run at a varying speed.

Abstract: The hardware and control algorithms of low cost scheme for integrated dual AC motor drive system with the function of a rectifier to perform as single-phase on-board electric vehicles (EVs) integrated battery charger are presented in this paper. In the system, a five-leg inverter is proposed; two legs are for the auxiliary motor, three are needed for the main traction motor.
A three-phase motor must be wired based on the diagram on the faceplate. The first step is to figure out the voltage of your phases. In the United States, for low voltage motors (below 600v), you can expect either 230v or 460v. That being said, there is a wide range of different motors and what you have on hand can be completely different.
