AC generator

Rotating a coil in a stationary magnetic field or keeping a coil in a rotating magnetic field will induce an AC voltage across the coil. We have chosen the rotating magnetic field option, by rotating a permanent magnet using a DC motor. The motor is powered from the PULSE output of expEYES, where you can change the dutycycle to change the speed of rotation.

 Figure shows generation of a 2-phase AC by using two coils. The phase difference between the two AC outputs is decided by the angle between the axes of the two coils. In the normal 3-phase supply lines, it will be 120 degrees.
