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.
Using expEYES Junior
The motor is powered from the SQR2 but the duty cycle of the pulse on SQR2 should not exceed 50%, to avoid excess current drawn by the motor. 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.
The motor is powered from the PULSE output of expEYES. You can change the dutycycle to change the speed of rotation, but do not exceed 50%.
