April 30, 2013 - DLE-TEST26 : This is the continuation of the test DLE-TEST25 about the unipolar (North pole) motor invented by John Bedini and piloted by the APMC (Arduino Pulsed Motor Controller) v1.0b. It has been observed that, when a 2W LED Spot (24 Leds) is only powered by the Back EMF pulses from the motor coil :
In this new test, I have connected a 12V lead battery instead of the 24 leds spot. This battery is only charged with the "BackEMF" pulses from the motor coil. A PC computer is connected via the USB port of the Arduino Mega 2560 board, the telemetry datas (time base, RPM, pulses delay and pulses duration, user datas and computed datas...) are displayed on the computer and also the LCD screen of the APMC. The battery voltage is recorded with a digital scope Fluke 123. When the battery is charging, the input power drops dramatically and the RPM speed is doubled.
Here is the configuration of the test, the initial battery voltage is 11.23 V
The battery is a lead battery of 12V, 1.3Ah/20HR
Below the detailled diagram of the APMC and its control board :
Below a detailled photo of the John Bedini's unipolar motor.
The motive pulses are generated by the APMC v1.0b firmware installed on the Arduino MEGA 2560 microcontroller board.
We can observe that the battery is able to charge with only the "BackEMF" pulses coming from the motor coil...
Here are the measurements of the INPUT DC voltage and current :
When the LOAD IS CONNECTED the RPM speed is DOUBLED and the INPUT POWER DROPS dramatically.
