April 18, 2013 - DLE-TEST24 : This is the continuation of the test DLE-TEST23. Here is a simple test of the Robert Adams' motor (very similar to the John Bedini's unipolar motor/generator) piloted by the APMC v1.0 (Arduino Pulsed Motor Controller). A LED Spot of 24 Leds (1.6W/12V) is only powered by the Back EMF pulses from the motor coil. A PC computer is connected via the USB port of the Arduino Mega 2560 board, the telemtry datas (time base, RPM, pulses delay and pulses duration, user datas and computed datas...) are fully used with a spread sheet on the computer.

Here is the configuration of the test :

Below the detailled diagram of the APMC and its control board :

A wattmeter is connected in serie with the spot led used as the output load.

A double fast switching HFA25PB60 diode and a filtering capacitor is connected the load.

The motor coil is a 5mH air core coil.

Here are the measurements of the INPUT DC voltage and current without the load :

Here are the measurements of the INPUT DC voltage and current with the output load (the spot LED) :

Below, the curves of the turn speed with and without the load.
We observe an slightly increase of the RPM and a decrease of the input power (-0.79 W) when the motor is loaded (1.9W).
