Petrol-electric conversion

Posted by Rupert Connor on Monday, April 4, 2016 Under: Locomotives
Testing our petrol-electric conversion. After Helen's gearbox failed we decided to use the same general arrangement as Colin Edmondson's 'Scamp' design. Two identical electric motors are used. The petrol engine drives one motor, making it a generator. This generator motor is connected to the other (driving) motor via a reversing switch and PWM speed controller. Thus speed and direction control is provided without the need for a mechanical gearbox. Many thanks to Colin for his advice and the parts he provided to make this a simple conversion.
