MyE.R.S. laboratories researches, develops, and prototypes revolutionary energy conversion systems. The types of systems developed here are of (but not limited to) electromagnetic, electromechanical, and mechanical type systems.
Presented are a few of my invention projects:
SRM Controller with SRD – In 2008-2009, designed and prototyped a Switched Reluctance Motor (SRM) controller that incorporated the SRD system below. The new controller was applied to a self-sustaining electric generator system to demonstrate proof of concept. The SRM shaft is mechanically coupled to an automotive alternator to provide self-sustaining and usable electric power. The motor for this project is an Ametek Infin-A-Tek Generation II industrial vacuum motor. It is a two phase switched reluctance motor with 4/2 topology and is 1500W. The only thing changed was the controller electronics. The new circuit uses the asymmetric half bridge topology, common for SRM controllers, with hysteretic current control and a DC link boost capacitor. The alternator is connected to a 12V motorcycle battery to excite the alternator and the output of the alternator is used to power a 1500W inverter for 120VAC, 60Hz, single phase output power. The input to the motor is 120VAC, 60Hz, single phase power.
Series Resonant Driver motor system is a revolutionary way of driving switched reluctance motors which is more efficient than conventional switched reluctance motor driver systems. The Series Resonant Driver (SRD) motor system has the performance similar to a gasoline engine and provides 2 times more range, or better, of a conventional electric motor system with the same battery pack. The SRD is designed for applications such as electric vehicles, power lawn and garden, small aircraft, and just about anything that would normally use a gasoline engine. This system takes advantage of the phase inductances in a switched reluctance motor where they are connected to capacitors to form a series resonant circuit. The system needs only to replace the switching and copper losses of the circuit, after each half-period, onto the charged capacitor. To see how this works and current status, go to the Series Resonant Driver motor system link.

Magnetic Circuits page contains a couple of the most potentially useful magnetic circuit concepts that I have tried out plus some discussion about known phenomena that I believe could be very useful. The circuits as presented here use permanent magnets, but may be more useful by using a combination of permanent magnets and electromagnets.
