The tipping of the brushes is to adjust the timing,and also to have two rotor segments in contact at once. This eliminates most of the arcing of the brushes,and reduces losses by way of heat. It also allows for the reversing of the magnetic field created by the stator coils to that of the rotors field.

See this video(if you havnt yet) of my early experiments,and you can see how much more efficient the standard RT is than an !off the shelf! motor that was designed to drive the fan used in the test.
The standard motor on the house fan is suppose to be 86% efficient minimum,but for arguments sake,lets say it is only 80% efficient. The RT is 40%+ more efficient at running the fan blade than the motor that was designed to do the job. Only 1 stator coil is being used on the RT at the time this video was made,as it was early days-as you will be able to tell with some of the descriptions i give lol.

Well that was impressive. I hadn't seen that before. Thanks. What is the better motor to work with? The washing machine or fan.? Which was the easiest to tune for optimum performance?

As opposed to 4 rotor segments?

The later vids it was across 1.5 ? I think I'll have to go back and check. It was the vid uploaded last night.

kEhYo neutralizes then shuts the coil off and allows the backing magnets to repel the rotor. He could power the coil from both directions with a DPDT current reversing reed switch. The same motor would then deliver twice the Torque. In attraction, the backing magnets would have twice the force with coil on in the same direction, then reversed to neutralize at TDC. kEhYo's circuit only delivers 1/2 the motor's potential power.

the fan motor is just a standard induction AC motor-no mods can be made. It was used as a benchmark for efficiency-so as i knew i was going in the right direction with the RT.

Sorry i didnt make that very clear-my mistake.
2 rotor segments at each brush-50% of the time there is 3 segments per brush in contact with each brush-so 4 segments at 100% and 6@ 50% time on all up.
