Twin Rotor Bedini DC motor
« on: September 13, 2008, 11:22:49 PM »
Hi,Ive been working on Twin rotor Bedini motors for a while and i thought i would try this new DC Bedini motor in that config with some good results.
1 rotor spinning drawing 18mA
2 rotors spinning drawing 18mA
I am getting 100% more mechanical output with the 2 rotors.I don't have a tacho but the wind down time is the same for two rotors as it is for 1.
Here is a video

Excellent work jonnydavro,

I have also wondered for a while why we are not using both sides of coils. I also did some tests on using both sides of a coil back in May. Not Bedini energizer though but by using a shaded pole motor and cutting the coils laminate core to create a 2 pole motor. I also cut the rotor in a z shape. Here is a video of which I was also collecting the collapsing field of the coil and filling a 400v 3900uf cap at a good rate without loosing any mechanical work from the motor. In fact it turned a little faster when collecting the BEMF

Just though I would share ;) and say you are doing some great work.

Keep it up!... we need this.

@cyclopz i don,t no yet to early to say.

@gotolucThats a sweet little motor.You've put some thought into that,whats become off it?
It seems daft to me not to use both poles as we are trying to build highly efficient motors and we normally use only 50% of the magnetic field
Anyway Thanks for your kind comments.
