admineOrbo replication 2 Orbo, Steorn No Comments

Yesterday’s post was a mistake. The hall switch is sensitive to a single magnetic pole on one side and to the opposite pole on the other side. I knew this and at the moment I was thinking that if the sensor didn’t sense I could just move it to the other pole. That is correct only if the same side of the hall switch is facing the other pole. This was not the case yesterday. I was lazy and didn’t think when I just moved the sensor around. The way to do it is to turn the sensor because it will work every time and does not depend on the situation at hand.

With my rotor the magnetic field is shooting up and down and not radially out the where the toroids are placed. This is not optimal, but having pockets in the rotor is  attractive seen from an experimenter’s point of view. I can easily play with different size magnets just to see what happens. This may or may not be the best way to replicate eOrbo. It is, however, a good way to learn more.

The motor was started with a single toroid and with strong enough magnets the acceleration is good. I like running it with a load and the load this time was fan blades. It accelerated to around 3000 RPM. In my first replication the load was the fan motor (converted to a generator) and I used two toroids. This means the two replications cannot be compared at this time.
