Hi metalspider,

just wanted to write you seem to have a COP of  2, if I am not mistaken.

I wonder why you deleted your text?

Hi.

What was his words before deleting his text....
Can you remember and recreate it, Gyula?

Hi Ergo,

Well I try and hope Metalspider agrees here....

He asked what the COP of a magnet motor was.

Motor Setup: 

the rotor is of one arm and at both ends there are two permanent magnets fixed.   
The stator is one electromagnet.
                     
His measurements: 

output torque is 0.31 Nm at 193 RPM

input to the electromagnet in case of one of the magnets: 254V @2A   0.4msec pulse
input to the electromagnet in case of the other magnet: 262V @ 9A   1.2msec pulse

Maybe I am mistaken but I figured a COP of about 2.

Interesting, a new magnet motor or just the old trusty one!
