Hi Robert,
Thanks for the further details. Sorry I do not get what you mean on counter emf? For me it means just the (unwanted) induced voltage in the stator coils whenever the rotor magnets are in motion. And if the induced voltage is 80 Vpp, then is not it just the counter emf? I may misunderstand something.
Can you recall when you loaded the shaft of the motor, the input current went up accordingly?
Well, 100 W output is very good indeed when the input is also 100 W. Can you recall the DC input voltage amplitude you gave to the motor and how you measured the output power?
Thanks, Gyula
PS: From tomorrow I will be away for 3 days.
