Re: A little experiment on demagnetization

Jon,

You are right, it can lead someone down the primrose path because a
1/3 loss in torque often won't be noticed if the motor is lightly
loaded. When it is taken to the limit, there is no baseline to
compare against to see you are getting only 2/3 the performance.
