A Hartnell governor has its controlling force (Fc) given by Fc = ar + b, where r is the radius of rotation and a and b are constants. The governor becomes isochronous when
a is + ve and b = 0
a = 0 and b is + ve
a is + ve and b is - ve
a is + ve and b is also + ve

Fc = ar + b --> Unstable.
Fc = ar - b --> Stable.
Fc = ar --> Isochronous.
