20% PWM duty cycle and a 24V power supply is about 4.8 volts to the

be surprised if it took 10 or 12 volts to overcome internal
friction.
A standard test for servo motors is to apply a single "D"
cell. The motor should turn VERY slowly, maybe 5-10 RPM,
but move smoothly. If the movement is "lumpy" or it doesn't
move at all, then it is a poor motor, or having a problem.
