Hello,
I have a series of motors, 2 bipolars and 1 unipolar. The unipolar is ok it works and move only when current, but the bipolars, if i not put current then they move easy (by hand, ..) and thats a problem, cause that means i cannot connect anything cause it will be in movement until i give power (current).
What the matter ? how can i fix that for that bipolars motors dont move/runn/turn by hand ?
I upload o video that shows that: http://youtu.be/7_Y-uubVH20
Why some Motors can be moved by hand when not current

Re: Why some Motors can be moved by hand when not current
The smaller motor is more difficult to rotate by hand because it has a 16:1 ratio gear-train between the motor shaft and the output shaft. This increases the effective detent torque by a factor of 16.
The larger motor is not geared so you are turning the shaft directly.
