[sci.electronics] Variable speed motor control

... not to mention what the inductive backlash can do to your *transistor*!

The appropriate fix is a clamp diode around the motor, I suppose, but that
raises another question: Does the motor behave differently when it's allowed
to backlash, instead of being clamped?

And another question I just thought of: What exactly does placing a clamp
diode around the *transistor* do?  It seems to me that the motor would try
to backlash through the power supply.  I often see these extra diodes as part
of Darlington packages, etc.
