Re: [CAD_CAM_EDM_DRO] Re: bridgeport boss servo

I would stick with the 20A drive. 6.8A stall current is the continuous
stall current. In other words the motor can handle 6.8A continuously
without damage. The peak current (and hence torque) is much higher than
this but you can't sustain it for any great length of time. This allows
you to push 20A or more through the motor while accelerating. This is
one of the big advantages of servos. Steppers can never supply more than
their rated torque while sevos are capable of very high torque in short
bursts.

Increasing the voltage increases the motor's maximum speed. The BP is
designed for slow steppers so your servo will never spin at anything
like it's maximum rated speed anyway.
