Excellent value, great features.
The driver has several great features. One in particular that is useful is the revering switch. You do not have to change motor coil poles to reverse the servo if its going the wrong way. The fit and finish of the driver is of good quality. I found no blemishes or defects in it. The cabling seems to be of good quality.
The motor is excellent in fit and finish. The bearings in the motor are tight, with no shaft slack, but rotate freely. The encoder mounted to the rear of the motor is enclosed in a sealed case, though not water tight.
Using this motor and driver combo I was able to spin the NEMA 34 beyond 40,000mm/minute. This would equate to an rpm of 3,200rpm which is incredibly fast for a large stepper motor. Above 3200rpm it would start to lose steps and fault, but that speed is far above the normal conditions this motor will run under.
