A SELLER, RECEIVED IT EARLIER THAN BEEN TOLD

Using this to make a custom lab instrument. With a driver that can micro-step this unit provides an incredible 7.8nm/step resolution. There is minimal backlash in the gearbox.
Chris Jacobs – 15 Feb 2016
The motor works great and the output shaft spins slowly as expected with such a high gear ratio. Only two concerns which prevented a 5/5 star review are that the motor did not have the standard 4 pin connector (just had 4 loose wires) and the motor is not compatible with a standard Nema 17 mount due to the gearbox attached to the front.
