Review on Maximize Precision and Efficiency with the Torque Stepper Motor 425Oz Router by Andrew Walton

This stepper motor fits my application very well and exceeded my expectations. 2200 RPM, which translates to 11,000 mm/min or over 400 inches per minute for a 5mm pitch. The mass moved during these tests was 60 pounds. Of course, the torque at this speed is practically negligible for a given voltage, but it is still an indicator of where the limits are. Some details of the tested setup are given below. Motor driver: M542T (4:1 microstepping). Power supply: 48V/5A (adjusted to 49.5V). Meanwell NDR series. Coupling. Methods: NSK 35 mm linear guides. Ramp profile: trapezoidal curve at 600 mm/s^2. While I haven't tested this, I believe the voltage limit for this motor is around 60V, so a few hundred can be squeezed out. more rpm.Other comments:1. Because of the large shaft size, cheaper non-bolted couplings are bulky and poorly balanced.2. Separate cable connectors - most inexpensive stepper motors are like this, but I would prefer them as cables, or even better, fixed bullet connectors like a standard M12 connector.
