1.8 Degree 8.7N.M NEMA34 85BYGH450B Bipolar Step Motor For CNC Router

1.8 degree 8.7N.m NEMA34 85BYGH450B Bipolar Step Motor For CNC Router

This 85BYGH450B hybrid stepper motor is 1.8° 2 phase stepper motor widely used for middle size cnc routers. Consider the measuring error, sometimes also called 85BYGH450B. The 14mm shaft diameter ensures stability in applications with belt transmission or planetary reducer. Also have the stepping motor with 12mm shaft with key, D shaft, etc.

Round or "D" Shaft: These are available in a variety of standard diameters and there are many pulleys, gears and shaft couplers designed to fit. "D" shafts have one flattened side to help prevent slippage. These are desirable when high torques are involved. "D" Shaft are widely used with planetary reducer to avoid slippage.
