NEMA34 (86mm) 2-phase stepper motor optimized for microstepping and give a good fit to the TRINAMIC family of motor controllers and drivers. They can be used in very space critical applications and allow high RPM due to their low back EMF. * NEMA 34 mounting configuration * Flange max. 85.85mm * 85.85mm * Step angle: 1.8˚ * Optimum fit for TMC239/TMC249 based driver circuits, e.g. TMCM-078
