Hollow shaft stepper motor range offers simplified design options

31 October 2015

Mclennan has expanded its range of stepper motors with the new competitively priced HH series hollow shaft motors from USA distribution partner, Applied Motion Products.

With high-torque NEMA 17 and 23 motor frame options in a choice of stack lengths, the hollow shaft facilitates direct assembly of a lead screw without the need for a coupling - keeping hardware to a minimum and simplifying design for machine builders.

The hollow shaft also allows customised shafts or other power transmission components to be quickly added to the motor without the often-long lead times that specials may take and also enables small quantities of specials to be produced at reasonable cost.

The internal shaft diameter for the 17 and 23 frame motors is 5mm and 8mm respectively. The holding torque across the 2-phase HH series ranges from 0.45 to 2.3Nm with current ratings from 2 to 3A per phase (series). The motors are supplied with a detachable lead/connector pigtail for straightforward installation in the customer’s application.

The 200/step/revolution motors can be used with stepper drives across the AMP range, including the micro-stepping ST5 which offers sophisticated current control and multiple motion control options from simple streaming commands to Ethernet/IP communication.
