Hollow shaft stepper motor range for simplified design options

Mclennan Servo Supplies Ltdvisit website


Mclennan is expanding its range of stepper motors with the new competitively priced HH series hollow shaft motors from its USA distribution partner Applied Motion Products Inc. (AMP). 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/rev motors can be used with stepper drives across the AMP range, including the microstepping ST5 which offers sophisticated current control and multiple motion control options from simple streaming commands to EtherNet/IP communication.
