The hollow shaft is also said to allow customised shafts or other power transmission components to be added to the motor without the 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 5 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. 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.
