Gearmotor and rotary actuator with strain wave gear

For strainwave gearmotors we work with our partner manufacturer Kaiserdrive. The Kaiserdrive KAH family of rotary hollow-shaft actuators (also called gearmotors) backlash-free strain wave gearbox with an integrated BLDC motor and rotary encoder. The Kaiserdrive gearmotors use the strain wave gearboxes of the Kaiserdrive sister company, Leaderdrive. Information about the gearboxes can be found here.

• High precision: absolute positioning accuracy of up to 10 arcsec
• High torque density
• Cont./Peak torques up to 557/800Nm
• Five reduction ratios (51, 81, 101, 121, 161)
• Hollow-shaft / throughbore: large-diameter throughbore, convenient for passing through cables, air pipes, laser beams, etc.
• Hollow-shaft inside diameters from 9-40mm
• Long life: the accuracy remains unchanged after more than 20,000 hours of use
• Zero backlash: strainwave gear technology
• Highly integrated gearmotor comprising: strainwave reduction gear, torque motor, electromagnetic brake, encoder
• Fast response: excellent dynamic response performance, ideal for laser processing, 3C automation equipment, etc.;
• Low vibration: low vibration and noise, preferred for applications such as semiconductors, medical imaging equipment, and precision instruments; 
• Ingress protection: up to IP67
• Maintenance-free: no regular maintenance, no need to change grease, etc.
• Voltages: 48Vdc, 110Vac und 220Vac
• Feedback: incremental or absolute (multi-turn)
• Optional holding brake
• Ingress protection: IP67

As with any type of gearmotors, the application is usually one which requires high torque, at lower speeds, in a compact package. The KAH series of gearmotors are widely used in CNC machine tools, laser processing machines, electronics and semiconductors manufacturing, general factory automation, medical equipment, robots, intralogistics automation, solar photovoltaic systems, LED equipment, testing equipment, printing machinery, precision measuring instruments and other fields.
