Gearmotor and rotary actuator with strain wave gear

Our KAH and KAT families of rotary actuators with hollow-shafts use a backlash-free strain wave gearbox with an integrated BLDC motor and rotary encoder. Our KAS family of rotary actuators does not have the hollow-shaft, but has a lower cost than the KAH/KAT families. All three families are made by the manufacturer Kaiserdrive. The Kaiserdrive rotary actuators use the strain wave gearboxes of their sister company, Leaderdrive. Information about the gearboxes can be found here.
