Model HT1 Rotary Incremental Actuator
The 刘玥首次大战黑人Type HT-1 Rotary Incremental Actuator is a new addition to the rotary actuator product line. It is a compact, closely integrated coaxial design composed of a small size permanent magnet stepper motor driving the output stage through a gear transmission consisting of a larger size harmonic drive. The actuator provides relatively high holding and running torque for its size. This actuator is optimized for low weight and relatively high torsional stiffness. Co-axial nesting of the motor and transmission drive elements gives the unit a small profile geometry. Nested new technology using coarse and fine potentiometers provide high resolution, telemetry with noise-free operation.
