Hollow shaft dc brushless actuators

Hauppauge, N.Y.— FHA series actuators feature a hollow shaft up to 45 mm in diameter, which is said to make them ideal for use in robotics, machine tool, and other applications where cabling, laser light, or shafting need to be passed through the center of the actuator.

Hauppauge, N.Y.— FHA series actuators feature a hollow shaft up to 45 mm in diameter, which is said to make them ideal for use in robotics, machine tool, and other applications where cabling, laser light, or shafting need to be passed through the center of the actuator. Because zero backlash, high stiffness “S” series harmonic drive gearing is used, these units claim continuous rated torques of up to 1,730 lb-in, and positional accuracy better than one arc-minute. Integral brakes are optionally available where position must be held when power is off.
