As a direct drive, the new hollow shaft motor operates backlash-free and can be integrated into various applications with minimal effort. It achieves high performance values in terms of both speed and torque. Its particularly large aperture has a diameter of 40 mm. The drive is characterized by its low weight and flat design. Thanks to minimal wear (only on the ball bearing), it is designed for maintenance-free continuous operation.

The DM66200H hollow shaft motor offers a new drive solution for applications where a large aperture is required. The rotor runs around the aperture and directly drives the mechanics arranged around it without a gear ratio. Faulhaber 's proven stepper motor technology is used here. Due to its design, it is highly energy-efficient and requires neither a brake nor an encoder.

Torque, speed, precision

Despite the large aperture, the moving mass of the rotor remains low, so that speeds of up to 2,000 rpm are possible. The motor achieves a dynamic torque of up to 180 mNm and can move correspondingly large loads. With a high resolution of 1.8° in full step, it can perform positioning tasks precisely in an open loop.

Originally developed for applications in precision optics, the DM66200H hollow shaft motor is suitable for numerous fields of application. It can be used wherever cables need to be routed through the aperture or the opening is required for the passage of gases, liquids or light signals. In addition to the field of optics - for example for microscope stages, apertures, zoom lenses, laser beam control, etc. - it can be used for impellers and prostheses, in robotics and for a wide range of control and positioning tasks. Other possible applications include rotary tables, antennas and air and gas extractors.
