The GP 6 S micro spindle gear has a diameter of six millimeters and is now also available in a metal version to provide a spindle drive with optimized value.

Spindle drives are the perfect solution for linear positioning systems, lens adjustment, or syringe pumps. If the drive also has to be compact, then maxon motor’s GP 6 S spindle gear is the perfect choice. To provide a cost-effective alternative to the ceramic version, it is now also available with a metal spindle.

Combinations with maxon DC motors

The GP 6 S spindle gear is suitable for a wide variety of linear drive solutions. The maximum feed velocity is 15 mm/s, at a force of 10 N. Integrated ball bearings ensure that this drive stands up to high axial loads. The gear easily combines with the maxon DC brushed motor (RE 6) and DC brushless motor (EC 6).

More data and details about the new metal version of the GP 6 S spindle gear are available online at www.maxonmotorusa.com.

Digital SLR cameras can deliver extremely sharp photos – regardless of whether the photographer is a professional or a hobbyist. Not only does the skill of the photographer, but also the technology inside the camera play a key role. maxon drive systems help to create lightning-fast images.

With its Leica S system, camera manufacturer Leica offers a unique combination of performance features for digital photography. It combines the image quality of a medium-format camera with the handling, speed and flexibility of a small-format camera. The lenses used in the Leica S system have a built-in dedicated processor for controlling the auto focus. The lenses are also available with a central shutter for maximum flexibility when using a flash. Besides the focal-plane shutter, which is integrated in the camera, the central shutter is one of two common designs. The central shutter is typically located at a “central” position in the lens assembly, between the optical lens elements. It consists of several blades arranged around the optical axis in a concentric pattern. When the shutter release of the camera is pressed, the blades snap back from this axis synchronously and let the light fall on the sensor.

With SLR cameras, the central shutter first closes after the shutter release, because all the settings were made with an open shutter. The mirror swings up, then the central shutter opens for the duration of the exposure before closing again. Finally, the mirror swings back into the path of light, and the shutter opens. Even though it employs the classic solution of mechanical springs for the efficient storage of potential energy, the central shutter is a piece of cutting-edge technology. The tensioned-spring principle contributes significantly to the extremely compact dimensions.

Small motor for high tension
The springs are tensioned by a specially developed maxon motor with a high-precision overrunning clutch and release their stored energy to activate the shutter blades when the shutter release is depressed. A specially constructed solution prevents the blades from rebounding when the shutter is opened or closed. A microprocessor-controlled pawl and ratchet mechanism controls the shutter cycle via two electromagnetically activated plungers.

The gear motor of maxon motor is used for tensioning three springs that store the energy for the central shutter. A maxon A-max 12 motor is used as the base motor. The gearhead is an all-new development and is adapted to the available space. This presented a special challenge to the gear motor in the central shutter of the Leica lens. What was needed and developed was a very compact, enclosed and sealed custom version of the gearhead with perpendicular power transmission to toothed gear of the central shutter through a crown gear, for a life span of more than 100,000 releases.

Right Angle Spiroid Gear at MD&M West 2015

Designed to achieve maximum torque with minimal space. maxon precision motors introduces right angle gearheads designed to be configured with maxon’s 22mm and 32mm dc motors. These compact, lightweight and high torque gearheads were developed to transmit power at 90deg in the smallest possible form factor.

DC drives made to order: The selection just got bigger

maxon motor’s successful X drives program is being expanded to include a new motor size and different planetary gearheads. Putting together the right DC drive assembly online has never been so easy.

maxon’s revoluntary X drives of DC motors and gearheads offer customizable choices that are easily and quickly configured online. They are stronger and more efficient than other drives currently available. The product line is now being expanded to include the DCX 12, a micromotor with a diameter of 12 millimeters to close the gap between the DCX 10 and the DCX 14. It is available with precious metal brushes as well as various options for ironless windings and bearings. The matching planetary gearhead (1–4-stage) is also now available.

New versions of configurable planetary gearheads

What’s more, existing gearhead sizes can now be obtained with several new reduction ratios: GPX 14 (new 3 and 4-stage), GPX 16 (new 4-stage), and GPX 37 (new 1 and 2-stage). The planetary gearheads with the sizes 14, 26, and 37 millimeters are also available in ceramic, reduced-noise-level, and reduced-backlash versions.

All the new products are now available in the online shop. Customers choose the desired motor, the matching winding, brushes, and shaft length, as well as the gearhead and encoder. The order is ready for shipment after just 11 days. You can find more at: xdrives.maxonmotor.com.

Right Angle Spiroid® Gear

Designed to achieve maximum torque with minimal space

maxon precision motors introduces right angle gearheads designed to be configured with maxon’s 22mm and 32mm dc motors.

These compact, lightweight and high torque gearheads were developed to transmit power at 90deg in the smallest possible form factor. The Spiroid® technology incorporated in the gearhead design offers a number of performance benefits:

  • Extremely high torque transmission
  • High stiffness / Low deflection with large applied loads
  • Back-drivable (4:1 ratio) & Non-back drivable (31:1 ratio) versions
  • Compact size
  • Low backlash
  • Up to 3:1 “gear teeth” contact ratio
  • Quiet operation
  • High Torque to Space Ratio (HTSR) technology

The 22mm and 32mm right angle gearheads are available in either a 4:1 or 31:1 ratio, which may be mounted directly onto many of maxon’s brushed/brushless motors OR configured with different ratios of maxon’s GP22 and GP32 planetary gearheads. This results in a wide range of achievable gear reductions. The motor and gearhead combinations are ideally suited for a variety of applications particularly where an output shaft perpendicular to the motor axis is desired.
