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).

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.

More versions, more power the new DCX motors and GPX gearboxes

New additions to the maxon family of X drives

Now even stronger, more efficient and with yet more combination options: There are new additions to the maxon family of X drive products. Several long versions of brushed DC motors, with higher torques and more power, are being added to the product range, together with matching planetary gearheads. Each of the 3-stage versions can now be combined with the next smaller motor. This saves space, weight and costs.

Two years ago, maxon motor introduced a new generation of brushed DC motors – the maxon X drives. These are extremely powerful, easy to configure online, and ready for shipment within 11 days. Now, four more motor sizes are being added to the existing p

ortfolio. The 14, 16, 22 and 26 mm diameter models are now each available in a long version (L), which offers higher continuous torque and higher continuous output power.

At the same time, maxon motor is introducing four new GPX planetary gearheads, in the sizes 14, 19, 26 and 37 mm, compatible to existing products in the program. These gearheads are designed with scaled gear stages. Each of the new 3-stage gearheads can be driven with the next smaller motor. This brings many advantages, as the resulting drive system is smaller, lighter and more economical.

That’s not all, starting immediately, the existing GPX 16 and GPX 32 models are available in various versions and can be equipped with ceramic axles to reduce wear. Customers looking for a particularly low-noise gearhead have the option of choosing plastic planetary gears.

maxon also expanded the encoder portfolio. The new ENX 16 Easy absolute encoder is available as an SSI or BiSS-C version, according to the customer’s requirements.

All new products are available in the online shop starting immediately. They can be easily configured together with the other maxon X drive products: Customers select the desired motor, the matching winding, brushes and shaft length, as well as the gearhead and encoder. The configured product is ready for shipment in 11 days or less. For more information, go to dcx.maxonmotor.com.

maxon’s EC-4pole 32 HD with planetary gearhead

This 480 W motor can withstand 200 °C, 1000 G, -5000 m and 1700 bar.

maxon’s EC-4pole 32 HD

The Heavy Duty Motor EC 22 HD, innovation of the year in 2010, has now been joined by a larger and more powerful version. The new, electronically commutated EC-4pole 32 HD motor has all the features of the award-winning 22 mm motor. It is designed for extremely rough operating conditions, particularly applications in deep drilling.

Deep drilling technology (called “downhole drilling” in the field of oil and gas exploration) makes it possible to recover oil and gas from depths of more than 2500 m. By combining deep drilling with directional drilling (dynamic position alignment of a bore in the earth), previously unreachable oil reserves are being opened up, with drilling depths of approx. 5000 m and drill lengths of up to 11000 m. The development of specialized electronics and drives has made it possible to better monitor and control many functions across the entire drilling process. For instance, it is now possible to dynamically measure and adjust the position of the drill head during the drilling process. Diverse deep drilling tools also use hydraulic valves or flaps that are operated by electromechanical drives. The temperatures and pressures at these depths, combined with the strong vibrations that occur during the drilling work, present unique challenges for the use of electronic drives.

The different versions of the EC-4pole 32 HD are designed for operation in air or in oil (flooded in hydraulic oil). The power rating depends on the surrounding medium and amounts to 220 W in air and, due to the much higher heat flow, 480 W in oil. They are designed for ambient temperatures of more than 200 °C and atmospheric pressures of up to 1700 bar. The Ø 32 mm motors must also be able to withstand vibrations of up to 25 grms as well as impacts of up to 1000 G (1000 times the acceleration due to gravity at the earth’s surface). As an example, a Formula 1 vehicle is exposed to approximately 2 G and fighter jets are exposed to approxi-mately 13 G. The motors feature high efficiency (up to 89% in air, more than 80% in oil), making them ideal for use in battery-operated applications. With their detent-free running properties, they have excellent control characteristics and are suitable for high-precision positioning tasks in outer space, even at low speeds.

The EC-4pole 32 HD is ideal for use in environments with extreme temperatures, subject to high vibration, or under ultra-high vacuum. This means the motors can also be used in aerospace applications, e.g. for gas turbine starters, for the generators of jet engines, for regulating combustion engines, or for exploration robots. For the use of the motor in conjunction with a gearhead, maxon offers the GP 32 HD, a powerful and robust planetary gearhead.

NEW configurable DC motors and gearheads

maxon motor’s  DCX series is being expanded with two new DC motors. The GPX 22 gearhead is now also available in a version with reduced noise level and with ceramic axes.

In addition to the maxon DCX 10L, a shorter version is now also available, the DCX 10S. Like all motors in the DCX series, this brushed DC motor excels through high power density and low vibration. The DCX 10S exceeds the 1 mNm threshold during continuous use. With its mechanical output power of up to 1.4 W in a 10 mm diameter, it is a real powerhouse. Regardless of whether this electric motor is equipped with sintered bearings or ball bearings, the DCX 10S features extremely quiet operation running below 35 dBA*.

The DCX 22L is the new longer version of the DCX 22S. This brushed DC motor, with a diameter of 22 mm, even outperforms the existing maxon RE 25. With the DCX 22L the same power is achieved, yet with 30% less volume and weight. The GPX gearhead series is also being expanded with two new variants:

The GPX 22C is an optimized version of the GPX 22. The improved performance data and life span were achieved by using ceramic axes. Although the same in size, it provides approximately 20% higher torques. Another new member in the maxon GPX family is the low-noise version of the GPX 22. The GPX 22LN has special plastic planet gears in the input stage that reduce operating noise, which mainly occurs in the input stage, by about 5 dBA*.

Ready in 11 days.
All configurable DC motors, gearheads and sensors of the maxon DCX program can be ordered online. After only 11 working days, the drive systems are ready to be shipped from Switzerland. Detailed product data can be viewed online immediately, and 3D data for the configuration is available for downloading. Discover more at dcx.maxonmotor.com.
