Taunton, MA — Motion Control Products – Every Mars drive from maxon is based on a catalog product and is modified for the specific mission. That’s because the DC motors, gearheads, and encoders face brutal conditions during liftoff, the long journey through space, and the mission on the Red Planet. In this blog, I will talk about the properties a drive needs to have to qualify for a journey to Mars.

motion control - electromate logoVaughan, Ontario, Canada — Motion Control Components — Introducing Dual Absolute encoder versions of the FHA-C mini actuator. Featuring BiSS-C Harmonic Drive fha-24v-002bi-directional communication for both encoders. The dual encoders are incorporated in essentially the same package size as the long-standing FHA-C mini single incremental encoder version. Without increasing the size, the dual absolute encoder offers single turn absolute position at the output, without the need for battery back-up. Panel mount connectors come standard, and customers can choose between 4 exit options.

The FHA-C mini Series is a family of extremely compact actuators that deliver high torque with exceptional accuracy and repeatability. The actuator combines a high precision Harmonic Drive® gear component with a pancake brushless servo motor. A single turn 14 bit (16384 cpr) gear output encoder has been integrated along with a single turn 14 bit (16384 cpr) motor input encoder providing a true absolute encoder that does not require a battery within 360° of rotation of the output. Typical multi-turn encoders monitoring the motor input shaft require a battery to store the current position when power is lost to the system; however, the dual absolute encoder overcomes this need. In other words, No Battery Required. When power is restored the actuator knows its position.

Features include:

  • Zero backlash
  • Incremental, Absolute or Dual Absolute Encoder
  • 24VDC winding
  • High-torque/weight and torque/volume ratio
  • Optional flex-rated cables with sealed connectors

Motion Control – Maxon Gearheads – Great power in Compact Form!

Motion Control – Maxon Gearheads – Great power in Compact Form!

motion control - gearhead cutawayMicro gearheads from maxon with improved efficiency.

 


motion control - maxon motorsTaunton, MA — Motion Control Products – Maxon has developed a unique upgrade in the form of a new product series for its standard micro gearhead: A wide range of performance improvements offer new opportunities.

The first ideas for the UP-gearhead were inspired by ESA’s Mars project ‘ExoMars’ and NASA’s ‘Mars 2020’ project, where there was a need to ensure the highest possible availability even in extreme environmental conditions.

This also directly affects further parameters of the drive system: Given the same input power, ie. using the same motor and the same motor control system, the gearhead can deliver 30% more torque. Or put another way: the same output power will require 23% less input power for the drive. This results in longer potential action time until the next charge cycle, particularly for battery-driven applications.

As a result of the reduction in the input power required, the used motor can in addition be operated at a more favorable operating point. This factor also improves the efficiency of the motor, and with it the whole drive system.

As an alternative, smaller and/or lighter motors and electronics can be used, with advantages not only in terms of weight but also in terms of cost.

motion control - gearhead groupSignificantly longer gearhead service life: as outlined above, friction in the planetary wheel – axle system could be considerably reduced. At the same time heat generation from operating the drive is noticeably reduced because there is less friction power. Particularly in applications where temperatures should not exceed a certain level (example: medical power tools), there is improved power output.

The durability of the lubricant plays an important part in terms of wear and tear on the gearhead’s mechanical components. The greater the thermal stress, the more quickly its lubricating properties are lost, and the earlier and more serious the abrasive behaviors in the mechanical system. The abraded metal particles also lead to an agglutination of the lubricant, potentially resulting in a breakdown in its lubricating action.

If the heat feed is checked, then in otherwise identical operating conditions a longer service life can be achieved. This effect is an outstanding feature of the GPX UP: the service life is 5 times greater compared with similar traditional maxon gearheads and when compared to competitors’ models currently on the market it is 11 times greater.

As an alternative to longer service life, as a result of significant improvements in the torque to diameter ratio (power density), much smaller and lighter gearheads can be used.

The advantages of the new design are not only producing improvements in the gearhead specification’s individual parameters. Further new applications for the GPX UP gearheads can also be seen, in particular the so-called force-feedback appliations.

With these applications the advantages of the engineering of the GPX UP version come into play. The use of mounted planetary wheels makes smooth inverse rotation of the gearheads possible in normal operation and, if necessary, can provide operator feedback. Quantifiable and tangible mechanical feedback is in fact conveyed to the force and torque elements. To achieve this, the gearhead needs to be reversible, meaning the torque and changes to the torque which are in contact with the output side, need to be conveyed proportionally to the drive side.

The following example demonstrates this application: In electronic flight control (Fly-by-Wire), the pilot’s steering movements are not transmitted to the actuators mechanically or hydraulically, as in conventional systems, but electronically. But with this the operator initially loses all tangible feedback on their steering movements. With the deployment of a drive in the control column, the electronically transmitted feedback is mechanically conveyed to the pilot’s hand. Inverse rotation is particularly necessary in normal operation, because the additional drive installed should not hinder the movements of the control column.

motion control - gearhead applicationA similar process applies to the innovative surgery robots in the micro- and telesurgery range. Here it is also crucial that the operator receives direct and tangible feedback about the movements they have performed or healthy tissue that should be left untouched. Reversible drives are also in demand in plant construction. In setting mode the axles need to be movable from the output side, without current.

The new GPX UP models combine a range of important product advantages, such as: More power, more torque, improved efficiency, considerably longer service life, reduction in heat generation, less weight in the drive system as well as the additional reversibility function in multistate gearheads.

Taking only the first two factors into account, we might refer to them as ultra-power gearheads. But with the other properties listed here, we can easily coin a new title: ultra performace.

Ultra Performance GPX gearheads from maxon are already available in GPX22 UP und GPX32 UP diameters, and like all ‘X-series’ they are customizable and available to order online. The GPX42 UP version will follow in Spring of 2020. In addition, customizable gearheads in the Ultra Performance series are now available in sizes Ø 8 – 58 mm.
