Brushless DC servo motor position controller.

300 6mm diameter brushless DC motors.

Small brushless DC servo motors for prosthetics, rehab and haptics.

Pictured here is a recent shipment for an Australian customer of 6mm diameter brushless DC servo motors that are destined for use in a medical rehabilitation application. This motor gearhead and feedback combination features a high motor speed capability of up to 100,000rpm on very low 3V, 6V and 12V winding options. There is also the possibility to customise maxon’s coreless winding to suit the desired speed range. The 6mm diameter planetary gearhead can reduce the speed and increase the torque of the motor by up to 854 times. The motor is fitted with a hall sensor network for feedback that gives a state change every 60 degrees. Considering both the speed of the motor and the increased resolution from the gearbox reduction this equates to a high resolution control over the motor. Fitted with multiple stainless steel ball bearings the motor and gearhead offer high radial and axial load levels and the motor preloading controls excessive resonance at such high speeds. In each application the winding constants and the gearhead ratios must be carefully considered to best suit the application.

maxon motor Australia: new premises at Mt. Kuring-Gai, NSW.

maxon motor Australia will be an exhibitor at AOG 2015

The leading brand of electric brushed and brushless DC motors will be an exhibitor at the Australian Oil & Gas Exhibition held in Perth from March 11-13.

The annual Australasian oil and gas Exhibition & Conference (AOG) is the platform event for the Australian oil & gas industry. maxon motor is pleased to exhibit and display a range of EC 22 HD (Heavy Duty) electric motors – motors that run in oil at -55°C to 200°C / drops up to 100 G / depths of -5,000m / pressure up to 1,700 bar!

As the first manufacturer worldwide maxon motor launched its EC 22 HD – a specialised, yet standardised, electric motor for extremely harsh operating conditions as encountered deep underneath the earth’s surface – from depths beyond 2,500 meters. In conjunction with directional drilling it allows exploration of, so far, inaccessible deposits in drilling depths of currently about 5,000 meters and bore lengths of up to 11,000 meters.

Currently, electronics and the respective drives permit more sophisticated monitoring and control in various deep drilling tools, hydraulic valves and flaps that are operated by electromechanic drives. Challenging environments such as temperature and pressure conditions; and high vibrations emitted by the drilling process, have contributed to challenges encountered by electric drive motors for use under these circumstances. A response by maxon to this specialist situation has been the development of the EC 22 HD motor. The different variants of the brushless EC 22 HD motor were developed for the exceptionally high requirements in deep drilling technology. The electronically commutated motor resists even most extreme conditions in which “normal” drives call it quits.

AOG is expected to attract over 600 exhibitors from more than 20 countries, and draw more than 15,000 visitors, exhibitors and conference delegates from around the world to the Perth Convention and Exhibition Centre from 11-13 March, 2015.

For more information on the EC 22 HD motor please contact a sales engineer on + 61 2 9457 7477. For more information on maxon exhibiting at the AOG please visit the AOG website

Discontinuation of A, F and S motors

A, F and S motors are being discontinued in favour of the RE, A-max, DCX and DC-max state-of-the-art ironless DC motors

For some time now the ironless A, F, and S motors have no longer reflected the state of the art technology integrated in other maxon motors which means they can no longer be manufactured economically. Order quantities have decreased which has compelled maxon to discontinue these motors in the long term.

The motors were launched in the 1970s and 1980s, and they have played a key role in the success story of maxon motor for decades. A, F, and S motors will remain available to customers until the end of 2017 (last delivery no later than June 2018). Because of the sharp increase in production costs, maxon is not able to accept and process small orders after 1 April 2015, thereby introducing a minimum-order quantity.

Introduction of minimum-order quantity:          1 April 2015

Last order:                                                       December 2017

Last delivery:                                                   June 2018

With our RE, A-max, DCX and DC-max series, maxon motor offers a wide range of state-of-the-art ironless DC motors. Any questions can be directed to our Sales Engineers on + 61 2 9457 7477 who can assist with minimum order quantities and alternatives.
