Custom DC motor for maximum power density

New Brushed DC motor deisgn450px

New brushed DC motor design from maxon motor.

maxon motor Australia have configured a combination of brushed DC motor, planetary gearhead and digital incremental encoder with completely customised features for a prominent medical manufacturer and have produced it in 11 working days.

An interactive 3D model of the entire assembled combination showing all modifications and final production part numbers can now be generated within an hour of specification request along with data sheets showing the working points of the application. The new process eliminates large amounts of traditional internal procedures, with the robotic production line and parts procurement all linked together with the new design tool. The new motor pictured below shows a unique stepped planetary gearhead that uses a 26mm diameter on the high speed input stage and a 32mm on the high torque output stage. Focusing the wear and strength attributes by placing components specific to their role also increases the motors power density. In order to allow for the full use of shaft length that is tailored for the application, a new process of laser welding the inner race of the output bearing directly to the shaft material has been used over the traditional methods of c-clips and shaft collars. This is also naturally stronger than glue and press fit methods. The motor is capable of producing over 10,000rpm and the gearhead up to 12Nm with ratios to 1526:1. Zero cogging and linear characteristics combined with new encoder resolutions up to a staggering 65,536cpt open new position control possibilities for automation, tool and robotics applications.

DC motors in blood analysis machines

 

Montage convoyeur medical, entreprise MDP (Maxon Motors) Neyron, Ain.

High-tech machines analyse human blood samples and detect coagulation disorders. Maxon motor France supplies the DC drives as well as builds entire conveyor modules especially for a customer.

Analysis devices in laboratories and hospitals run 24/7, autonomously pipetting samples to deliver quick results. Such industrial automation equipment must work with high accuracy and reliability. This in turn places high demands on all components of the machines.

Stago is a French company that specialises in analysis instruments for haemostasis diagnostics (for testing blood clotting). Maxon DC motors are found in Stago’s StarMax machine. A fully automated analysis system, the StarMax is equipped with a three-axes robot with space for 215 samples and 1,000 test containers. Working autonomously the machine checks results, compares them and monitors the processes.

There are several varieties of maxon’s brushed A-max DC motor combined with planetary gearheads, that are used for the movements of the rack. With varying diameters between 16 and 26mm, these DC motors were selected for being highly dynamic and easy to control. The DC motors have an ironless rotor and are manufactured autonomously giving them an attractive price-performance ratio.

New! Maxon release the first sterilisable encoder.

 

ENX-EASY-13-Sterilisierbar_450px

maxon motor have unveiled the first sterilisable encoder for brushless DC motors. This will create many opportunities for advances in medical technology.

The first steam sterilisable encoder has been released by maxon motor. The ENX EASY is available in two versions, as an incremental (1024 CPT) and an absolute version (4096 CPT). It can be integrated into suitable motors without increasing the length. The encoder has allowed maxon to create the first sterilisable drive system with brushless DC motor, gearhead and integrated encoder.

Ideal for demanding medical / surgical applications where speed and positioning control tasks are performed. Available with ball bearings or in a ceramic version. The encoder delivers high speeds, extremely precise commutation, low vibration and reduction of heat build-up. To optimise costs and space restrictions, the encoder is integrated in the brushless DC motor.

New! Brushed DC micro motors and gearheads in 6mm and 8mm diameters.

6mm 8mm GPX DCX ENX

For applications requiring a DC micro motor that is robust, powerful and delivers high performance.

maxon have released two new brushed DC micro motors available in 6mm and 8mm diameter as part of their DCX range. The DC motors have a robust design with maximum power density from the high-performance neodymium magnets.

Also available are matching gearheads, the planetary gearhead 6mm and planetary gearhead 8mm, as well as two motor controllers, the ENX 6/8 OPT (optical) and ENX 6/8 MAG (magnetic). The matching planetary gearheads are welded directly to the motor and offer reduction ratios of up to 1000:1. Both are able to transmit short-term torques of 60 and 150 mNm respectively. The motor encoders are available in two versions for each diameter and work with voltages as low as 3V, therefore making them highly suitable for medical devices. The encoders come in a magnetic version and for magnetically sensitive applications, the optical encoder is available.

These micro motors are configurable online and available for dispatch in 11 working days from date order placed.

Maxon building a new site focusing on innovation and DC motors for medical devices

airshot_headquarters_maxonmotor_ag3_450px

 

An investment of CHF 30 million will see a new center for innovation, R&D and production of maxon’s smallest DC motors and drives for use in medical applications.

At their headquarters in Sachseln, Switzerland, maxon motor are building a new site with construction commencing February 2017 and due for completion by the European Summer of 2018. Keeping in line with maxon’s environmental policy, the new build will have solar installation generating 180 MW hours of electricity per year and a habitat for local plants and animals.

With a focus on the medical industry, to meet future demand projections the maxon medical division will double in size. Producing the successful micro-motor (4mm in diameter) as seen in surgical robots, insulin pumps and medication delivery systems, the demand for this field has grown enormously with the advancements in technology. To meet the strict medical quality mandate, the production area will be equipped with clean rooms including a biocompatible room.

The new facility will also house research & development, complete drive systems in mechatronics and Industry 4.0 networking of production. “The new Innovation Center is a move to strengthen our Swiss headquarters in order to become stronger internationally”, says maxon CEO Eugen Elmiger.

Innovation, DC motor technology and the medical industry.

maxon-dc-motors-in-medical-applications450px

The number of worldwide medical patents filed in 2015 was more than twelve-thousand. The term “innovation” certainly applies to this industry.

In the field of medical technology, surgeon’s tools and machines are becoming smaller. Robotic assistance is commonplace in prostate surgeries. Minimally invasive surgery, surgical tools that can reach sensitive and in-depth parts of the brain once considered too high-risk, are being explored. Machines that aid faster patient recovery times and robots that assist in rehabilitation. Maxon motors are at the forefront of medical technology, working along-side Universities, start-ups and multi-national corporations. Medical applications that have maxon DC motor technology and expertise include the da Vinci Robot, wheelchairs that can climb stairs, aortic pumps for heart patients, implantable dosage systems, robotic exoskeletons, surgical tools and prosthetics.

Maxon DC motors for specialist medical equipment in a bio hazardous environment

dc-motor-right-angle-gear2

An Australian company designed and manufactured specialist equipment for use in a mortuary.

An Australian company has designed and manufactured a specialist trolley for use in a mortuary. The design incorporates matching motor and gearbox technologies from maxon partners KAG and Apex Dynamics. The robust DC motor manufactured by KAG was a perfect match with the Apex Dynamics high precision Spiral Bevel Gearbox. Unique considerations for the gear-motor combination such as IP ratings, axial and radial loadings, and corrosive environment were important in this specialist application. The gearbox features a high mechanical rigidity with a single piece construction, precision ground gear sets to optimise efficiency, low backlash and were sealed and lubricated for life.
