Custom DC motor for maximum power density

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

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.

Brush massage system for your shower.

Maxon DC motors are found in a massage system that fits to nearly any shower, converting your everyday shower into a wellness experience.

The focus of a Swiss company’s new massage brush system is designed as an overall experience incorporating massage for tired/ sore muscles, brushing away dead skin cells and supporting blood circulation. The system is a rotating brush that moves horizontally and vertically. It automatically travels up and down a rail, with the option to program a personal massage and using a remote control.

Battery operated, the brush rotation is powered by a maxon DC motor, A-max 32, combined with a planetary gearhead, GP32. For the system’s height adjustment, there is a brushed DC motor, DCX 22S, fitted to a GPX 22 planetary gearhead. The DCX combination motor and gearhead can be assembled online using maxon’s online configuration portal.

Overall, the conditions in a shower – steam, cleaning products, water and humidity – are no problem for maxon’s reliable DC motors and Planetary gearheads.

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

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.

Zero backlash brushless DC motor and Harmonic Gearhead combination with internal encoder.

DC motor and harmonic gear zero backlash450px

New levels of torque and position capability are now possible with the development of adaptive hardware for maxon low profile brushless DC motors and harmonic planetary gearheads.

Pictured is a combination showing the maxon brushless DC 70W 24V motor, 2048 counts per turn internally integrated encoder and the new harmonic light weight low profile zero backlash gearhead. The gearmotor assembly increases the torque and reduces the size of previous solutions using planetary gearbox technology. The output capability is 19Nm repeated and 31Nm intermittently, which is ground-breaking for a combination just 55mm diameter and 59mm long for all three components. Having and internal encoder and a zero backlash gear makes the unit ideal for robotic joint and positioning applications in industrial automation, process control and also for precision laboratory and scientific equipment.

New motion controller design for speed and position control of DC motors

maxon motor’s new motion controller for DC motors is very small indeed. Just 17g and 39mmx54mm the position controller can also control both brushed DC motors and brushless DC motors (BLDC motors).

Available on request is the newest version of the successful EPOS DC motor control modules, the EPOS4 24/1.5. The tiny dimensions of the controller belie it’s capabilities. It retains the full motion control capabilities of much larger controllers including RS232, USB, CanOpen and EtherCAT communications onboard or via adaptor modules. Feedback from the DC or BLDC motor is achieved using either hall sensors, incremental encoders or absolute encoders. It can be used with current / torque control, closed loop speed control and position control. Designed primarily for use on 12V or 24V systems the controller is based on a very high PWM frequency of 100kHz for adaption with highly dynamic ironless and coreless DC motors that have low inductance levels. Current limiting, overcurrent, over temperature, under voltage, overvoltage and short cct protective functions are all included as standard. Free setup software for auto configuration and tuning of motors is supplied along with programming examples for PC, PLC, Labview and Linux environments. IEC61800-5-2 based Safe Torque Off (STO) also makes the controller suitable for use in critical applications such as manufacturing processes and collaborative robotics.
