photo450pxDC motor with right angle gear and inline gear combined © 2016 maxon motor

A unique DC motor and gearhead combination developed for an Australian customer providing solutions for robotic rehabilitation.

When high power levels and tight space constraints are required, maxon motor tailor a solution. maxon motor Australia recently developed this motor and dual gearhead design for a robotic exoskeleton application for rehabilitation of children with disabilities. Gearing with the high efficiency level of over 98% on the right angle transfer has been achieved with the use of an sealed, oil filled helical bevel design. A custom adaptor section has then been specifically manufactured to affix a 52mm 113:1 ceramic planetary gearhead at the helical gearbox input. The use of ceramic components within the planetary gearhead increases the lifespan typically by three times compared to traditional steel planetary gearboxes. The 50mm diameter 48V 200W DC maxon motor also achieves the high efficiency of 94%. maxon motor are renowned for high efficiency DC motors but the careful design and selection of the drivetrain components in this gear motor system has set new benchmarks. A common 500cpt incremental encoder has been fitted to the motor back shaft and when combined with the gear ratio and maxon motor control software quad counting, gives a system positioning capability of 0.001 degree. Such a fine positioning capability is also only possible with the assistance of the patented maxon motor rhombic coreless winding that gives a completely smooth motion void of any mechanical detent or magnetic cogging.

maxon Robotics feature: Part 5

Lab_Robotics_Pipette_machine195px

Laboratory robots: the maxon motor drive solution.

For speed and position-critical dispensing actions, maxon offer a DCX motor with high overload capacity, small in size, linear curve for minute control and high CPT.

One special type of robot found in a laboratory is the Pipetting machine. Used by small molecular biology labs for flexible liquid handling through to large scale active-ingredient screening by multinational pharmaceutical companies, the one common trait of these machines is the speed and position-critical dispensing actions. Handling hundreds of samples all at once, some equipped with numerous pipetting heads, the speed of these machines is increasing and the fluid quantities dispensed is becoming smaller and smaller. Essential to this is a highly dynamic and precise drive.

The maxon motor drive solution

Especially suited to this task offering very low instances of inertia and ironless windings with falter-free movements. The brushed DCX motor. Low noise output. Configurable to a planetary gearhead and encoder – the GPX 12 and ENX 10 EASY Encoder. This combination can be configured online and shipped in 11 days. The motor has a high overload capacity, is small in diameter for space critical machines, has a linear curve for minute control characteristics and a high level of precision up to 1024 counts per turn.

Brushless DC motors drive a wheelchair that will climb stairs.

Climbing stairs at a speed of one step per second. Powered by two maxon brushless DC motors this electric wheelchair is safe, maneuverable, fast and easy to operate.

This remarkable wheelchair is widening the landscape for those who rely on wheelchairs for everyday use. University engineers wanted to remove the hurdle that stairs present for a wheelchair user.

Upon approaching a set of stairs, the person will select a function on a touch screen. With sensors and cameras that measure the incline of the stairs, the wheelchair automatically turns around and reverses up the stairs. The person stays upright at all times and is stabilised by the design of the caterpillar wheels.

The wheels and the caterpillars are equipped with two maxon brushless DC motors fitted with ceramic gearheads. The modified gearheads give a longer service life. Selected for their durability, precision movements, quiet operation and lightweight at 3.2kgs the brushless DC drives unite two motion principles in one. Upon reaching the top of the stairs, the chair stabilises and retracts the caterpillar wheels under the chair thus continuing the journey on two wheels. Controlled by a maxon EPOS2 70/10 controller, the digital positioning of the EPOS2 ensures perfect control for both brushed and brushless DC motors.
