When performing microsurgery using the HeroSurg robot, surgeons have an added sense of touch. Fitted with two maxon motors, the DC RE25 & EC-max, and EPOS controllers.

Sat behind a computer or even thousands of kilometres away, using the HeroSurg robot a surgeon is able to operate with specific precision and a new sense of “touch”. Through the use of ground-breaking technology the HeroSurg gives Surgeons a “feel” for the tissue they are working on. Primarily used for laparoscopic and keyhole surgery, this means less aggravation on healthy tissue leading to improved healing time, less blood loss & risk of infection and a shorter stay in hospital. The patient’s overall healing time is generally lessened too.

The HeroSurg is fitted with maxon RE25 and EC-max22 motors. The RE25 DC motor is high-quality, both compact and powerful, equipped with powerful permanent magnets. The centerpiece of the motor is the ironless rotor. The EC-max is a robust, brushless DC motor with speeds up to 20,000 rpm.

High precision drives specialist, maxon motor introduces high-end solutions for underwater applications.

Today’s modern technology must be equipped to withstand extremely harsh conditions found deep in the ocean. These conditions often include high pressure and high oxidation levels. maxon motor as a world leader in drive systems has worked closely with research institutes and universities to provide solutions that meet the many demanding challenges for electrical and mechanical components required for underwater systems.

Electrical actuated underwater vehicles like ROVs (Remote Operated Vehicles) and AUVs (Autonomous Unmanned Vehicles) require drives which are light weight, highly efficient and compact design. maxon’s program of aquatic solutions offer these features and much more. The core element is a motor-gear combination based on a brushless DC-motor and a planetary gearhead. These underwater drives are designed with a high quality polymer housing to ensure protection against the harsh underwater elements.

maxon’s MT-30 thruster is pressure tolerant up to 6,000 meters with oil compensation. The propeller is modified for low noise operation. Other features include: Maximum bollard thrust of 10kgs, Voltage of 27 and weighs slightly over 900gms.

Modern robotic equipment, a lot of hard work and maxon DC motors.

maxon DC motors can be found in robotic aids, in some cases assisting incomplete paraplegic people to walk again.

Swiss company, Hocoma, is making huge in-roads using robotic equipment to assist in the rehabilitation of people with neurological movement disorders, stroke and incomplete paraplegic patients. There are four different types of equipment that assist with muscular strengthening exercises, exercising joints, sense of balance and improving circulation. In some cases, the equipment has assisted some people to start walking unaided again.

Brushed and brushless maxon DC motors and controllers can be found in all four of Hocoma’s robotic devices. The brushed maxon RE-40 DC motor was selected for its powerful density, ease of control, efficiency level of more than 90% and robust design. The motors ironless rotor delivers low inertia packed with a powerful punch. Also utilised are the maxon brushless EC-60 flat / pancake motors, chosen for their small and compact size and ability to deliver high speeds.

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.

Now available for online configuration maxon motor Australia release new sizes of DC motor and planetary gearhead.

Following from maxon motors release of the new ECX DC motor (read about it here), now available are new sizes of the high speed brushless DC motor and planetary gearhead. A complete DC drive system can be tailored to individual demanding applications by adding the EPOS powerful motor controller.

New sizes available include the ECX 8mm and 22mm diameter (in both Medium and Long versions) and eight variations of the GPX planetary gearhead in sizes ranging from 12mm to 26mm.

The benefits of the new ECX range of DC motors include extremely high speeds, low noise, sterilisable and lightweight for applications with compact space constraints.
