More choice from maxon: sterilisable brushless DC motors

Maxon now offer more sizes in their sterilisable range of brushless DC motors, gearheads and an all new encoder.

Now available in a 13mm diameter is the brushless DC motor (ECX SPEED range) with accompanying planetary gearheads (GPX 13 SPEED) and the first of its kind sterilisable Encoder (ENX 13 EASY INT). All fully configurable, sterilisable and optimised for high speeds and low vibration output, making them perfect for demanding speed and positioning control tasks in surgical applications.

A stand-out feature of the sterilisable encoder is the chip used for generating the commutation signals in the Hall sensor version. When coupled with the brushless DC motor ECX SPEED 13 it facilitates extremely precise commutation and reduces heat. The encoder can be integrated within the motor to optimise costs and assists in applications with tight space restrictions. The DC motor combination can be configured online and ready to ship in 11 working days.

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.

Fast, reliable DC motors for ice-core drilling in the Antarctic.

Ice-core drilling is nothing new. But maxon motor developed a DC motor gear combination that can drill up to eight times faster than existing drilling, 600 metres below thick ice.

Conventional ice-core drilling takes a long time. The 3.4km deep hole at Dome Concordia in the Antarctic took five years to complete. 800,000 year old ice was retrieved which, up until now is the profoundest look into the history of the Earth’s core.

Using maxon motor DC technology, several small drill-sites of approximately 600 meters are bored to ascertain the correct position to deep-drill. The thickness of the ice and the geothermal heat indicate if it is worth drilling deeper to yield useful scientific results. A process that would previously take two months to complete, but now with maxon DC motors takes seven days.

The DC motor gearhead combination selected for this task was an off-the-shelf, maxon EC 45 250 Watt motor combined with a GP 52 planetary gearhead. Some modifications were made however the basis of the selection was the high power and high torque, with the ability to vary the speed of the motor at a constant torque. Most importantly, the DC motor had to fit into a very compact space within the drill and withstand extreme temperatures.

DC motors steering the rear wheels of race cars.

Maxon actuators, DC motors, gearheads and encoders help to improve the handling and overall driving stability of a race car through rear wheel steering, with up to 3 degrees transfer per side.

A maxon supported Young Engineers Student project is developing mechatronics for steering the rear wheels of a race car. At the heart is a maxon spindle drive (linear actuator) that converts rotational movement into linear movement. Fitted with an EC-4 pole brushless DC motor to provide up to 200W of power, GP32 planetary gearhead for torque and two maxon EPOS2 position controllers with HEDL encoders to set the steer angle of the wheels. The maxon drive system is connected to the cars internal controls to calculate the desired steer angle.

The main issues for the engineers were lightweight, small components, with enough force to set the required steer angle and trustworthiness of the components to work reliably without fail.

22mm High Speed Brushless DC gearmotor in DRS system

When you only have 0.2seconds to move your load maxon motors and gearheads are required.

In 2016 the Academic Motor Sports Club Zurich set a world record for electrically powered vehicles by accelerating to 100km/h in 1.513s. Maxon motors are used in the vital race car Drag Reduction System (DRS). The maxon 22mm Brushless DC motor and high powered 22mm planetary gearhead drive rear airfoil. Rotating 165˚ in 0.2 seconds means the gearhead had to withstand very high forces.

IP rated brushed and brushless DC motors.

maxon motor planetary gearheads fitted with rubber sealed bearings when an IP rated motor or motor and encoder combination is selected.

maxon standard brushed motors of 50mm 200W and 65mm 250W sizes in 12V, 24V and 48V have the option of either an industrial housing to seal the unit in harsh environments or a 500 and 1000cpt 3 channel digital encoder in a sealed industrial housing. This standard option is also available on 45mm 250W brushless motors and 60mm 400W brushless DC motors. All motors have an extended range of planetary gearhead options which when ordered in conjunction with a sealed motor are automatically upgraded and supplied with sealed bearing assemblies. The motors do not require airflow and as such also have been supplied with custom coatings to suit specific environmental conditions. Sealed motor housings are available with axial or radial cable exits and custom uniform diameter designs.
