16mm brushless DC motors now available online

All maxon 16mm brushless DC motors are available to order online & ready in 11 working days.

The 16mm diameter brushless DC motors (or ECX 16 SPEED) have been optimised for high speeds (up to 120,000 rpm). Depending on the application requirements, there are various versions of the DC motors available: Standard, High Power, sterilisable (up to 2000 cycles), sensorless or with Hall sensors, or with ceramic bearings for high speeds. The 16mm dia. brushless DC motors in Standard and High Power versions were released in November 2016, representing more torque and better efficiency.

Configurable online, manufactured in 11 days and with detailed 3D product data available call maxon motor Australia on tel. +61 2 9457 7477.

A first: complete sterilisable motor, gear and encoder drive system.

The first of its kind! Brushless DC motor (BLDC motor), Planetary Gearhead and a choice of incremental and Absolute encoder all assembled to order in sterilisable form.

This is the first time a sterilisable encoder has been offered and it opens up new possibilities for the medical automation, laboratory automation and dental fields. A full position controllable system that is sterilisable.

The new encoder will have the optional output formats of both incremental to 1024 counts per revolution or Absolute with a 4096cpt (12 Bit). In standard combination with high speed brushless motors in 13mm and 16mm diameter speeds of 120,000rpm are possible and power levels over 100W. The high input speed gearheads can be selected with the correct ratio so match the applications speed and torque requirements and are of a robust stainless steel laser welded construction. Medical hand tools and specialist tools for controlled environments will benefit from this new development.

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.

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.

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.

It is suitable for permanent magnet-activated motors plus encoders with a range up to 750 W continuous output power. maxon encoders allow accurate evaluation of the speed & angle position and form the framework for high-precision control loops.

Multi-axis control of DC motors.

Getting the balance right with mechatronic systems involves the focus on a whole system and using modular motor system components for successful integration.

The new educational website by maxon motor drive.tech showcases the latest technologies and applications in the advanced motion control world. Dr Urs Kafader’s new article explains the process of getting the balance right in the critical motion control application of modern prosthetics.

Artificial limbs have rapidly moved into the world of advanced mechatronics. The synchronisation of multiple DC motors, sensors, transmissions and processors has become decentralised. The DC motors in these systems are required to fulfil an increasing number of functions that could soon encompass every human (or animal) movement. As such a huge variety of dynamics within the DC motor are required and modularity of components becomes a powerful ally. Each motor in these dynamic multi axis coordinated systems can now be locally controlled with real time field buss communication with full interpolation.

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.
