Multi axis brushless DC motor position controller system

From two to eighty axis – maxon motor release a revised, versatile multi axis motor position system.

Need an eighty axis position control system? Well let’s face it, not everyone does. Though more often than not, in today’s increasingly sophisticated world of motion systems three and four axis systems are required. The trouble for motion control suppliers is being able to meet customer demands for motor position control systems with seemingly infinitely variable requirements.

Three axis controller systems in the past were very common but when you needed to control four motors there were two servoamplifiers paid for but not used. What made this industry standard even more inefficient was that inside the box for these motion controllers was simply three separate motor control units connected on a Bus system. This describes the problem that maxon multi axis system has solved.

Developed as an eleven axis motherboard with snap-apart individual drive segments. The exact number of motor axis can be easily configured simply by separating the required number of drives and jumping both the power and communications along the board. It is an incredibly simple though effective solution that has now been tested and proven in every combination. The most notable application is an eighty axis motor control system for a complex food handling production line.

Technical features include: CANopen control, Interpolation Position Mode, 6 digital inputs and 2 analogue inputs per axis, current regulation and a wide voltage input.

Outrunner or Inrunner BLDC motor?

New BLDC design has the advantages of both outrunner and inrunner brushless DC motors.

Outrunner motors offer many advantages, the biggest of them being the maximised distance from the shaft centre to the flux gap of the motor creating a larger lever arm effect from the torque production location to the axis. The larger diameter of outrunner motors therefore gives typically very good torque characteristics. There are also disadvantages of BLDC outrunner motors. The externally rotating rotor and static internal stator is a particular concern in any equipment that is operating near people or in harsh environments. This new design offers an “internal external rotor” that is contained in a aluminium or optional sealed stainless steel motor housing. There are other additional advantages for the new design. The design contains a unique internally mounted 4096cpt incremental encoder and can be assembled with high torque ceramic planetary gearheads, producing a positioning drive system with a slow motion high torque focus. Applications in process control, valve actuation and industrial machinery are particularly suitable for this new motor.

e-mobility is changing our world.

The latest issue of maxon’s driven magazine looks at developments and trends in e-mobility.

50 years ago, it wouldn’t have been dreamed of that a family could go on a trip in their car without burning a drop of fuel. Or that inexperienced cyclists could tour vast mountain ranges. Or that robots pull weeds, not humans. These are three, of many, examples that show the influence of electric drive systems on our daily lives and our mobility.

In addition to e-mobility developments, readers get an insight into the battery development at maxon and meet a friendly superhero with a disability. For inquisitive minds, there is an in-depth technical article about inductance in iron-core DC motors.

Brushless motor with encoder and gear. Customised to perfectly match critical servo motor requirements

Requiring up to 22Nm of intermittent torque with only a tiny amount of available space, only maxon motor could custom build the perfect solution for this application. The brushless DC motor contains an internal 1024cpt encoder and is only 22mm long.

Outrunner style pancake motors have an external rotor which offers both advantages and disadvantages. The brushless DC motor has the rotor magnets mounted on the outside of the stator giving the motor more available torque via the additional distance between where the force is produced and the shaft. Essentially, more leverage. However, having an external rotor leaves the rotating mass exposed to the operating environment where it could potentially be impacted upon and create imbalances on the motor.

maxon motor were able to combine a unique combination of a flat brushless DC motor with an internal 1024 count per turn encoder with a ceramic planetary gearhead to meet a customers’ application requirements, though the exposed rotor was a concern for the engineer. By re-designing the front mounting flange of the motor, maxon were able to build a custom rear cover for the motor to protect it and stay within the maximum 43mm available diameter. This must be designed around the thermal requirements of the motor when working in the application environment under the specific loads and duty cycles.

Customisation processes like this for specific requirements then become available for other applications and eventually catalogue components. The motor is now available for system voltages from 12V to 48V with internal encoders from 256 counts per revolution to 2048 counts. There is a ventilated version for high power density, a standard version and an enclosed version.
