Drive range expanded
Miniature drives for medical robots and multi-axis systems
Maxon is expanding its configurable drive range in spring 2020 - including with brushed DC motors, gearboxes and encoders from the ECX series. There are also new products in the micro segment for positioning controllers.
The ECX series is growing with the addition of the ECX Speed 4, a small powerhouse with a diameter of four millimetres that is set to establish itself in the medical technology sector in particular. The brushless DC motors are available in lengths M and L and achieve speeds of up to 50,000 rpm. The new GPX 4 C gearboxes, which are available in two-, three- and four-stage versions, are a perfect match. The pressure angle of the gearing on the GPX planetary gearboxes has been optimized, resulting in longer operating times.
The associated ENX 4 MAG incremental encoder expands the possibilities of the drive system, for example for use in surgical robots. MAG stands for magnetic. According to Maxon, the ENX 4 MAG encoder is a novelty on the market in this size. It uses the same magnetic operating principle as the slightly larger ENX 6 MAG and ENX 8 MAG versions.
With the market launch in mid-April, the new drive systems from the ECX family can be configured online and delivered within eleven working days, the manufacturer promises.
Controller with high power density
The EPOS4Micro 24/5 positioning controller in the Ethercat version is also brand new. The controller is based on the existing EPOS4 products in terms of functionality, operation, software and accessories. It is suitable for use with both brushed DC and brushless EC motors up to 120 watts continuous power. There are also extensive feedback options such as Hall sensors or digital incremental and SSI absolute encoders. The motion controller with its compact design is suitable for integration into single-axis and multi-axis systems, for example for small devices or robot systems.
In addition to the new Micro design, a compact, ready-to-connect three-axis positioning system will follow in summer 2020 with the EPOS4 Compact 24/5 EtherCAT 3-axis. The system, which is based on EPOS4 Micro, is intended to show how small and highly functional such multi-axis solutions can be. as
