New miniature drives for medical robots and multi-axis systems

04 May 2020

The range of configurable drives from Maxon is expanding with more brushless DC motors, gearheads and encoders from the ECX series.

The ECX series is growing with the addition of the Maxon ECX Speed 4. This tiny powerhouse with a diameter of only 4 mm is designed for use in medical technology. The brushless DC motors are available in two versions: M (medium) and L (long) and can reach speeds of up to 50,000 rpm. They can be combined with the new GPX 4 C gearheads, which are available as two, three or four-stage versions. With the GPX planetary gearheads, the Source: MaxonSource: Maxonpressure angle of the toothing has been optimized to achieve longer uptimes.

The matching ENX 4 MAG (magnetic) incremental encoder expands the ways the drive system can be used, for example in surgical robots. In this size class, the ENX 4 MAG encoder is a first on the market and uses the same magnetic principle as the slightly larger ENX 6 MAG and ENX 8 MAG versions.

The new drive systems from the ECX family can be configured online and ready for shipping in 11 working days

The EtherCAT version of the EPOS4 Micro 24/5 positioning controller is a new product. The controller's functionality, operation, software and accessories are derived almost directly from the existing products in the EPOS4 range. It is suitable for use with both brushed DC and brushless EC motors with a continuous power of up to 120 W and has comprehensive feedback options such as Hall sensors, as well as digital incremental and SSI absolute encoders. The motion controller with its compact design is the optimal solution for integration into single-axis and multi-axis systems, such as small devices or robotic systems.

In addition to the new Micro design, the EPOS4 Compact 24/5 EtherCAT three-axes will follow in the summer of 2020, as a compact plug-and-play three-axis positioning system. The three-axis positioning system is based on the EPOS4 Micro and demonstrates the small size and high functionality of these multi-axis solutions.
