With e-mobility on the rise, test stand technology for automotive drives is undergoing fundamental change. What remains unchanged, however, is that precision, reliability and process safety are indispensable in measurement technology. Mayr Power Transmission will present its portfolio of components for test stand technology at Automotive Testing Expo Europe 2026.

Based on the proven ROBA DS steel disk pack coupling, Mayr’s ROBA DS Type 9120 is a weight-optimized aluminum variant. Compared with the steel version, the outside diameter is reduced by up to 10mm; mass and mass moment of inertia are 40-60% of the steel version, depending on the design and size – with unchanged performance density.

In addition to couplings, Mayr Power Transmission will also present its portfolio of safety brakes for test stand applications. This includes the ROBA guidestop profiled rail brake and the ROBA linearstop piston rod brake, which secure vertical axes and linear movements. The ROBA-stop M series provides a robust motor brake for compact protection directly at the drive motor.

The ROBA brake-checker is a sensorless module that monitors safety brakes and simultaneously supplies them with power. In combination with the ROBA gateway module, the solution becomes network compatible: the brake data can be read via an ethernet connection and displayed on a dashboard. Anomalies in the test process can be detected early, maintenance becomes plannable and downtime can be minimized.
