What to consider when selecting brakes for servomotors

Whether in industrial robots, vertical axes in machine tools or in servo axes in medical engineering - moved loads must not drop or crash in an uncontrolled manner after power switch-off or in case of power failure or emergency stop. Safety brakes, which hold the axes in their position reliably and safely, ensure that this does not happen. Incorrect selection or dimensioning of these brakes can lead to serious injuries and/or damage to property. Therefore, it is essential that you take a critical look at the technical product details and the performance spectrum of the provider when selecting brakes for servomotors.

How tilt sensors ensure stability of platforms, lifts and cranes

elobau offers a large number of sensors and other electrical components. They monitor the working condition of machines when these are in operation, and work in situations or conditions where slopes and angles may be important or simply need to be measured. This also includes tilt sensors, which are used throughout the machine and vehicle industry. They monitor the position of platforms, forks of forklifts, etc. Tilt sensors also report any imbalances that activate an engine's stop, alarms or brakes.

Should I choose a collaborative or cooperative robot?

Robots are becoming increasingly easy to use, more economical and suitable for a higher number of industrial applications. As human operators and robots increasingly share a common space in the manufacturing environment, the choice between a collaborative or cooperative machine is naturally being given more consideration. Barry Weller, Product Manager at Mitsubishi Electric, looks at the key features of collaborative and cooperative robots and how to quickly identify the best system for an intended application.

Achieving functional safety within drives without using encoders

What is the goal of functional safety? To minimise the risks posed by technical equipment to humans and the environment. Machine tools, for example, can endanger operators and technicians with tools that rotate at high speeds. Drive technology that ensures the required safety functions without encoders offers the user various advantages, says Mark Checkley of KEB.
