Hello world, how have my mechatronic maniacs been since my brief hiatus?

I’ve spent the past month working as a lobbyist for the engineering industry. I’ve always wanted to try my hand at greasing someone else’s wheels. Ho!

On to this week’s slew of questions, a special thank you to those who contributed.

Is it feasible to expect regenerative braking to have a larger role in industrial automation as it becomes more efficient? – Carrie, WI

With the advent of AC technology, I increasingly see regenerative braking becoming commonplace in the industrial automation marketplace.

Electrical power can be had by back-driving AC motors, which basically become generators thereby offering mechanical braking and regenerative electrical energy. 

What is the best way to monitor mechanical clutch disengagement? – Jeffrey, CA

The obvious way is with the result, movement/non-movement of the drive member. But there are many other ways of electronic monitoring, such as proximity sensors.

If the clutch/brake is electromechanical you can also monitor the transient effect in the current signal.

Why should I specify a mechanical clutch over a hydraulic or pneumatic clutch? – Ben, IA

A great advantage to using a mechanical clutch/brake over hydraulic or pneumatic is that all the ancillary fluid/air lines, seals, tanks etc. can be eliminated if the customer utilizes a mechanical-only device.

Quick and painless. Comment below with questions for next month or qualms about this month, I’m headed back to the wheel greasin’.
