Servomotors That Are Also Sensors

Indramat used to make some truly great products. The phrase “used to” is key. Indramat revolutionized industrial motion control with its servo drives, servo motors, and controllers back in the 1950s, but that company no longer exists today. In 1965, Indramat was acquired by Rexroth, and in 2001 Rexroth became Bosch Rexroth, and the only trace of the Indramat name remains on the countless servos that are still in use across the globe.

In a loose sense, Indramat became Bosch Rexroth, or rather a part of that company. And although Indramat no longer exists, the company that absorbed Indramat half a century ago is still making revolutionary contributions to industry.

Recently, Bosch Rexroth introduced servomotors that can act as sensors. Servos are, of course, extremely important in motion control systems, but until now they’ve had to rely on sensors to report information. These new servomotors, however, can act as their own sensor and provide temperature and saturation data to the servo controllers.

A servo that acts as a sensor benefits from improved performance such as better torque precision and tighter operating tolerance ranges.

This technology is even more important considering the fact that Industry 4.0 capitalizes on data and communication between machines as well as operators.

It’s no surprise that a company with ties to the Indramat name is revolutionizing industry through servos. That’s how Indramat got its start nearly 60 years ago, after all.

Maybe you’ve updated your motion control system in recent years, and you’re operating with Bosch Rexroth products. However, Indramat products can run for ages, and many plants are still using Indramat servos today.

Those old servo motors can’t act as their own sensors, but they can still get the job done. That is, as long as you take proper care of them. Contact us today for any of your Indramat repair, replacement, or service needs!
