Servo Motor or Induction Motor?

When an athlete needs to give 110% for the final drive for a touchdown or the jump to get the winning slam-dunk, they turn up the power and succeed when people didn’t think it was possible. Induction motors, however, can’t do this because of the way they’re built. In fact, most induction motors, also known… Read more »

Is Manufacturing As We Know It Dead?

3D printing is an intriguing idea and it’s clear it can be a big force for change in the manufacturing industry. In terms of what we do with Rexroth servo drives and servo motors, we’re not expecting that it’s going to make big changes for existing companies in the next few years. The technology is… Read more »

Why Do We Call It a Servomotor?

  You may call it a servo motor, servo-motor, servomotor, or just a servo. Indramat called their 20th century original an “AC Servo.” Why? Servo or cerveau? While it has been suggested that the French cerveau (brain) might be the root for this term, it’s more likely to be the Latin servus, which gives us… Read more »

Servo Motor Sizing

Have you ever tried to replace a button? You have to have the right size. A too-small button just can’t hold your clothes together when the buttonhole is meant for a much larger button, and a too-large button won’t go through the buttonhole. You’ve got to have the right size. The same goes for Rexroth… Read more »

Rexroth Motors and Washdown

Rexroth Servo motors are used successfully in a variety of different industries. They perform their job amazingly well with little or no maintenance for years. Then, there are washdown environments… No washdown rated motors Rexroth doesn’t actually make a washdown rated servo motor. They do make a couple of special option code motors with Steelite… Read more »

Noise Pollution

“Noise pollution” sounds like a metaphor, but the EPA recognizes it as an actual form of pollution. It can be serious, too — excessive noise for long periods of time has been shown to cause not only the predictable hearing problems, but also stress related conditions like heart disease and ulcers. Noise pollution has even… Read more »

MKE Servomotors and Explosive Environments

Watching an explosion in a movie is something we all enjoy—explosions are exciting, attention grabbing, and make action movies fun. But you don’t exactly want an unplanned explosion going off at work. MKE servomotors are made to prevent disaster in explosive environments and are the best Rexroth servomotor for jobs that could potentially turn into… Read more »

It All Started with a Hammer

When you look at your Rexroth drives and controls today, you probably don’t think of them as natural outgrowths of hand-forged iron hammers. Yet that was the beginning of the whole thing, back in 1795 when the Rexroth family’s iron foundry made fine iron hammers. A century later, they were using special casting methods that… Read more »

Understanding Model Numbers for Rexroth and Indramat Servos

When you’re staring at a metal model name plate on an old Indramat servomotor and take a look at our list of motors we service, you might discover that your legacy model isn’t listed. This doesn’t mean, however, that we don’t service your model of Indramat servomotor. Just like the company name, the model numbers… Read more »

Incremental Encoders need loving care

Incremental encoders in Rexroth or Indramat equipment come in a variety of shapes and sizes but they all share one trait: a piece of glass is where the encoding, or directions for the machine, are written. The benefits of these pieces of glass are that highly accurate encoding can be applied and they won’t wear… Read more »
