Smart Combination: Bevel Gear Motor with SC8 Servo Controller

Annett Graupner — Thu, 01 Oct 2026 06:59:05 +0000

In hygiene-sensitive production environments (such as food and pharmaceutical processing), simply using a hygienic motor is not enough. The overall system is crucial—the motor, gearbox, and servo controller must function as a single unit, not as a compromise made up of individual components. The esitron SC8 servo controller, together with the stainless steel motor in hygienic design…

Servo Drive: Precise Motion for Modern Machines

Annett Graupner — Mon, 14 Sep 2026 09:16:09 +0000

In modern production and special-purpose machinery, motion has to be fast, precise and reliable. Axes accelerate, position, synchronize and brake – often in short cycles and under changing loads. This is exactly where servo drives come into play. They combine a precise servo motor with an electronic servo controller and a feedback system. This allows the drive to monitor its motion…

Fun with Drives! No. 12: Why do some engines that are in good working order sometimes fail the high-voltage test?

Annett Graupner — Tue, 08 Sep 2026 06:57:56 +0000

Episode 12 of “Fun with Drives” focuses on testing electric motors and what to pay special attention to during a high-voltage AC test. When performing an insulation resistance test, the first thing you need to define—in addition to the test voltage—is the leakage current. This current determines whether a motor is “alive” or “dead.” If these leakage currents occur, the systems “beep.”…

Fun with Drives! No. 11: IP Protection Ratings in Drive Technology

Annett Graupner — Thu, 23 Jul 2026 07:36:29 +0000

Motors, gearboxes, controllers—all drive system components are characterized by their protection class—an IP (Ingress Protection) rating. That’s what this installment of Fun with Drives is all about. IP54 Protection against dust and splashing water Typically used in machine shops IP65 Dust-tight Protection against water jets Anywhere where water is occasionally used for cleaning…

Practical Example: Synchronized Automatic Winding and Cutting

Annett Graupner — Mon, 13 Jul 2026 07:20:44 +0000

In systems that wind and cut film or packaging material, product quality depends directly on the precision of the drive control. Decentralized servomotors with integrated electronics, such as the esiMot series from esitron, enable precise speed control and tight synchronization between the winding and cutting units—something that can sometimes be a problem with traditional…

Is the control cabinet too full?

Annett Graupner — Wed, 08 Jul 2026 07:25:14 +0000

Anyone who designs a multi-axis special-purpose machine is familiar with the problem: The more axes there are, the more crowded the control cabinet becomes—not because of the controllers themselves, but because of the wiring. Decentralized servomotors with integrated electronics, such as the esiMot series from esitron, move the power electronics directly to the motor…

Fun with Drives! No. 10: Long Wires -> Dead Engine? Why?

Annett Graupner — Thu, 02 Jul 2026 08:47:43 +0000

In Episode 10 of the FunWithDrives videocast, Andreas Vonderschmidt discusses the topic of long cables. That’s because, once the cable length exceeds 10 meters, certain phenomena occur that are quite significant. And here, he’s referring less to phenomena like the brakes failing to release because there’s too much voltage drop across the cable—which is also a problem, but one that most people are…

From the production floor at esitron

Annett Graupner — Thu, 11 Jun 2026 06:47:03 +0000

Why? Because you can do some really cool things with it, and it truly combines a wide variety of engineering disciplines. It’s challenging, but also exciting. Take the product I’m holding in my hand, for example. It’s a decentralized servo-gear actuator—a combination of mechanical engineering, electrical engineering, and control engineering. The main advantage of this product is that it…

Fun with Drives! No. 9: Offset Angle in Encoder Systems

Annett Graupner — Wed, 20 May 2026 07:31:55 +0000

Setting the offset angle correctly in encoder systems is important to ensure that motors can run with controllers. In the video, I explain what you need to keep in mind. In a nutshell: ✅ The offset angle must be set in the encoder; otherwise, the motor will not run smoothly or may not run at all. ✅ Auto-tuning makes it easy to get a motor running, but it is not necessarily the optimal…

Machine Concepts Without Control Cabinets for the Hygiene Sector – Compact Drives in Hygienic Design

Annett Graupner — Tue, 05 May 2026 07:35:44 +0000

Until now, the only practical solution for this combination of requirements was to use a control cabinet controller and a corresponding control cabinet, or alternatively to position the drive units next to the machine or conveyor belt behind a protective enclosure. In other words, today you either install the compact drive outside the hygienic area or mount the controller in the control…
