The innovation behind the patent

The MIG encoder—short for Magnetische ImpulsGeber—represents a breakthrough in industrial motion control. Originally developed by the German company Ströter and now exclusively produced and evolved by BEGE, the patented MIG technology was engineered to solve the most common failure point in automation: the vulnerability of the encoder to its environment.

Why the patented MIG is unique

While traditional encoders are treated as “external attachments,” the BEGE MIG encoder is treated as an integral component of the drive.

  • The “Sandwich” principle: The patent covers the unique method of mounting the pulse generator between the motor and gearbox flanges. This flange design protects the sensor from external physical impact and environmental contaminants.

  • Space-saving integration: Because it uses the internal space of the flange, the MIG adds a mere 7 to 15 mm to the motor’s length. This allows engineers to add feedback capabilities to machines where a traditional encoder simply wouldn’t fit.

  • Contactless magnetic measurement: Unlike optical encoders that rely on fragile glass discs, the magnetic rotary encoder uses a vulcanized magnetic ring and a contactless sensor. There is no mechanical friction, meaning the precision does not degrade over millions of rotations.

  • The Ströter heritage: Building on the foundation laid by Ströter, the MIG was engineered to be a “universal interface.” It transforms any standard motor into a “smart motor” by simply placing the encoder between the motor flange and the gearbox. By maintaining the rigorous standards established by Ströter, BEGE ensures that every MIG encoder is a piece of precision German-Dutch engineering.

“Traditional shaft-mounted encoders are inherently vulnerable because they rely on external couplings and bearings that eventually fatigue under mechanical stress or alignment shifts. By utilizing the flange-integrated design, BEGE MIG encoders eliminate these mechanical failure points entirely, creating a contactless measurement system protected within the drive’s own structural housing for unmatched operational longevity.”

Find your BEGE MIG encoder in 3 steps

1. Identify the motor type

Match the flange standard to your existing drive system. Choose IEC (European), NEMA (North American), or Hydraulic (SAE/Orbital) motor interfaces.

2. Define the environment

Assess the exposure to moisture, chemicals, or vibrations. Standard Aluminum for logistics, or 316L Stainless Steel for washdown.

3. Select the required precision

Determine the required pulses per revolution or position data. MIG Basic for low-cost solutions, Nova+ for high-resolution, or AST for absolute position.

Frequently Asked Questions about BEGE MIG encoders

Below are answers to the most common questions about comparing BEGE MIG encoders.

What is a BEGE MIG encoder and how does it differ from traditional encoders?

The BEGE MIG encoder (Magnetische ImpulsGeber) is a patented, flange-integrated magnetic rotary encoder that fits between the motor and gearbox flanges. Unlike traditional external shaft encoders that require external attachments, the MIG uses a flange construction that protects the sensor within the drive’s own structural housing.

How does the BEGE MIG design save space in industrial drive systems?

By utilizing the internal space of the motor/gearbox flange, the BEGE MIG encoder adds only 7 to 15 mm to the motor’s total length. This compact integration eliminates the need for shaft modifications or fan cover extensions, making it ideal for machines with limited installation space.

Which BEGE MIG encoder is best for high-pressure washdown environments?

The BEGE MIG Stainless Steel encoder is the optimal choice, as it features IP69K-rated environmental sealing and AISI 316L construction. This variant is specifically engineered to withstand the aggressive chemicals and high-temperature cleaning cycles common in food and pharmaceutical processing.

What is the primary difference between the BEGE MIG Basic and the MIG Nova+ encoder?

The BEGE MIG Basic is a cost-effective solution for standard speed control with 1–64 pulses per revolution. In contrast, the BEGE MIG Nova+ is designed for high-precision positioning, offering up to 2,048 pulses per revolution.

Does the BEGE MIG AST absolute encoder require a battery backup?

No, the BEGE MIG AST uses 4-18 bit magnetic absolute sensing to retain its exact angular position even after a power loss. This eliminates the need for battery maintenance and removes the requirement for a “homing” sequence upon restart.

Can BEGE MIG encoders be retrofitted to existing industrial motors?

Yes, the flange design allows the MIG to be installed on any standard IEC, NEMA, or Hydraulic motor without shaft machining. It serves as a universal interface that converts standard motors into “smart motors” by simply mounting the encoder between the motor and gearbox.

Why is magnetic sensing more reliable than optical sensing in heavy-duty applications?

While optical encoders rely on fragile glass discs, BEGE MIG encoders use a vulcanized magnetic ring and a contactless sensor. This magnetic technology is highly resistant to shocks and can tolerate radial vibrations and axial play that often cause mechanical failure in optical units.

Which signal standards are supported by the BEGE MIG encoder range?

The range supports multiple industrial standards, including HTL (Push-Pull) for high noise immunity and TTL (RS422) for high-speed data transmission over long distances. The MIG AST absolute version utilizes digital protocols like SSI or BiSS for reliable, interference-free position data.

What is the maximum resolution supported by MIG encoders?

The MIG Nova+ achieves sub-millimeter precision with resolutions up to 2,048 pulses per revolution. When using the RS422 (TTL) line driver, it can reliably transmit signals over distances of up to 100 meters.

How does the patented contactless measurement of the MIG encoder ensure long-term precision?

Originally developed by Ströter and evolved by BEGE, the MIG encoder utilizes a vulcanized magnetic ring and a contactless sensor that eliminates mechanical friction. Because there is no physical contact or wear between components, the measurement precision does not degrade over millions of rotations, solving the common failure points of traditional encoders that rely on external bearings.
