FRABA GROUP CELEBRATES 100TH BIRTHDAY WITH STRONG FINANCIAL PERFORMANCE AND MARKET GROWTH

FRABA GROUP CELEBRATES 100TH BIRTHDAY WITH STRONG FINANCIAL PERFORMANCE AND MARKET GROWTH

christian_leeser_ceo

The international FRABA Group, which is about to mark the 100th anniversary of its founding, has enjoyed a year of significant growth in sales and profitability. In fiscal 2017 (ending December 31) turnover increased by 21.5% over the previous year, with total sales revenues of € 31.5 million. Growth has been driven by strong performance of the Group’s two product-oriented business units: POSITAL (industrial position/motion sensors) and VITECTOR(safety/security systems for large motorized doors). FRABA now has 220 employees, located at offices in Europe, Asia and the USA.

“Our success has been the result of hard work and careful planning” comments Christian Leeser, majority shareholder and CEO of the FRABA Group. “Innovative products, such as our high-resolution IXARC magnetic rotary encoders and the motor feedback Kit Encoders have been well received by the market”. Leeser continues: “Our future success will be supported by our Aachen-based R&D center, which is making significant progress in the development of innovative signal processing algorithms for of our magnetic encoder products and improved performance from our Wiegand wire energy harvesting technologies.”
While the VITECTOR business experienced significant growth, especially in North America, the largest area of advance was in the production of compact Wiegand devices for energy harvesting. In 2017, production of these ‘mini-power plants’ (which convert rotary motion into electrical energy through a magnetic process) more than doubled. FRABA, which is the exclusive producer of Wigand wire, makes use of this technology in its self-powered rotation counters for multi-turn encoders. It also supplies Wiegand modules, packaged as surface-mountable devices, to manufacturers of gas and water meters. Here, the energy harvesting capability is used to eliminate the need for external power or batteries. There are now more than 500,000 Wiegand devices in use worldwide.

WIEGAND WIRE ENERGY HARVESTING COMPONENTS

WIEGAND WIRE ENERGY HARVESTING COMPONENTS

posital_wiegand_sensoren_590

POSITAL’s Wiegand assemblies offer a compact and efficient way of harvesting power for electronic circuits in electromechanical devices, eliminating the need for backup batteries.

The operating principle of POSITAL’s Wiegand modules is simple. A “Wiegand wire” is a short length of specially prepared Vicalloy (vanadium-iron-cobalt) wire. When exposed to a changing external magnetic field (e.g. a nearby permanent magnet mounted on a rotating shaft) the Wiegand wire will initially retain its original magnetic polarity, and then abruptly ‘flip’ its polarity when the change to the external magnetic field reaches a certain threshold. This sudden change in the magnetic state of the core induces a current pulse in a copper coil wound around the Vicalloy core. This current pulse is very short-lived, but the energy harvested from the mechanical movement of the magnet can be captured and used to activate a low-power electronic circuit. An important feature of the Wiegand effect is that the amount of electric power generated with each reversal of the magnetic polarization is constant and completely independent of the rate of change of the external magnetic field, even if this happens very slowly. POSITAL Wiegand modules have been used to reliably power rotation counters in tens of millions of devices, including multi-turn rotary encoders, gas and water meters.

  • Production Since 1974 – Started by John R. Wiegand
  • Proven In Encoders & Water Meters Since > 10 Years
  • Used In Access Cards For > 30 Years
  • Power Supply For Future IoT Applications
  • High Energy Output of ~170 nJ
 “The process for making Wiegand wire from raw Vicalloy wire was invented by John Wiegand in the 1970’s” comments Christian Fell, Chief of Technology Development for POSITAL-FRABA. “It involves a complex set of steps, including cold-working the wire through a combination of stretching and twisting, then heat-treating the product to lock in the desired characteristics.” POSITAL acquired the original wire-conditioning machinery and intellectual property from the Wiegand estate in 2013. Fell continues: “This acquisition has meant that we have reliable supply of Wiegand wire. It also gave us an opportunity to refine the manufacturing process for improved product quality. Thanks to our research, we can now produce wires that reliably generate 190 nanojoules of energy at 7 volts with each polarity flip”.
Wiegand assemblies are a core component in POSITAL’s IXARC multiturn absolute rotary encoders, providing a maintenance-free method for powering the counter that records the number of complete rotations that the device experiences. POSITAL also offers Wigand assemblies to other manufacturers. These consist of a 15mm length of Wiegand wire surrounded by a copper coil, all contained in an SMD-mountable plastic structure. Wiegand wire production is carried out at locations in the U.S. and Europe, ensuring a stable, reliable supply chain. These assemblies can be used wherever low-cost, zero-maintenance, battery-free energy harvesting systems are needed to energize electronic counters and other low-power electronic devices.

Now with the Open Source One-Cable-Technology BiSS LINE

MULTITURN KIT ENCODERS WITH BISS LINE INTERFACE

kit_encoder_biss_line

Now with the Open Source One-Cable-Technology BiSS LINE

POSITAL’s new family of kit encoders provide the manufacturers of motors and other machinery with rugged, accurate and cost-efficient tools for building rotary position feedback into their products. The new kit encoders are based on POSITAL’s highly successful self-contained magnetic rotary encoders. Now however, the core components of these instruments are available as separate assemblies that can be readily integrated into other products.

  • Asynchronous RS485 Interface, 4-Wire Configuration
  • Open Standard: BiSS Line
  • Smart Multiturn – Wiegand Technology – No Battery, No Gear!
  • Compact Single PCB Design
  • Auto-Calibration – No Mechanical Adjustment
  • Insensitive to Dust and Moisture

Non-Proprietary Interfaces Reduce Costs, Increase Versatility

The electronic interface for these encoders is based on non-proprietary BiSS Line and BiSS-C communications standards . Unlike proprietary, vendor-specific interfaces, these open-source standards are be supported by many manufacturers of sensors and motion controllers, freeing users from a “locked-in” relationship with a single supplier. Standard 4-wire RS485 connections are supported, so that motor manufacturers who adopt POSITAL kit encoders can often make use of existing connectors and cables. IP core software is available for FPGAs widely used in motion controllers. This reduces the development effort required to make use of BiSS communications technologies.

The BiSS Line standards also support a single cable approach to motor connections, with power and control wires combined in a single cable. Point-to-point or multi-slave network configurations are supported, simplifying wiring layouts in complex machines.

High Performance with Low Maintenance

The POSITAL kit encoder components offer advantages for motor and rotating equipment control feedback. Compared to analog resolvers, they provide improved accuracy and multiturn measurement capabilities. Their output is digital, which avoids the need for A/D converters in the control system. Compared to optical disk encoders, POSITAL’s magnetic encoders are less costly, less vulnerable to contamination from oil or dust and more resistant to shock and vibration. Multiturn absolute position measuring capability is based on an electronic rotation counter powered by the company’s well-proven Wiegand-effect energy harvesting technology . This system is self-powered, so rotation counts are always accurate, even if rotations occur when there is no control system power available. With no need for backup batteries and no need for periodic backup battery checks and replacements, maintenance requirements are significantly reduced.

Efficient Installation

POSITAL magnetic kit encoders are easy to incorporate into normal manufacturing processes since they don’t require near-cleanroom assembly conditions. A built-in self-calibration capability can be used to compensate for small sensor-to-shaft alignment errors occurring during assembly. The electronic components, including Hall-effect sensors, a 32-bit microprocessor and the Wiegand-wire energy harvesting system, are packaged in a convenient 36 mm diameter, 24.2mm deep unit. For servomotors with magnetic brakes, a special magnetic shield can be installed to isolate the magnetic pickups from external magnetic fields.

The resolution of the new POSITAL kit encoders is 17 bit, with an accuracy of better than +0.1°. The operating temperature range is -40 to +105 °C.
