SAW MOTORS FROM FISCHER – RELIABLE PERFORMANCE, MADE TO MEASURE

Patented and consistently further developed. Fischer saw motors are convincing all along the line.

Many years of experience and a great deal of innovative strength – this is what characterizes Fischer saw motors.

We have been working with leading manufacturers of multi-blade saws, cut-to-size saws and other woodworking systems for many years and continue to build on our leading position with the highest quality and constant innovation.

Fischer 2025 saw motors – that’s new:

The labyrinth seal has been consistently further developed and improved. The compressed air requirement can be reduced by approx. 80 percent. Economical compressed air consumption combined with high efficiency noticeably reduces operating costs.

In addition, Fischer saw motors are even better protected against the ingress of dirt. With this innovative solution, the patent protection of our saw motors has once again been extended by 10 years.

The newly developed labyrinth seal is made of steel and can be easily replaced. Solid baffle plates also effectively protect the labyrinth from damage. The baffle plates and the labyrinth seal can be replaced and underline the sustainability concept of Fischer electric motors. Thanks to the direct drive, Fischer saw motors are low-wear and maintenance-free.

How Fischer saw motors work

Saw motors from Fischer are designed as disk motors and are therefore particularly narrow due to their design. A disc rotor electric motor can be individually adapted to the desired requirements by means of the DC link voltage and its winding data.

The operating point of the disk rotor is determined by the relationship between the number of windings, torque and speed.

The motors are mainly used in multi-blade sawing systems for the flooring and furniture industry.

Direct drives are mainly operated at their thermal performance limit and must therefore be permanently temperature-monitored.

Temperature sensors are installed in the motors to protect against thermal overload. The following temperature sensors are available:

  • PTC (PTC thermistor)
  • PT 1000 (optional)

The newly developed labyrinth seal.

Baffle plates protect the seal.

Fischer saw motors are suitable for:

  • Insulation materials
  • laminate
  • solid wood
  • compound
  • sandwich
  • Aluminium
  • plasterboard
  • Plastic panels

Fischer saw motors are versatile:

  • Laminate sawing
  • Panel dividing saws
  • Table-tilt saws
  • Portal milling
  • Profiling technology

Thanks to the patented and space-saving design, Fischer saw motors are ideal for applications where there is little space available for installing the drive technology due to the design. Fischer saw motors are a first-class solution, especially when the smallest possible center distance must be maintained.

On the left, the classic motor for driving the saw blade. On the right, the Fischer synchronous saw motor of the latest generation. Extremely flat and even more efficient and powerful thanks to the newly developed labyrinth seal.

Convincing advantages of Fischer saw motors at a glance:

Maintenance-free: Due to the direct drive technology, the motors are not subject to wear and are therefore maintenance-free.

High precision: Through the use of a hardened and ground saw blade holder, a very high precision is achieved with regard to the axial and radial runout.

Compact: The motors are designed as synchronous disc rotor motors and can therefore be made extremely compact.

Low noise output: Our motors do not require gearboxes in the powertrain, and we also use only extremely high-precision and high-quality mechanical components. In this way we achieve a surprisingly low noise level.

High energy efficiency: Our saw motors with permanent magnets achieve the highest energy efficiency with efficiencies of 92-95 %.

Infinitely adjustable: Sensorless operation: Fischer saw motors are operated without a rotary encoder or angular measuring system. The speed can be infinitely adjusted via the motor controller.

High power density: We use extremely strong neodymium magnets – this enables us to achieve an enormously high power density even with very compact motors.

Here you can find more information on the following areas:

Fischer saw motors can produce much more than just a rotary movement. SThey draw their special strength from the magnetically pretensioned system with strong neodymium magnets. A gearbox can be dispensed with.

The system is basically secured against the ingress of dirt with sealing air.

IMPORTANT: The cooling takes place at the rear and has to be adapted by the customer to the installation situation. We advise that cooling be ensured by means of intake air or an additional external fan. For information on cooling and the design possibilities available, please contact our R&D team.

If a conductor loop is moved in a magnetic field, a voltage is induced into the conductor loop. A current-conducting coil generates a temporally changeable electric field that interacts with the constant magnetic field of the rotor. The resulting force is used to generate the rotary motion. A disc rotor motor consists of two components: the stator with coils and the rotor with permanent magnets. A disc rotor motor consists of two components: the stator with coils and the rotor with permanent magnets.

The distance between the stator and rotor (air gap) is decisive for the magnitude of the torque. A stable bearing system guarantees a constant air gap and smooth running.

Customer-specific electric motors are almost the rule at Fischer Elektromotoren. The electrical connection options differ entirely depending on the later use and installation situation and are implemented individually.

  • Cables with plugs – variable cable lengths
  • Open-ended cables with wire end ferrules – variable cable lengths
  • Built-in socket on motor housing

A second cable output may be necessary depending on how complex the customer specifications are with regard to additional components (for example measuring systems, temperature sensors, etc.) Basically, the following applies: Fischer electric motors are equipped with precisely the connections that the customer requires.

The listed performance data are feasibility proposals, our direct drives are always customer-specific.

Modernste Messtechnik zur Qualitätssicherung.

Wir setzen modernste Messtechnik zur Vermessung aller Motoren ein. An unseren Prüfständen werden die Parametersätze für die Inbetriebnahme sowie die Spitzen – und die Nennwerte des Motors ermittelt. Dabei werden der thermische Motorschutz und die Wasserkühlung berücksichtigt. Alle mechanisch verbauten Komponenten werden mit neuester Messtechnik wie 3D- und Höhenmessmaschine gemessen. 

Dank der patentierten und raumsparenden Bauweise sind Fischer Sägemotoren hervorragend für Anwendungen geeignet, bei denen konstruktionsbedingt wenig Platz zum Einbau der Antriebstechnik vorhanden ist. Insbesondere dann, wenn ein möglichst geringer Achsabstand einzuhalten ist, sind Fischer Sägemotoren eine erstklassige Lösung.

Links der klassische Motor zum Antrieb des Sägeblatts. Rechts, der Fischer Synchron-Sägemotor der neuesten Generation. Extrem flach und dank der neuentwickelten Labyrinthdichtung noch effizienter und stärker.

Überzeugende Vorteile von Fischer Sägemotoren auf einen Blick:

Wartungsfrei: Durch die Direktantriebstechnik unterliegen die Motoren keinem Verschleiß und sind somit wartungsfrei.

Hochpräzise: Mittels Verwendung einer gehärteten und geschliffenen Sägeblattaufnahme wird im Hinblick auf den Plan- und Rundlauf eine sehr hohe Präzision erreicht.

Kompakt: Die Motoren sind als Synchronmotoren in Scheibenläufertechnik aufgebaut und können dadurch enorm kompakt gebaut werden.

Geringe Geräuschentwicklung: Unsere Motoren kommen ohne Getriebe im Antriebsstrang aus, zudem verwenden wir ausschließlich hochpräzise und hochwertige mechanische Komponenten. So erzielen wir ein überraschend geringes Geräuschniveau.

Hohe Energieeffizienz: Unsere Sägemotoren mit Permanentmagneten erreichen die höchste Energieeffizienz mit Wirkungsgraden von 92–95 %.

Stufenlos einstellbar: Fischer Sägemotoren werden ohne Drehgeber oder Winkelmesssystem betrieben. Die Drehzahl ist über den Motorregler stufenlos einstellbar.

Hohe Leistungsdichte: Wir verwenden extrem starke Neodymmagnete – dadurch können wir selbst bei sehr kompakt bauenden Motoren eine enorm hohe Leistungsdichte realisieren.
