Individual solutions for customised ring motors
Ring motors are basically large diameter torque motors that are characterised by a very flat design. For decades, we have been developing and manufacturing ring motors that are precisely customised to our customers’ requirements. It is not without reason that we say ‘Your idea is our drive’. It goes without saying that we are one of the leading companies for ring motors when it comes to customised requirements for ring motors with large diameters. If certain dimensions can no longer be realised as a complete motor or if segmented production is necessary due to the design, we speak of segmented motors. Information on Fischer segment motors can be found on this page.
Design and technology of ring motors
As the name suggests, these motors consist of a complete ring with a rather large diameter. Like all torque motors, Fischer ring motors are high and precisely controllable direct drives that deliver an extremely high torque even at low speeds.
Despite the large internal diameters, we build these motors very flat and thus save space. In combination with high-precision bearing technology, Fischer ring motors impress with first-class concentricity and extremely quiet operation.
This speaks in favour of Fischer ring motors:
Customised development and production
Efficient production of engine parts
Large diameters can be produced economically
Extremely powerful direct drive
Ring motors can be supplied as installation kits or finished motors
Areas of application for Fischer ring motors
Fischer ring motors are used wherever a compact design with a large internal diameter is required. The motors have to combine high performance with absolutely precise control.
Typical areas of application are
- Medical technology: Dort überzeugen sie durch ihre leise Arbeitsweise und kompakte Form, etwa in bildgebenden Geräten oder OP-Robotern.
- Aerospace: Ring motors offer high power density at low weight – ideal for use in confined installation spaces.
- Scanner systems: For example ring motors are also used in baggage scanners, as we know them from airports.
- Automotive engineering: They are increasingly being used in electric drives, steering aids and pump systems.
- Drive technology for special machines: Thanks to their modular design, ring motors can be optimally customised to individual requirements.
- Conveyor technology and industrial plants: Ring motors are very strong and get hard-to-start machines like mills, crushers or turbine drives moving.
Fischer ring motors are robust and reliable in operation. They combine high torques with corresponding rotation speeds and extremely precise speed control.
A real life example: rolling bearings in a computer tomograph.
We manufacture ring motors as installation kits for the company Franke GmbH from Aalen. In this case, the final assembly of the motor is carried out by the customer. Franke manufactures the ring bearing itself and integrates the motor base supplied by Fischer Elektromotoren into its revolutionary rolling bearing technology.
Based on our high-precision manufactured kits, Franke GmbH produces a slewing ring with a ring motor that sets new standards as a direct drive and enables an exceptional balance between power and weight.
Unrivalled performance and quality from the co-operation of two specialists.
The Franke – Fischer Elektromotoren teamwork is characterised by the expertise and enormous innovative strength of both companies.
Franke presents an innovative rolling bearing with an impressive service life, low wear and extremely high running performance. Running performances of up to one billion rotations are possible without any problems.
Franke GmbH describes its new rolling bearing technology as a ‘fusion of innovation and technical excellence that redefines the standards in the rolling bearing industry’.For more information on this pioneering product, simply click on the Franke logo.
It provides us with pleasure and a certain pride that we are part of this outstanding rolling bearing technology.
