Services
Beginning with the definition of targets to the
development of single components or even complex automation systems to the
commissioning and After Sales service - we see ourselves as a full range
supplier. In addition we also offer partial performances or single
components on request.
|
| |
|
Ritter develops and produces custom-specific system and
concept solutions for machine and plant constructors who...
- have to deal with difficult environmental conditions as for example
dirt, extreme temperatures or aggressive substances and therefore need
hermetically sealed-off modules
- work with standard components but require individual solutions
- do not have the space to build their machines around the components
and thus want to or even have to integrate the control electronics into
the machine.

|
Drive Engineering
Every moving device needs the suitable drive
technology. We offer customised solutions for electronically
controlled drives.
|
| |
|
The following examples are part of our range:
- Inverter technology for three-phase asynchronous and synchronous
motors (also in connection with Heat-Pipe cooling for electrical control
cabinets with high protection class positioned next to the machine)
- Precision speed control with simple sensor gears
- Motor electronics for brushless drives with reduced efforts
- Customised drives with integrated control and communication
electronics (in one housing)
- High dynamic servo stepper motor drives with extreme fast movements
in the range of milliseconds for ultra precise positionings
- Design of drive engineering with high protection class (IP 67)
- Customised electronic drive modules like controller and inverter
modules
- Multiple axle drive systems like unlimited number of drives on an
upright shaft with individually specified motion sequences
- Torque controlled drives for screwing machines
- Cabling with customised plug systems for direct installation into
the machine
- Profi-Bus and CAN-Bus crosslinking

Electronics
Electronics Development
From the conceptual study to the production of devices, modules, components
and systems - we offer all from one source. Electronic circuits are strictly
developed according to given pattern:
- Development and simulation with e.g. Mathlab Simulink
- Design of circuit diagram and development of software concepts
- Selection of components
- CAD circuit board layout designed with Mentor Graphics
Expedition™PCB
- Prototyping and type testing
- Testing device department for serial production
- In-circuit and function test of circuits
- 22-hour endurance test.
Even the construction and design of electromechanical devices,
components and modules are effected with approved tools:
- Solid Works 3D CAD
- Medusa 2D CAD
- Rapid Prototyping
- Analysis regarding heat dissipation of power electronics
Serial Production
We are specialised in serial production of electronic modules,
components and systems in our in-house production facilities. All facilities
are equipped ESD-safe.

(High Mix Low Volume)
- Lifecycle management for components (Last-order/Last-time-buy)
- Worldwide material purchase, also directly from manufacturer, on
demand access to our own components database
- Placement also possible with provided material

Induction Technology
Electrically conductive materials like steel shafts,
rollers, pipes, wires or meltings can also be heated by induction, that
means without contact. Therefore Ritter has developed special devices for
smaller heat outputs of 1.5 kW to 20 kW. Especially moving parts can be
heated quickly and with small effort. Sumptuous wiring for a resistive
heating wire is superfluous.
|
| |
|
Control Technology
Many control task solutions with standard components are
insufficient. We offer the adequate devices including software and develop
controller. The expenses are assessable: The development work would be
already paid at a purchase quantity of 200 pieces p. a. or if the electronic
controller could be beneficially integrated.

|
Special Electronics
Wherever electronics from serial production cannot be
applied, we assist with our long-term experience. Our engineers develop in
cooperation with our customers exactly the very electronics solution fitting
to the application. Whether special drive controllers, measurement data
logging in complicated geometrical structures or wireless transmission of
machine parameters our special solutions contribute to a optimised
exploitation of our customers' machines.

Cable Assembly
- Automatic Cable Assembly
- Semi-automatic crimp machines for all current contact variants
- Automatic machining centre for sheathed cables
- Cable assembly of wire harnesses and hybrid cables
- Production of coils
- Production of thermal elements
- Networked testing systems for supervision of production
- Worldwide procurement logistics, customer supply also possible
- Transport and packing according to customer`s request

Plant Construction
A main business area of Ritter is the development of
concepts for electric installations and serial concepts for machine and
plant construction in our in-house production and development facilities.
|
| |
|
The hardware design includes:
- Creation of requirement specifications
- Project planning, design, dimensioning and component selection for
the electric equipment
- Block diagram and detailed circuit diagrams with RACOS-EL-N or Eplan
5.x CAD systems.

Electrical Control Cabinet Productionn
Besides the development of optimised solutions and
providing of electronic and electromechanical components Ritter also
supplies the machines and installations with electrical control cabinets
that fulfil the EMC requirements of power electronics combined with
sensitive measurement and control signals. In the course of this it makes no
difference whether the cabinets are equipped with our own components or with
other devices. Already at early stage we have solved problems regarding for
example cooling of electrical control cabinets with high protection classes
to defend the electronics from aggressive environmental conditions. Our
design engineers are available at any time to furnish machinery and plant
equipment with special designs of electrical control cabinets using RACOS-EL
and Eplan.

|
We produce:
- Standard electrical control cabinets as well as cabinets for control
and feedback systems
- Inverter cabinets
- Input power cabinets
- Electrical control cabinet wiring
