Development Test Bench for DC Motors

Characteristic curve test bench for torques from max. 1 Nm to max. 100 Nm and speeds up to 10,000 rpm

CARMEN - Characteristic Test Bench for DC Motors

As a test environment for development and validation applications, CARMEN is a flexible system that can be configured as a 1-, 2- or 3-track system.

The advantage here is that a wide range of different UUTs (e.g. with or without a gear unit) can be tested easily and without the need for conversion. Test sections with active load machines of different power classes, high torques up to 70 Nm and a robust mechanics can be integrated as well as test sections with high speeds, torques less than 0.5 Nm and filigree mechanics.

A freely programmable drive system, which can function as both a braking and drive unit in clockwise or counterclockwise rotation (4-quadrant operation) of the test object, is part of the standard system scope. The test system also includes a high-precision torque sensor and a fieldbus controller, which can, for example, provide CAN or LIN residual bus simulation and the electrical diagnostic interface for the DUT.

All mechanical, electrical and thermal properties, overload capacity and the technical data such as efficiency and power factor are determined.

Application of the test scenarios via the central, cross-system database

If the test sequences are optimally parameterised, suitable load scenarios are programmed, certain operating point and limit parameters are determined, then these are administered via a central database, assigned to the test object type and applied across systems.

Do you have any questions or would you like us to send you a quotation?

In addition to the above mentioned standard parameters we also offer you further configurations of an engine test bench. We would be pleased to submit a proposal tailored to your specific applications!
