Test System for Electro and Servo Motors

06 December 2011 - GOEPEL electronic continues to extend its range of functional test systems with the introduction of CARMEN, a test system specifically developed for the verification of mechanic characteristics of electro mechanical and servo motors.

The CARMEN’s modular architecture enables specific orientations due to changing units under test (UUTs). Hence, CARMEN can be well adjusted and extended, suiting perfectly for fast setup and reconstruction of test sections for various applications.

In the test run, the entire characteristic curve between idling and full rotary speed up to the block can be passed through to determine parameters such as efficiency, structure-borne noise, performance and power consumption. A considerable array of test methods, e.g. thermal, overload or starting behaviour, self-inhibition, ripple determination, characteristic curve and resistance reproduction are already integrated in the system. Optionally, CARMEN can be extended to include an acoustic test. Depending on customer requirements additional tests can be implemented.

The motor test system CARMEN was designed according to customer wishes referring to various DC motors. The effort in adjusting the system to different motor types can be minimised by a consistent mechanic interface. When retooling to new UUT types, the software supports users in setting and classifying the mechanic system. The software’s modular structure helps to significantly save time in programming according to implementing test requirements.

In addition to deterministic control methods and possible applications of dynamic loads, the modular and easily extendable software concept allows the decentralised and simple integration of additional resources. For example, motors can be tested due to the Hardware-in-the Loop (HIL) principle.
