Load Chokes from TRAMAG in Test Applications for Drives Technology

Our load chokes serve as a motor replacement for testing single-phase and multi-phase electrical drives components and are therefore ideal for use in test systems and test equipment for drives technology.

Wherever inductive loads are required in the test process and the costly acquisition of a complete drives and test system, consisting of motor and, if necessary, brake, can be dispensed with, our TRAMAG load chokes are used as motor substitute loads. They serve, among other things, for testing the electronic switching and control components installed upstream of the motor, the converter and inverter units.

Lower investment costs, the replication of the necessary motor inductance without a rotating and thus largely maintenance-free drive unit, make the use of load chokes in converter test benches economically interesting.

Precisely fitting solutions for every application.

Depending on the application, the load chokes are specially dimensioned to the required motor inductance or to the level of the mains voltage of the drives system to be tested. Our chokes must also be specially designed for the various frequencies and clock frequencies of the converters and inverters to be tested.

For the specific design of the load chokes, all relevant values in addition to the rated inductance Lrat and load data / types such as the rotating field frequency frat and the corresponding clock frequencies of the converter as well as the application or load duration must be known.

TRAMAG: We are the Enablers

On request, it is also possible to accommodate different inductances in one load choke, with several tappings, thus enabling more flexible use in the test field.

For years, customers all over the world have relied on our TRAMAG solutions expertise in transformers, chokes and filters for reliable use in the electrical and economic optimization of their test and inspection equipment in industrial drive technology.
