Alternators developed for aviation engines meet the power needs of systems on the aircraft by converting mechanical energy into electrical energy. Depending on the type of alternator, there are two different outputs: fixed voltage output and variable voltage output. Alternators producing a fixed voltage output operate independently of changes in the shaft’s rotational speed with the help of a battery and an alternator control unit, while in alternators producing a variable voltage output, the change in voltage value is due to the shaft’s rotational speed.

Alternator test systems are used for development or post-production quality control purposes. These systems simulate the shaft’s rotational speed in a controlled manner, allowing you to obtain data such as RPM, torque, voltage, current, winding temperature, etc., which are necessary to analyze the alternator’s performance.

E2T develops turnkey solutions for your fixed and variable voltage output alternator development and quality control processes. Our systems are 100% compatible with your alternator control unit, regardless of the communication protocol. With our direct-drive and parallel-drive solutions, especially for post-production quality control processes, and the E2T Control Suite, which allows you to define unlimited test steps, we contribute to making your test operations shorter and your alternators safer.
