An electric motor (E-motor) test stand (also referred to as a bench) is a test stand for reproducible testing of electric motors. In addition to the mechanical design, an electric motor test stand consists of accompanying measurement devices, sensors, and application software. The bus systems used to control and monitor the test objects are ...
These electric machines target 13 kW/kg and over 93% efficiency, while NASA Glenn Research Center is developing a superconducting electric machine with a 16 kW/kg goal and above 98% efficiency: a 0.4-m-dia, 6,800 rpm, 1.4-megawatt wound-field synchronous motor using a self-cooled, high-temperature superconducting rotor winding.
A growler is an electrical device primarily used for testing a motor for shorted coils. A growler consists of a coil of wire wrapped around an iron core and connected to a source of alternating current. When placed on the armature or stator core of a motor the growler acts as the primary of a transformer and the armature coils act as the ...
Such components could be electromechanical, motors or tools. The intended use of the test stand is for compliance testing of predetermined desired values and fatigue testing. A sophisticated mechanical component test stand houses several integrated measurement and control (imc) components, such as sensors, data acquisition devices and actuators ...
Electric motor/generator dynamometers are a specialized type of adjustable-speed drive. The absorption/driver unit can be either an alternating current (AC) motor or a direct current (DC) motor. Either an AC motor or a DC motor can operate as a generator that is driven by the unit under test or a motor that drives the unit under test.

A test bench or testing workbench is an environment used to verify the correctness or soundness of a design or model.. The term has its roots [citation needed] in the testing of electronic devices, where an engineer would sit at a lab bench with tools for measurement and manipulation, such as oscilloscopes, multimeters, soldering irons, wire cutters, and so on, and manually verify the ...
