Abstract:
A system for testing electromagnetic characteristics of an electromagnetic steel sheet includes: a driving unit operable based on a non-sinusoidal wave control signal from a control unit and a floating voltage to output a control output; a power output unit operable based on the control output from the driving unit to output a voltage output at an output side coupled across a first winding wound around the electromagnetic steel sheet such that an exciting current flowing through the first winding is generated in response to the voltage output, thereby resulting in an induced voltage across a second winding wound around the electromagnetic steel sheet; and a measuring unit outputting to the control unit an output corresponding to the exciting current and the induced voltage measured thereby such that the control unit obtains the electromagnetic characteristics of the electromagnetic steel sheet based on the output.
Abstract:
An electromagnetic winding assembly includes first and second housing halves and first and second conductive units provided on the first and second housing halves, respectively. The first and second housing halves are detachably connected to each other so as to define cooperatively a core-receiving space therebetween and to connect electrically the first conductive unit with the second conductive unit such that the first conductive unit cooperates with the second conductive unit to form at least one coil-like electrical conductor configured to be wound around a core received in the core-receiving space.
