MOTOR ASSEMBLY FOR DRIVING A PUMP OR ROTARY DEVICE WITH A LOW INDUCTANCE RESISTOR FOR A MATRIX CONVERTER

A resistor assembly for a motor drive circuit for an electric motor assembly can have a generally circular shape. The resistor assembly includes a resistor with input and output connectors and a pair of conductor elements extending from the input and output connectors. The pair of conductor elements extend adjacent each other along a curved serpentine path so the resistor has a generally circular outer perimeter and a generally circular inner perimeter. The curved serpentine path of the pair of conductor elements allows current to flow through the pair of conductor elements so that magnetic fields generated by the current flow through the pair of conductor elements cancel each other, thereby providing the resistor with low inductance.

The invention concerns a coaxial resistor (1) having a forward conductor (6) and a return conductor (7) for conducting the current to be measured in opposite directions and having a resistor element made of a resistance material, the resistor element being arranged in the forward conductor (6) or in the return conductor (7) so that the current flows through the resistor element. The invention provides that the cross-section of at least the internal return conductor (7) is rectangular to the direction of current flow, which simplifies the manufacture of the coaxial resistor (1). Errors caused by thermoelectric voltages, TC of the resistor element and inhomogeneous current distribution are eliminated due to the design.
