Electrical Testing of
E-Motors
The qualification of the electrical performances of an E-Motor or its components, is a fundamental operation along each phase of an E-Motor design and assembly process
Marposs can provide adaptable solutions for the quality check starting from laboratory down to the entire assembly process, to help reaching the best performance. From electrical testing and partial discharge measurements in a lab environment, through in-line (IL) stator/rotor testing, down to the complete end-of-line (EoL) test, Marposs is the one-stop partner for system integrators and producers.
Quality control for stators, both in wound and hairpin versions, requires that various functional characteristics are checked along the entire production chain. Before impregnation, the winding resistances, winding inductances and parasitic capacitances are checked, together with the insulation conditions. After impregnation, the end-of-line test of the stator requires that the state of insulation is checked first, in order to control the impregnation process.
The functional control on the rotors is characterized in a different way depending on the type of electric motor adopted and therefore on the relative rotor configuration.
Marposs offers a complete range of solutions dedicated to the functional test of any type of rotor, for in-line and off-line applications or for laboratory analysis and characterization.
The end-of-line functional test represents the key operation for the quality control of the fully assembled electric motors. The methods of carrying out the functional check may differ depending on the intended use for the testing station, for analysis activities during the product development and process set-up phase, or for the entire quality control at the end of the assembly line.
Discover our complete range of solutions dedicated to the functional testing and the end-of-line testing of any type of electric motor, DC motors or AC motors, synchronous or asynchronous, for in-line and off-line applications or for laboratory analysis and characterization.
