End of Line (EOL) e-motor test system

Scope of testing

• Resistance measurement of winding resistances, temperature sensors, insulation resistance of the winding, contact resistance of the shield connections
• HV testing
• Determination of the resolver offset angle
• Residual magnetism at the shaft end of the rotor
• Idle values of the motor
• Determination of the nonlinearity of the resolver
• Electromagnetic force (EMF)
• Total Harmonic Distortion (THD)
• Speedripple of the motor speed
• Structure-borne noise measurement
• Determination of the friction losses
• Etc.
