A series of test stations were designed and manufactured for comparative batch testing of households’ electrical motors. The test results interpretation will help the motor manufacturer to verify the manufacturing line reliability and keep constant quality parameters during manufacturing processes.
The first station purpose is to run the initial and final test cycles on a motor as free run test, actuated run (generator mode) magnet test and blocked shaft test. During test cycle rotation speed, noise level and multi-axial acceleration values are monitored. In addition, motor consumption and generated DC voltage are simultaneously recorded.
The second station will perform a destructive test on a batch of five motors by vibrating the motor shaft when the motor is running at nominal rotation speed. During test rotation speeds, housing temperatures are monitored.
The third station is for testing a batch of five motors under load where the force applied to the motor shaft is simulated by an inertial electromagnetic brake. The heat generated by the motors is constantly monitored and recorded on motor housing and rotor coil.
The instrumentation and interfaces in every test station are controlled by an industrial grade computer running licensed Windows 10 operating system and NI LabView software. On all stations the user can interact with the machines trough a graphical user interface having access to all functional parameters and digital readouts
