PT500mini Machinery Fault Simulator

The P500Mini Rotor Dynamics Simulator is driven directly by an ABB small three-phase asynchronous motor through a coupling, coupled with a frequency converter to adjust the speed. The adjustable magnetic powder load adds testing load to the test bench. Bearings with different types of faults can be selected to verify the frequency characteristics of bearing defects at different speeds. Fault gear testing, impeller blade testing, rotor dynamic balance testing, start stop testing, and shaft friction testing can also be conducted separately or in combination with various defects in a safe and controllable environment. As an innovative experimental platform for studying the fault characteristics of rotating machinery, it fully meets the extensive needs of teaching simulation and scientific research users.

The test bench is mainly composed of a three-phase asynchronous motor, a frequency converter, dual support bearings, a dynamic balancing rotor disc, impeller blades, a shaft, a single pole transmission gear set, a magnetic powder load torque adjustment mechanism, a shock-absorbing foundation base, and an adjustable magnetic powder load brake assembly.
