STM32 ARM-based 6-channel vibration verification platform that simultaneously collects vibration velocity (mm/s) data from different motor zones to objectively prove correct motor operation — combining live monitoring, adjustable alarm limits and detailed result reporting in a single interface.
Imbalance, misalignment, looseness and bearing problems in motors first reveal themselves as rising vibration velocity (mm/s) values. The Motor Test Bench was developed by Planck R&D to measure these values under controlled conditions, objectively verify whether a motor runs correctly, and base the pre-field pass/fail acceptance decision after production, maintenance or overhaul on data.
The system uses a two-layer architecture: an STM32 ARM-based embedded measurement layer reads 6 vibration velocity sensors placed on the motor and streams data to a desktop operator interface over 115200-baud serial communication. The operator manages the test via COM port selection, sampling rate configuration and the START TEST flow, monitors live mm/s, Peak and RMS values per sensor on separate cards, and freely adjusts alarm limits per test scenario. All events are recorded in an event log, and results can be exported to Excel.
High-precision 12-bit ADC reading of vibration velocity data from different motor zones.
All sensors tracked over time on the Live Vibration Velocity chart with overlaid Warning / Critical threshold lines.
Traceable pass/fail verification with peak, RMS, average, maximum and anomaly values.
