A 1000kW DC motor is producing excessive magnetism on its platform and surrounding structure, causing bearing failures, and the source remains unidentified after standard testing.

Standard electrical testing (e.g., insulation resistance, winding resistance) fails to detect the root cause of stray magnetism and bearing current, leaving technicians without a clear diagnostic path.

uses bolt stuck to frame to detect magnetism
performs standard electrical testing that misses the issue

Implied Software Gaps

Real-time bearing current monitoring device with magnetic field mapping and diagnostic guidance

App Concept

BearingShield Diagnostics

BearingShield Diagnostics is a portable device that measures shaft voltage, bearing current, and stray magnetic fields in real time on large DC motors. It provides guided troubleshooting and alerts for earth brush faults or magnetization issues, preventing repeated bearing failures.

Key Features

Real-time shaft voltage and bearing current monitoring
Stray magnetic field mapping (Gauss meter integration)
Automated fault detection for earth brush and grounding issues
Step-by-step diagnosis guide for motor magnetism problems

Target Users: Maintenance technicians and electrical engineers in manufacturing facilities operating large DC motors (500kW+)

Revenue Model: $199/month subscription for hardware rental and analysis software, or $2,500 one-time purchase plus $50/month software access
