Micro Motor FAQ Section
What maintenance do micro motors require?
Brushless micro motors typically require minimal maintenance, with sealed bearings lasting the motor's operational life. For brushed models, we recommend periodic inspection of brushes and commutator (every 500-1000 operating hours depending on load). Always follow the manufacturer's lubrication schedule if applicable, and keep motors free from excessive dust or moisture accumulation.
