Common Faults and Maintenance Tips for Brushless Hub Motors in Logistics Warehousing Environments

Common Faults & Preventive Maintenance for Brushless Hub Motors in Logistics Warehousing

In the fast-paced world of logistics and warehousing, uptime isn’t just a goal—it’s a business imperative. At Shenzhen Jinhaixin Holding Co., Ltd., we’ve seen firsthand how critical reliable performance is for 8-inch (200mm) brushless hub motors used in electric pallet jacks, AGVs, and warehouse carts. According to our internal data from over 12,000 units deployed globally, up to 42% of unplanned downtime in material handling equipment stems from avoidable motor issues like power loss, abnormal noise, or mechanical loosening—often due to poor maintenance practices.

Real-World Case: A Warehouse in Dubai Lost 72 Hours of Operation Due to Motor Failure

A major distribution center in Jebel Ali experienced repeated failures in their fleet of 150 electric push carts. After investigation, it was found that dust accumulation inside the motor housing caused overheating, leading to winding insulation breakdown. The root cause? No scheduled cleaning or sealing protocol. Once they implemented a monthly inspection routine using our recommended IP65-rated protective covers and lubrication schedule, failure rates dropped by 89% within three months.

This case highlights why proactive care matters more than reactive fixes. Here’s what you need to know:

• Power Loss? Check voltage stability first—especially if operating on older industrial grids. If voltage dips below 24V DC during peak hours, consider installing a capacitor buffer.
• Unusual Noise? Listen for grinding sounds—it usually means bearing wear. Replace bearings every 12–18 months under heavy use (average 8 hrs/day).
• Loose Mounting? Use torque wrenches! Over-tightening damages threads; under-tightening causes vibration fatigue. Ideal torque: 18–22 Nm for M6 bolts.
