An OEM manufacturer of smart cleaning devices found that their robot vacuums struggled when transitioning from hard floors to deep-pile carpets. The previous micro-motors lacked sufficient torque, causing the side brushes to stall when entangled in carpet fibers, triggering overload shutdowns. Additionally, continuous high-current operation caused the motor housing to overheat, compromising the structural stability of the plastic gearbox.
The engineering team implemented the RS-365 12V DC Motor, leveraging its 27.7mm radial dimension to solve power redundancy issues:
High Torque Density: At a rated 12V, the RS-365 delivers stall torque far exceeding the 130/280 series, ensuring the side brushes maintain stable rotation for deep cleaning on resistant carpets.
SECC Metal Housing: The 27.7mm x 32.6mm metal casing acts as a heat sink, significantly improving heat dissipation compared to plastic-encapsulated motors and keeping temperatures below 40°C during 90-minute cycles.
Durability Engineering: The internal carbon brush structure is optimized to withstand power surges from frequent start-stop cycles, extending the overall maintenance interval.
| Key Metrics | Before | After (RS-365) | Evidence |
|---|---|---|---|
| Stall Rate (Carpet) | 15% - 20% | < 0.5% | Simulated carpet load test |
| Full-load Temp Rise | 65°C (Triggered) | 38°C (Stable) | Thermal imaging data |
| Installation Fit | 24mm Bracket | 27.7mm Std Bracket | 12V RS-365 Spec Sheet |
Conclusion: Following the RS-365 upgrade, the brand's robot vacuum significantly improved its "all-terrain cleaning capability," reducing after-sales return rates by 12% and securing placement in major Western retail channels.
