Industry: Smart Cleaning Robot Manufacturer
Cooperation Time: Since March 2024
A European intelligent cleaning robot manufacturer was developing a new 24V battery-powered household robot for:
Deep carpet cleaning
Low-noise residential use
Compact and lightweight structure
3–5 years product lifecycle
The engineering team required a high-speed vacuum motor that could deliver strong suction while maintaining stability under a 24V platform.
1.High Current on 24V Platform
At 24V,higher power means higher current.
This created risks of:Copper overheating.PCB stress.Reduced battery runtime.Thermal accumulation inside compact housing.
The team needed high suction without excessive hea
2.Noise at High Speed:
Target speed: 55,000–90,000 RPM.
At this speed range:Aerodynamic noise increases.Rotor imbalance becomes critical.Bearing wear accelerates
The target noise requirement was < 65dB, suitable for residential environments.
3.Lifespan Under Continuous Duty:
Competitor motors showed:Bearing degradation after 1,000–2,000 hours.Speed instability over time.Reduced airflow due to internal wear.
The customer required:Up to 20,000 hours lifespan.Stable suction over long-term use.Minimal maintenance risk.
The robot structure allowed only:2.6'' motor diameter.Lightweight configuration.Simple mounting structure.
Any size increase would require full structural redesign.
We provided a customized 2.6'' brushless DC vacuum motor with:
Voltage: 24V
Power options: 80W / 100W / 150W / 300W
Speed range: 55,000–90,000 RPM
Lifespan: up to 20,000 hours
Noise: < 65dB
Compact and lightweight design
Easy installation interface
Through:
High copper fill factor design
Low-loss magnetic circuit
High-efficiency winding layout
Improved ventilation channel
We reduced copper loss and controlled temperature rise even at 300W on 24V.
Result:
Stable current performance
Controlled internal temperature
Improved battery efficiency
By applying:
High-precision rotor balancing
High-grade bearings
Optimized airflow path
We achieved:
Noise < 65dB
Stable high-speed rotation
Reduced vibration impact on sensors
This improved product rating in residential markets.
Using:
High-temperature resistant insulation
Long-life bearing system
Strict tolerance control
The motor achieved up to 20,000 hours lifespan under normal duty cycles.
This significantly reduced warranty risk and after-sales cost.
The 2.6'' structure allowed:
Direct fit into compact robotic housing
Reduced system weight
Faster assembly
No redesign of airflow chamber
Engineers shortened development time.
After mass production integration:
Suction performance increased by 25%
Noise reduced below 65dB
Thermal stability improved
Field failure rate significantly reduced
Customer received strong positive market feedback
The product successfully launched in the EU market.
