In 2025, a well-known industrial equipment supplier from Europe approached BG Motor with a specific need: a compact, high-speed AC motor solution for use in a portable oil pump system. The system required fast startup, consistent pressure output, and stable long-term operation. Traditional AC motors on the market were either too bulky, too slow, or incapable of sustained high-speed performance.
To meet the client's performance goals and space constraints, BG Motor was tasked with developing a custom-built 220V single-phase AC motor delivering up to 15,000 rpm under a 750W power rating.
During the early phase of development, the client faced multiple technical obstacles:
1.High-speed limitations: Conventional motors typically max out at 6000rpm–9000rpm. The required 13000rpm–15000rpm demanded optimized rotor design, precise balancing, and reinforced insulation systems.
2.Temperature rise control: Continuous high-speed operation in a compact oil pump design would generate considerable heat, risking motor efficiency and component safety.
3.Dimensional constraints: The pump body had strict installation dimensions, making a compact but powerful solution essential.
4.AC power supply requirement: The customer preferred a 220VAC motor to match on-site utility access and reduce system complexity (no external driver or transformer).
To address the above challenges, BG Motor’s R&D team designed and delivered a customized single-phase AC universal motor with the following features:
Technical Highlights:
Rated voltage: 220VAC, single phase
Rated power: 750W
High-speed output: 13000rpm–15000rpm
High-speed rotor balancing: Precision dynamic balancing<2.5g.mm for reduced vibration
Temperature control: Enhanced cooling channels and high-temperature class insulation system (Class F/B)
Brush system: Optimized brush holder structure with reinforced brush life ≥1000 hours under full speed load
Compact design: Customized housing to fit the client’s limited assembly space
Built-in overload protection: Motor thermal protector to ensure safety under continuous duty
This motor was directly integrated into the client’s oil pump system, enabling rapid oil extraction, fast startup time (<1s), and stable high-pressure output.
BG Motor provided full lifecycle support for this custom project:
Technical documentation, including performance curves, electrical diagrams, and installation drawings
Testing support with pre-delivery full-speed performance test reports and vibration analysis
Field adjustment guidance during client’s prototype installation
Warranty service: 12-month quality warranty with optional on-site technical inspection
Spare parts support: Brush kits, bearings, and thermal protectors available for long-term servicing
The client reported zero failure after 6 months of continuous field operation, and expressed intent to expand usage to other oil circulation equipment in their product line.
