At 10kW, Cooling Drives The Build, Not Catalog Specs.
Below 5kW a brushless motor is largely a catalog choice — pick a frame, pick a winding, ship. At 10kW the math changes. Continuous 10kW in a closed motor housing produces 1–1.5kW of waste heat that has to leave the iron faster than it accumulates. That single constraint determines whether the motor is a 130mm forced-air industrial unit, a 180mm liquid-jacketed marine drive or an oversized 200mm naturally-cooled mixer drive — and those are very different motors despite the same nameplate power. Our engineering team specifies cooling, winding and frame together based on your actual duty cycle, not just the rated number.
- Continuous duty (industrial pump, marine cruise): liquid cooling or oversized frame
- Intermittent duty (large EV peak traction): forced-air, smaller frame
- Short-cycle burst (heavy CNC spindle): 7kW continuous base with peak headroom
- Every project starts with a duty-cycle review before frame is locked
