Engineers developing high-power propulsion systems for heavy-lift UAVs, eVTOL aircraft, or electric boats face a critical challenge: 20kW BLDC motor stator cores must deliver exceptional torque density, thermal management, and reliability under continuous high load. Substandard laminations cause excessive core losses, overheating, and premature failure. Reenives delivers precision-engineered 20kW BLDC stator cores with ultra-low loss silicon steel, advanced epoxy coating, and liquid cooling integration — enabling next-generation electric propulsion.

What is a 20kW BLDC Motor Stator Core?

A 20kW BLDC motor stator core is a large-diameter laminated electromagnetic core (typically 180-280mm outer diameter) that forms the stationary part of a 20 kilowatt brushless DC motor. These stators feature thick laminations (0.35mm) of high-saturation silicon steel, optimized slot geometries for high copper fill, and integrated cooling channels for thermal management. For 20kW class motors — powering heavy-lift drones (50-100kg payload), eVTOL aircraft, electric boats, and industrial machinery — stator core quality directly determines power density, efficiency, and continuous duty capability. Reenives manufactures these high-power stators using premium 35PN210 or M470-50A materials with precision interlocking and optional liquid cooling jacket integration.
