Xpert Intelligent Equipment Co., Ltd. is one of the leading manufacturers and suppliers of bldc-s4215 motor in China. We have world-leading production equipment and strong manufacturing capabilities. Welcome to wholesale bulk cheap bldc-s4215 motor in stock here from our factory. Customized orders are welcome.
Positioning of 4215 motor
The motor specializes in 12-15 inch heavy-duty long-range FPV drones, serving as the flagship model in the entire series with the strongest load capacity, highest power, and most comprehensive operational capabilities. It balances ultra-high thrust, ultra-long range, and ultra-long operational duration.
Supports customization
Standard 650KV, customizable to 400/500/800KV; the low KV side emphasizes heavy-load hovering and long-duration tasks, while the high KV focuses on high-speed long-range flights and rapid inspection missions, capable of covering all professional-grade scenarios.
Standard hole position
25×30mm heavy-duty dedicated mounting hole spacing, compatible with mainstream 12/15-inch X8/X6 heavy-duty long-range frames, allows direct upgrade replacement for 3115/3212; supports 6S-8S wide voltage input, matches 100-120A high-power brushless ESCs, requiring no frame or flight controller modifications for simple and efficient upgrades.
Thrust without attenuation
15mm thickened iron core with higher magnetic flux density, enabling prolonged hovering without power loss and thrust attenuation. Under the same battery capacity, heavy-load endurance is increased by 18%+ compared to same-class high-thrust motors. Equipped with N55H ultra-high-strength, high-temperature-resistant neodymium magnets and Class C 220°C ultra-high-temperature insulated enameled wire, it supports long-term full-power operation without demagnetization or burnout, adapting to all-weather industrial environments.
