Specification

Features

• 320KV/380KV/740KV brushless drone motors are engineered for long-duration flights on multi-rotor drones, delivering ample torque at low RPM while maintaining peak efficiency throughout the flight.
• Patented Stepped and Knurled design keeps motors secure and ensures stable power output.
• To optimize strength and reduce weight, the V motor caps are extensively hollowed, maximizing the thrust-to-weight ratio and extending flight time.
• Each brushless drone motor undergoes rigorous dynamic balancing. Axial and radial runouts are strictly tested to design specifications, with performance variations controlled within 3%, guaranteeing precise and stable power for professional use.

Q: Is it necessary to lubricate a brushless motor?

A: No, it is generally not necessary or recommended to lubricate most sealed brushless motor bearings, as they are pre-greased from the factory and attempts to apply light oil can dilute the grease, attract dirt, and potentially worsen performance or damage the bearings. If lubrication is absolutely necessary, the bearings must be properly cleaned, and the existing grease replaced with a compatible, high-quality bearing grease, which is a complex process often not worth the effort compared to simply replacing the bearings.
