Hobbywing HW30416000 - Platinum 4120SL 250kv 12S Brushless Outrunner Motor
Double dynamic balance to control motor vibrationThe rotor and the complete machine undergo dynamic balancing. The rotor dynamic balancing is completed first, then the operating conditions are simulated. A secondary dynamic balance test is performed on the motor to ensure smooth operation and eliminate any imbalance in the assembly.
High efficiency and strong performance
The efficiency is increased by more than 2.5% compared with competing motors of the same specifications.
Efficient heat dissipation keeps the motor cooler
The rotor adopts a self cooling structure to further improve the motor's heat dissipation performance. The continuous running time of the motor is extended by more than 30% compared with competing motors of the same specification. The running time under heavy load is longer
The locking design of the propeller mount has been patented
The innovative designed propeller mount locking system can effectively prevent the propeller from flying off due to the loose propeller mounting nut, ensuring safe flight.
Diamond-shaped anti-slip design of the propeller mounting seat
The propeller mount seat adopts a diamond-shaped anti-slip design, which effectively prevents the propeller from slipping and free spinning, making it safer and more reliable.
Outstanding product design and industry-leading material selection
It adopts top-tier brand JNEH1200 iron core, 200°C high-temperature resistant wire, and international top-tier brand bearings to meet the needs of users in different scenarios. N52SH strong magnetic arc-shaped magnet design provides powerful torque for the motor. The motor's three-phase wire outlet is equipped with a custom-made silicone rubber sheath, taking into account both aesthetic appearance and insulation. The rotor has multiple locking designs, copper pad, circlip and bushing set screw to prevent the motor rotor from loosening and further improve the reliability of the motor. Multi-purpose design, the optional rear shaft propeller mount can also be installed on the rear end of the motor to meet the multi-purpose needs of different machines. Standard titanium alloy nuts and bracket mounting screws help to reduce the overall weight. The motor adopts a modular and easy to disassemble design, which facilitates easy cleaning and maintenance.
