PLATINUM 4130 series motors are high-performance brushless 14-pole outrunner electric motors with excellent electrical properties, sophisticated design and top-notch manufacturing. Hardened steel shafts and high-quality bearings ensure long service life, while the high-quality materials used for the stator and rotor also guarantee excellent performance parameters and high efficiency. They are low-speed motors with high torque, capable of handling large diameter propellers and high pitch without the need for a gearbox.
Engine designation system: xxYY SL-zzzz
xx - stator diameter in mm
YY - stator length in mm
SL - sensorless (SensorLess) engine
zzzz - number of revolutions per volt (rpm/V), "KV"
PLATINUM 4130SL-490KV
PLATINUM 4130SL-490KV is a brushless motor designed to power models with a flight weight of up to 6000 g, powered by a six-cell LiPo battery.
Motor mounting: PLATINUM 4130SL-490KV is designed for both front and rear mounting. For front mounting behind the motor face, use four M4 screws that extend into the motor face by a maximum of 5 mm. The mounting screw holes in the motor face are spaced at regular 90° intervals on a 30 mm diameter circle. The motor bulkhead should be made of 6-8 mm aircraft plywood. A rear mounting kit (mounting cross, propeller carrier for rear mounting) is supplied with the motor.
The motor kit includes: PLATINUM 4130SL-490KV brushless motor with cables with soldered 4 mm gold-plated connectors, rear mounting kit, instructions.
