KAVAN PRO motors are high-performance brushless fourteen or multi-pole electric motors with a rotating casing ("outrunner") with excellent electrical properties, sophisticated construction and top-quality manufacturing. Shafts made of hardened steel and high-quality bearings ensure a long service life, quality materials used for the manufacture of the stator and rotor also guarantee excellent performance parameters with high efficiency. They are low-speed, high-torque engines that handle large-diameter propellers and climbs without the need for a gearbox.

CAVAN FOR 8055-190
KAVAN PRO 8055-190 is a 22-pole AC motor designed to drive models with a flight weight of up to 15 kg with power from a 10-12-cell LiPo battery. It is perfectly suited for models in which you would otherwise fit a 40 cc two-stroke petrol engine.
Motor mounting: KAVAN PRO 8055-190 is designed for rear mounting. Use four M4 steel screws for fixing; engine bulkhead should be 8-10mm aircraft grade plywood.
Controller: When choosing a controller, be especially careful that it is a type designed to work with multi-pole motors (common controllers designed for 2-14 pole motors may not work correctly).
Motor kit includes: KAVAN PRO 8055-190 AC motor with cables with soldered 6 mm gold-plated connectors, rear mounting kit with two mounting crosses (O71/75 and O87/90 mm). You can download the complete manual for the motor here: AC motors KAVAN PRO 5050+ - Instruction manual
Note: Alternative designation according to the dimensions of the stator 7025-190.
