Kavan Electric motor Brushless Motor PRO 4345-730

KAVAN PRO series motors are powerful 14-pole brushless external rotors. The state-of-the-art design, hardened steel shafts, high-quality ball bearings, and premium materials for stators and rotors ensure long life, unbeatable performance, and high efficiency. KAVAN PRO series motors are comparatively low speed, high torque electric motors capable of using large diameter propellers without the need for a gearbox.

Motor designation system:
PRO xxYY-zzzz
PRO - Brushless external rotor electric motor
xx - Motor diameter in mm
YY - Motor length in mm
zzzz - Revolutions per minute per volt (RPM/V), "KV"

KAVAN PRO 4345-730 is a motor for model aircraft up to 3000 g total weight, powered by a 3-4S LiPo flight battery. It is ideally suited for EPO Warbirds, SIG Smith Miniplane, and other scale and aerobatic models.

Motor installation:
KAVAN 4345-730 is designed for both front and radial mounting. For front mounting, use four M3 screws that must not go deeper than 3-4 mm into the front casing. For radial mounting, use four M3 screws to fix the mounting cross to the motor bulkhead, which should be made of 5.0-6.0 mm plywood. The radial mounting kit is supplied with the motor.

Contents of the motor set:
KAVAN PRO 4345-730 motor with cable (gold-plated 4 mm connectors) and radial mounting kit.

Note: Alternative designation due to stator dimension: 3520-730.
