Product information

Brushless neodym motors MEGA are designed for direct drive (propellers, ducted fans) and for drive with gearbox. Motors MEGA AC are six-pole 3 phase AC motors, hardened steel shaft is supported in two ball bearings with permanent grease filling. Neodym magnets of dynamically balanced rotor are kevlar bandaged. Efficiency reaches up to 88%. Motor has good efficiency even at high currents thanks to vent holes. Hand made stator, lightweight rotor and design of MEGA AC motors allows permanent high rpm operation.

Motors are made in 4 lengths and are designed mostly for direct propeller drive (without gearbox). However, gearbox can be used and motor ase suitable also for ducted fan drives. Motor can be used for models from 0,8 to 5kg. Output shaft diameter of this product line is 5mm.
