42ECF Flat Brushless Motor

42mm BLDC Slotted Flat Motor with Outer - for Drone Applications

Designed with drone applications min mind, the new 42mm flat brushless DC motor with outer rotor is designed to have an open architecture. This motor has special features on the stator and rotor for improved airflow management which enhances performances and efficiency. The new 42mm motor has a 14 pole magnetic circuit and an optimized lamination stack which helps it deliver torque up to 205 mNm and a speed constant of 700 rpm/v. With a weight of only 100 grams, this compact 42mm motor is able to provide a very optimum thrust to weight ratio. The standard version is sensorless and helps in reducing complex wiring and overall cost to the application. A sensored version is also available as a custom request.

The new 42mm BLDC motor is an ideal motion solution for drone applications used in Aerospace & Defense, especially for drones designed for surveillance and reconnaissance.
