Electric Motors for Drone

Abstract

　First, this article describes the features of motors used in drones. The discussion by the members of the investigating R&D committee on small motors and their control technology to satisfy service robots requirements has shown that the requirements for drone motors include "the durability and failure resistance" to avoid crashes, "the long-time drive", and "the weight reduction". Therefore, next, this article explains the methods for failure resistance, long-time drive, and weight reduction for the drone motors.
