Abstract

A simple electric motor¹ has a problem in that the current applied to the motor per se can rarely trigger its rotation. Usually such motors begin to rotate after the rotor is slightly turned by hand (i.e., manual starting). In a self-starting motor, the rotor starts to rotate spontaneously as soon as the current is applied. This paper describes the initial condition of the rotor required for self-starting.
