Making a Simple Self-Starting Electric Motor
Hong, Seok-In; Choi, Jung-In; Hong, Seok-Cheol
Physics Teacher, v47 n4 p204-205 Apr 2009
A simple electric motor 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.
