| Abstract: | The magnetic network model of hybrid step motor is established according to the air gap late permeance method, and the expression of the harmonic back EMF is deduced. A novel method that uses the harmonic back EMF signal to extract the rotor position is put forward, and a new position sensor merged into an organic whole with the motor is designed. On this base, the closed - loop control method of hybrid step motor using the harmonic back EMF is investigated, and the microcomputer control system of step motor is designed. The feasibility of of closed-loop control of hybrid step motor using the harmonic back EMF is proved by the comparative experiment between the open loop and the closed- loop. |
