Design of Experimental Apparatus for Asynchronous Motor Principle

Abstract

Current domestic and international for the experimental apparatus been associated asynchronous motor design generally used hand horseshoe magnet rotates to drive the rotor rotates, While it is possible to achieve, the apparatus is too simple, and the effect is not in great satisfaction. To further improve the experimental results, a new type of asynchronous motor experimental device is designed, whose working mechanism is a DC motor as a driving source, driven by a reduction gear mechanism to produce a rotating magnetic field, the control circuit can be achieved by utilizing the rotational speed and adjust direction. By apparatus of the stator, rotor apparatus, the related motor control and display device design can make the operation more stable, more easily observed. The experimental apparatus can enhance students' awareness and understanding of asynchronous motor, so that the original abstract theory becomes boring incomprehensible gusto, to stimulate students' desire for knowledge, strengthen students' practical knowledge and ability, with higher practical significance. The apparatus simple shaped, with simple and safe operation, is able to facilitate teaching, with better promote the use of value.
