Research on Magnetic Momentum of AC Motor Armature Winding Based on Analytical Method

Armature winding magnetic motive force of AC machine is an essential part of Electric Machinery. The magnetic motive force of the armature winding of an AC motor is related to time and space. This concept is more abstract, which makes it difficult for students to understand. This paper analyzes the magnetic motive force of AC motor armature produced by some special conditions, such as star connection of AC motor stator winding lack-phase, power supply and winding disconnection of delta connection stator winding and AC motor dynamic braking. This method helps to promote students to better understand the magnetic motive force of AC motors, and can improve students’ ability to analyze and solve problems. Practice shows that the teaching research can obtain good teaching effects.
