《电机与拖动》期末复习提纲（Motor and drag final review outline） Motor and drag final review outline Chapter I introduction (abbreviated) Chapter ii dc motor 1. Understand the structure and model of dc motor. 2. Remember the main relationship between dc generator and dc motors rated data: Generator Pe = UeIe Motor Pe = UeIe eta e Me = 9550Pe/eta e The main characteristics of the magnetic circuit composition of dc motor and the main characteristics of the single wave armature winding are generally mastered. 4. Master the various excitation modes of dc motor. 5. Generally grasp the distribution waveform of air-gap magnetic density under excitation magnetic potential. 6. Master the armature reaction of dc motor and its influence on the motor. Seven, key control dc motor armature winding should feel electromotive force E2 = Ce Ф n and electromagnetic torque M = CM Ф Is firmly grasp the Es, Is the direction of the relationship between M and Ф. Eight, electromagnetic power Ω Pdc = M = master EsIs and its physical meaning. Master the basic equation of dc generator. 10. Master the power flow of the dynamo generator. The basic equation and power flow chart of the motor of the dc motor are very important. 12. Focus on the inherent mechanical properties of his motor, including equations and characteristics. 13.
