摘　　要：自控行为是直流电动机及广义直流电动机的基本特征。广义直流电动机是直流电动机的同类型电机,也是直流电动机的新发展。自控变频反映直流电动机的属性,广义直流电动机是对电机本体采取自控变频措施的电动机。依托数学推理阐明了同步电动机本无自控行为,以电机本体为主件与自控电气配件组成的机电一体化电机,对电枢电流的频率及相位实施自控,从而产生气隙磁场钳位,使广义直流电动机呈直流电动机的性能特征。The self-control behavior is the basic character of DC motor and generalized DC motor. The generalized DC motor is the new development of DC motor. The attribute of a DC motor may be reflected by self-controlled frequency. The measure of self-controlled frequency is also applied in the motor body of generalized DC motor. By mathematical deduction, it was explained that there was non-existence of the self-control behavior for synchronous motor in running. The motor system which is composed of motor body and self-controlled attachment is able to carry out self-control to the frequency and phases of the armature current, so that the performance of DC motor appears in generalized DC motor.
