The paper analyses the coupling features between electromagnetic actuators and controlled structures. Firstly,it constructs the coupling models of controlled structures and actuators driven by the constant current power amplifiers (CCPA) and by the constant voltage ones ,respectively. It also points out that actuators with CCPA are perfect in reducing dimensions of coupling models. Secondly,the frequency response of electromagnetic actuators coupled with controlled structures are studied. Lastly,the test shows the existence of the coupling. The test results are in agreement with the calculation ones.

In this paper the author introduces a stepping motor actuating power source which improves the current-frequency (I-f) characteristic and torque-frequency (T-f) characteristic of the stepping motor from two aspects. First, it uses a constant current power amplifier to limit the current flowing through the winding of the stepping motor. Second, the magnetic energy stored in the winding through which the current flows will transfer to the winding through which the current will flows when conducting state changes .In this way ,the fall time and rise time of the current of the windings becomes shorter and the high frequency characteristic of the motor is improved .At the same time ,the power consumption is also decreased.
