Driving Circuit Design and Simulation Modeling of DC Servo Motor in an Updated Game Controller

A kind of new circuit was designed to model DC servo motor in the simulation software LTspice based on machinery & electric principles of servo motor.In term of the model,the driving circuit of the DC servo motor in an updated game controller was analyzed and optimized.A series of analogue electronic circuits were designed to model the running of motor and relative electric and mechanic variable were simulated during the model runs.The result of simulation proved the model of DC motor which solved a bottle problem of modeling DC servo motor by equivalent circuits,and the simulation was applied in design of practical product,the game controller which performance becomes better as well as the cost becomes lower.
