Two-phase stepping motor gauge control system |
摘要 |
A method for controlling a two-phase stepping motor gauge for an instrument cluster includes the steps of: providing a two-phase motor for displaying information to a driver, determining a desired position of the two phase motor at a rate and in a manner consistent with an intended application; updating a waveform to the input of a first inverter coupled to one of the motor coils; integrating the waveform using a first and second inverter to energize one of the motor coils. Thus, the present invention allows the control of a conventional two-phase motor coil using only one control signal. Additionally, the present invention requires low actual current to maintain gauge position.
