摘要： A motor controlling system in which a stepping motor can be always stopped at a constant or predetermined position. During initialization an excitation phase is stored after the motor has been detected to have passed a particular position. During actual operation, after the motor has been detected to have passed that particular position, the excitation phase of the motor is monitored and compared with the stored excitation phase. The motor is stopped upon coincidence of the compared excitation phases.

摘要： A control system moves an inductively controlled multi-phase motor in a forward or reverse direction. The motion may be in steps or it may be a continuous rotation. Dynamic braking of the rotation in either direction, either in steps or continuous rotation, is achieved by activating one or more phases of the multi-phase motor that lag the selected phase. Detent is accomplished by deactivating the lagging phase or phases at a prescribed time so that the selected rotational phase will then be applied to stop the motor at the desired motor pole.The speed at which the motor is moving when the lagging phase or phases are selected is measured by a velocity correction circuit that causes more current to be sent through the motor coils associated with the lagging phase or phases when the velocity is high than when it is low.When the rotation of the motor is continuous and stopping is required, the dynamic braking circuitry continually compares the decaying voltage of a predetermined standard RC time constant circuit with the decaying voltage of a measuring RC time constant circuit that varies in accordance with the velocity of the motor. A comparator circuit compares the two voltages and, until they reach a minimal prescribed difference, causes a current to flow in the motor coils associated with the lagging phase or phases. When a limit is reached, two specified motor phases are selected, one being a lagging phase, the lagging phase being deactivated after a prescribed period of time has elapsed, so that the motor then detents at the prescribed motor pole.

摘要： A method for referencing a polyphase stepper motor by monitoring the current step response in at least one driven phase is presented. The coil current step response is compared to past step responses in order to determine when an increase in or maximum load is present. A combination of step to step variance, step response variance from mean current magnitude, and average current magnitude variance, as well as other measures can be combined to create an algorithm output. The output is compared to a pre-determined threshold and if the value is greater than the threshold, the motor is commanded to halt its position, which remains magnetically synchronous. This position is then used as a reference point to zero, or to home the motor.
