Direct current motor control method for an actuator positioning motor that positions an actuator along a predefined path, whereby final position is calculated from current cumulative rotation angle plus a calculated braking angle

摘要

Direct current motor control method for use with an actuator positioning motor that positions the actuator along a predefined path. According to the method: the cumulative rotation angle of the rotor is measured from a time point at which a supply voltage is applied to the motor; the motor angular velocity is calculated from current operating values and a corresponding braking angle is calculated for this velocity; the power supply is cut when the sum of the cumulative rotation angle and braking angle correspond to a predefined adjustment path. An independent claim is made for a control device for a direct current motor for controlling the position of an actuator or positioning drive.
