Stepping motor driver |
摘要 |
A stepping motor driver comprises: an excitation angle generating means which generates an excitation angle from an external command pulse; a current control means which controls exciting currents for a stepping motor according to the excitation angle and a current command; a current detection means which detects phase currents of the stepping motor; an angle detection means which detects a rotor rotation angle of the stepping motor; a torque component current calculating means which calculates a torque component current from the phase currents and the rotor rotation angle; an absolute converting means which obtains the absolute value of the torque component current; and a current command output means which outputs the current command depending on the absolute value of the torque component current.
