Abstract

A novel motor controller (100) controls a stepping motor (1) and includes a command value calculator (101) to calculate and output a speed command value (Étgt) and an angle command value (¸tgt) based on a reference clock. A control method selector (111) is included to select one of the open-loop control and the closed-loop control in accordance with the speed command value (Étgt). A command value output unit (103, 104) is included to output a first target value as the first current command value (idt) when the open-loop control is selected and outputs a second target value as the second current command value (iqt) when the closed-loop control is selected. The motor controller (100) controls the stepping motor (1) based on the first target value (idt) when the open-loop control is selected and the second target value (iqt) when the closed-loop control is selected.
