PURPOSE: To obtain a motor controller for realizing high speed starting in which a stabilized learning value can be obtained even if the controller is subjected to disturbance during the learning. CONSTITUTION: Outputs from a position signal generator 2 and a frequency generator 4 engaged with a cylinder motor 1 are threshold processed, respectively, through comparators 3 and 5 to produce signals SPG and SFG which are taken into a control processor 20. The signal SPG is subjected to phase comparison with a reference signal SPR at a phase error signal generating section 7 whereas the signal SFG is fed to a speed counter 10 where the period is measured. They are subjected to filtering at a core section 21 and control the cylinder motor 1 through a drive circuit 17. |
