Abstract

PURPOSE:To make it possible to detect the rotational angle, speed, position on numerical value control axis of the subject motor by a resolver by providing means for detecting the rotor rotational angle based on the output of the resolver coupled to the rotor shaft of the motor. CONSTITUTION:The waveform shaping apparatus 22 of rotor rotational angle detecting means 13 shapes the output of a resolver 5, and delay circuits 23 and 24 delay the outputs of the waveform shaping apparatus 22 by 1/3 and 2/3 period of the resolver exciting waveform. Pulse generators 25, 26 and 27 generate outputs at the time when the outputs of waveform shaping apparatus 22 and delay circuits 23 and 24 rise up, and sample holding circuit 28, 29 and 30 subject the excited waveform of the resolver 5 to sampling by the outputs of pulse generators 25, 26 and 27. Multipliers 31, 32 and 33 multiply a positional command a, a deviation signal of a positional signal b and a speed signal d and the outputs of sample holding circuits 28, 29 and 30, and the thus multiplied signals are applied to power amplifiers 34, 35 and 36 causing currents to flow to armature windings for three-phase components of the commutatorless motor 8.
