Abstract

PURPOSE: To enable changing of the output characteristic through a detecting coil, by providing a detecting coil at the inphase or the opposite phase position corresponding with two-phase stator coil and hole element then combining their output voltage with the output voltage of Hole element.
CONSTITUTION: Detecting coil 14 is wound over a coil block C1 and located at the position where it is electrically in-phase, for example, with the stator coil 4, then the field of rotor magnet is detected to induce the voltage which is in-phase with the output voltage from the Hole element 6. Detecting coil 15 is similarly provided in the coil block C3 of stator coil 5. Then the difference between the induced voltage and the output voltage from the Hole elements 6, 7 is produced from the synthesizers 16, 17 and provided to the amplifiers 10, 11. Consequently the motor output characteristic corresponding with the load specification can be obtained by changing the field detecting sensibility of the detecting coils 14, 15.
