Title: Permanent magnet rotor type synchronous motor
Inventor: FUJIWARA TOSHIAKI
IPC: H02P1/46
Filed: 1983-07-21
Abstract: PURPOSE:To enable to readily control the rotating direction at the starting time by controlling so that the magnetic force applied to a rotor becomes the prescribed direction from a magnetic relationship between the rotor and a stator during the prescribed time after a power source is turned ON. CONSTITUTION:When a power source is turned ON, time measuring means 13 does not output information to normal operation control means 14 until a predetermined time T1 is elapsed after the power source is turned ON. Accordingly, logic sum information output means 15 transmits information of initial operation control means 11 to power source current control means 16. The means 11 judges the steady state of a rotor 1 to a stator 3 on the basis of the information from magnetic field direction detecting means 10 to control stator poles 3a, 3b and the pole generated at an auxiliary stator 18, i.e., the direction of the current flowed to an armature winding 4 and an auxiliary winding 19. When the time T1 is elapsed, the means 14 output information preferential to the information of the means 11.
