CONTROLLER OF ATTRACTION TYPE MAGNETICALLY LEVITATING GUIDE MAGNET

摘要

PURPOSE:To obtain a guide force of self-recovery force or larger and enable to independently control the guide force and a levitating force by supplying a pulse having variable width to two electromagnets disposed in two starts. CONSTITUTION:A control pulse generator 30 alternately generates pulses of high and low levels in the prescribed period. The ratio of the time width of the high level pulse 2 and the low level pulse is varied in response to the guide force control signal from a calculator 36. A gate controller 31 controls a passage time to the rear stage circuit of the output pulse of the generator 30 in response to a levitating force control signal. A distributor 32 distributes the output pulse of the controller 31 to chopper circuits 33, 34 in accordance with the level. Electromagnets 5a, 5b are constructed in such a manner to be disposed in stars, the displacement and the acceleration are detected by sensors 35a, 35b, and inputted to a calculator 36.
