SEPARATELY EXCITED PARAMETRIC MOTOR

摘要

PURPOSE:To provide a parametric motor being easy to control a rota-tion direction and rotational speed. CONSTITUTION:A separately excited parametric motor, in which magnetic fields generated at the time of applying AC to first and second windings 3 and 4 are applied to a stator arranged around a rotor 9 in the manner of perpendicularly intersecting to each other and the rotor 9 is rotated by a rotating magnetic field generated through the composition of these transverse magnetic fields and the phase of AC applied to the first and second windings is con-trolled so that the rotation direction and rotational speed of the rotor 9 are controlled too.
