发明名称 THE CONTROL DEVICES OF ELEVATOR
摘要 <p>The apparatus comprises the means to generate a correction signal having a predetermined frequency, phase, and magnitude which can cancel the magnetic flux ripple of the induction motor attributed to a shaft deflection. The correction signal is super-imposed on either of the components parallel and orthogonal to the secondary interlinking magnetic flux so as to control the primary current.</p>
