    • A process for regulating the speed of rotation of an alternating current electric motor between two extreme angular positions of the rotor is characterized in that, on commissioning, the theoretical member (N) of complete periods (T) of the alternating current (1) to be supplied to the motor to drive it over such an angular displacement is determined, this theoretical number (N) is stored, on the basis of the chronological position (X) of these periods (T) complete in their total theoretical number (N), a table of the variations in the power supply to the motor required to ensure a predetermined speed is drawn up, in service, the actual instantaneous number (N') of complete periods of the alternating current between one extreme position (EI) and the other extreme position (EF) is counted, on the basis of the chronological position (X) of the actual member (N"), the power supply to the motor is aligned on the value given in the table for the corresponding thereotical member. The invention is applicable to the electrical and electrotechnical industries.
    • 用于调节交流电动机在转子的两个极角位置之间的旋转速度的过程的特征在于,在调试时,交流(1)至(1)的完整周期(T)的理论成员(N) 根据其总理论数(N)中完成的这些周期(T)的时间位置(X),将该理论数(N)存储到电动机上以驱动它来进行这样的角位移, 在确保预定速度所需要的电动机电力供应变化的表中,在使用中制定一个极限位置(EI)与一个极限位置(EI)之间的交流电的完整周期的实际瞬时数量(N'), 其他极限位置(EF)根据实际构件(N“)的时间顺序位置(X)进行计数,对电机的电源对应于表中给出的对应的对位构件的值。 inventi 适用于电气和电工行业。
