    摘要: A brushless, synchronous direct current motor is operated by supplying a direct current voltage as an input voltage for commutating the motor phase windings. The speed of the synchronous motor is modified or varied in two speed ranges. In the first speed range, a linear change of the input voltage is carried out up to a speed threshold value. In the second speed range with higher speeds than in the first speed range, a vector modification of the input voltage is carried out, for example for controlling the speed of a fan motor.

    摘要: A process is disclosed for controlling the switching-off process of the branches of a reluctance engine whose stator is provided with windings to which are transmitted current pulses calculated as a function of angular position and speed of rotation of the rotor according to a predetermined algorithm. The excited branch is switched off when a switching-off angle is reached after a zero crossing reference angle. Two ranges of operation called "chop" range and blocked voltage range must be differentiated. The switching-off angle for both ranges of operation of the reluctance engine is calculated according to the same algorithm and is set by a regulator. In the lower speed of rotation range, the "chop" range, a pulse width modulated voltage is applied to the conductive branch, and in the upper range, the blocked voltage range, a constant voltage is applied. In both ranges, the switching-off angle is calculated from engine parameters and actual operation values to maximize torque yield and to trigger the switching-off process by converting said values into a switching-off pulse that switches off the conductive branch.
