摘要： Device for controlling electric motors of the asynchronous motor type operated by means of three-phase alternating current. For producing the operating current of the motor (5) a voltage-controlled oscillator (2) is foreseen and a generator (4, 6) controlled by the same and conditionally fed from a direct current source (1). The control device (3, 7, 8) is arranged to receive the pulse which arises upon operation of the motor (5) in its feed conductors (10-12) for alternating current and is thereby arranged to detect changes in the pulse shape of the operating voltage which occur due to electromotive forces induced from the motor windings when these are passed by the induced field of the rotor. These changes vary with the size of the slip. On the basis of the level of said deviations, a proportional voltage is induced which is transferred to the oscillator for its frequency control. With changes in the rotational torque loading on the motor, the control voltage is thereby changed and also the frequency of the oscillator and consequently the rotational speed of the motor, so that an adaptation to the operating resistance is obtained.

摘要： Control means for asynchronous electrical engines, driven by an alternating 3-phase current, which creates a rotating electrical field in the engine, which at a certain lag in rotation from synchronous rotation in the rotor induces a field, which creates the field necessary for rotation of the rotor. An oscillator (8) and a frequency controlled electrical bridge (1) for the alternating current combine to create the driving current for the engine (2). The control means is arranged to receive that pulse which during operation of the engine is created in its feeder circuits for alternating current, and is designed so as to detect changes in the pulse shape of the driving voltage, which are caused by electromotive forces induced by the engine windings when these are passed by the induced field of the rotor, where the size of the changes vary with the size of the lag. The bridge (1) is fed from a power regulator (6) which through changes in said electromotive forces is controlled to output to the bridge (1) a voltage which varies according to the size of the lag so that a variation in torque load on the engine (2) and an accompanying tendency to change in the lag is compensated in a control process.
