摘要： A pulsating D.C. voltage is developed by a rectifier (86) and is filtered by a capacitor (100) to facilitate application of a relatively smooth, enhanced D.C. voltage to a motor (106). The charged voltage of capacitor (100) is applied across a series circuit which includes a rheostat (118), a resistor (126) and motor (106). When the CEMF of motor (106) drops as a result of a decrease in motor speed, a diac (122) is biased through the voltage appearing across rheostat (118) and resistor (126) to cause an SCR (116) to fire. When SCR (116) fires, the voltage of capacitor (100) supplies a boost of power to motor (106) to overcome the decrease in motor speed. A circuit (212) prevents an overspeed of motor (106) from occurring while braking circuits (264, 266 and 268) provide for a dynamic braking effect when the motor is a universal motor.

摘要： Proposed is a control circuit which can be used for the phase control of an electric motor running off an a.c. power supply. The ground terminal of the circuit is connected directly, together with the cathode of a semiconductor switch (triac), with the load circuit. Thus voltage-cut-off means are unnecessary if signals from the load circuit are fed directly to the control circuit. In order to ensure the correct functioning of the phase synchronization input, an auxiliary power supply is connected in between this input and the ground terminal.

摘要： In order to determine the load moment of an electric motor on the basis of the drop in the speed of rotation under load, the drop in the speed of rotation in relation to a set speed of rotation is determined by electronic evaluation means during a momentary load. The corresponding load moment for a predetermined type of motor is determined by means of a reference table stored in a memory or by means of an algorithm. The load moment for different types of motors may be corrected by means of a correction factor. In addition, a temperature sensor is provided to correct temperature-dependent torques of the motor.

摘要： A circuit for the speed regulation of an electric motor with a field winding and an armature winding (1, 4) connected in series comprises a rectifier (5) in series with the motor and which is controlled by a phase shift control (30) as a function of a control signal dropping at the armature winding (1) and controlled through an operational amplifier (12). In order to obtain a high speed constance and a high control rate with simple means, the connections of the armature winding (1) are respectively connected to an input (10, 11) of a differential amplifier (12) of which the output (15) is connected to the input (19) of a comparator. To a second input of the comparator a rated value signal is affected, which signal is modified as a function of the current circulating through the armature (1).
