摘要： A system and method for controlling a speed of a permanent magnet AC motor (38) based on a delay angle of a triac-controlled AC voltage signal (66) from a triac (34). A simulated load (54) connected to the triac (34) enables a load current and creates the signal (66). A first detector (48) detects a zero-crossing point of the AC voltage signal, and a second detector (50) detects a subsequent turn-on instance of the triac (34). A speed command generator (52) measures an interval between the zero-crossing point and the subsequent turn-on instance, and converts the delay angle to a speed command for controlling the speed of the motor (38). The simulated load (54) may include resistors (70) having a resistance which causes the load current to be below a holding current rating of the triac (34), thereby causing the triac (34) to turn off after the interval has been measured.

摘要： A drive circuit for an electric motor having a wound stator and a permanent magnet rotor, includes a controllable bidirectional AC switch connected in series with a stator winding between two terminals for connecting to an AC power supply. First and second position sensors detect the position of magnetic poles of the rotor. A voltage regulating circuit is connected between the two terminals and the controllable bidirectional AC switch and configured to supply power to the first sensor during the positive cycle and to the second position sensor during the negative cycle of the AC power supply such that the controllable bidirectional AC switch is switched between a conductive state and a non-conductive state in a preset manner, thus enabling the stator to rotate the rotor in only one predetermined direction during start-up.

摘要： For controlling d-c motors which are supplied with an armature current obtained by phase gating, the bucking voltage induced in the motor is particularly well suited. This voltage is calculated indirectly by a measuring unit which calculates the instantaneous bucking voltage of the d-c machine as a function of the phase gating angle calculated in the preceding computing cycle, the measured current conduction angle, the measured magnitude of the line voltage, the mean armature current value and the armature circuit resistance specific to the machine and the armature circuit inductance specific to the machine.

摘要： An improved arrangement for controlling the speed and direction of rotation of a DC motor responds to a variable bipolar input signal. A bipolar threshold detector coupled to the motor is used for the selective triggering of a triac during the appropriate half wave polarity of an AC source. Triac failure is prevented by a protection circuit. The arrangement incorporates a speed servo and senses the voltage across the triac to detect the speed of the motor.

摘要： A safety control device for a speed control circuit of a commutator motor having an ignition circuit includes a circuit for detecting an armature current and defining whether the commutator motor is energized with a supply current or with a free wheel current, a maintaining circuit for discriminating if the detected result is a continuously energized condition or an intermittent condition, and a bistable circuit. The maintaining circuit smoothes the detected voltage of the energized motor and maintains the voltage over at least one cycle of the power source and functions temporarily in an equivalent manner of continuous energization of the motor when power source is applied to the motor. The bistable circuit nullifies the ignition circuit of the motor control when the motor is in an intermittent energization and switches the ignition circuit into an effective condition as the maintaining circuit comes to accumulate the voltage above the predetermined level while no speed designation is made to the speed control circuit of the motor.
