摘要： A synchronous motor controller is provided which is designed to diagnose whether a failure is occurring or not in energizing one of phase windings of a synchronous motor which is required to be energized first to start the synchronous motor. When such a failure is found, the controller reverses the synchronous motor slightly to bring one of the phase windings which is possible to energize properly to a starting position where the energization of the phase windings is to be initiated to start the synchronous motor in a required direction, thereby ensuring the stability in starting the synchronous motor even if any of the phase windings is failing to be energized.

摘要： An electronic start control device for unidirectionally rotating a permanent-magnet rotor (14) of a synchronous motor (10), comprises: a static switch (22) for series connection to a winding of a stator (12) of the synchronous motor (10); and a position sensor (24) for detecting a position of the rotor (14) of the synchronous motor (10) and for providing a corresponding output (P con ). The device is characterised by including an AC to AC converter (26) having an input (V a ) from an alternating current-voltage source (V ac ) at a fixed frequency connected in series with the stator (12) of the synchronous motor (10), and a single output (V c ) derived from the voltage input (V a ); and an XNOR unit (28) having a first input (G 1 ) in communication with the output (V c ) of the AC to AC converter (26), a second input (G 2 ) in communication with an output (P) of the position sensor (24), and an output (G O ) in communication with the static switch (22). The static switch (22) is controllable by a signal (G con ) output from the XNOR unit (28), so that the rotor (14) of the synchronous motor (10) only rotates in a single direction. Preferably, the AC to AC converter is a phase-shifter (26).

摘要： Problems with accuracy reading position detection signal peaks and minute phase differences in the detection current make motor drive control easily susceptible to differences in motor characteristics. The rotor position is determined based on whether or not a neutral point difference voltage, which is the difference voltage between the neutral point voltage and the pseudo-neutral-point voltage when the motor phases are selectively energized, exceeds a specific threshold value. The phase energized to start the motor is determined based on this determination and the motor is energized accordingly to start. Instead of switching directly from the search step at the initial rotor position to the back-EMF voltage mode, a search and start mode that creates initial rotor speed sufficient to start the motor is executed before entering the back-EMF voltage mode.

摘要： A drive circuit for a brushless DC motor (100) controls at least one of a number of possible operation features of the motor. The drive circuit includes a driver stage for providing a current for a stator coil and varies which of the number of possible operation features of the motor are controlled. The operation features of the motor include inrush current limit control, PWM speed control, analog speed control, detecting a locked rotor condition, setting an alarm following detection of the locked rotor condition, restarting the motor following the locked rotor condition, detecting a low speed condition, and setting an alarm following detection of the low speed condition. Some of the operation features of the motor utilize at least one parameter that defines the desired operation of the feature. The drive circuit further varies the parameters of the operation features without changing the physical configuration of the brushless DC motor.

摘要： The invention relates to a method for starting a sensorless, electronically commutatable direct current motor comprising a rotor (24) that is excited by permanent magnets, the stator (22) having a winding that is in particular three-phase (U, V, W). Said winding can be supplied with a regulated current from a direct current source starting from a stationary state. To achieve this, the control unit (54) that is used first determines the position of the rotor (24) in its stationary state at the beginning of the start-up operation in a range lying below the minimum value of the rotor speed and then generates a regulated start-up supply of current to the phase windings (U, V, W) of the stator (22) by means of the commutator unit (14). Once the predetermined minimum value of the rotor speed has been reached, the control unit (54) receives position signals (∫U3) that are directly derived from the third harmonic wave and/or from additional uneven-numbered harmonic waves of the phase voltages as rotor position signals for a self-commutation of the motor and delivers control signals from said position signals to the commutator unit (14) in order to supply the phase windings (U, V, W) with current during normal operation.

摘要： A control system (100) for a five-phase brushless DC motor (102) including a stator having five windings and a rotor (116) mounted for rotation relative to the windings (114). The windings (114) are adapted to be electronically commutated in response to the rotary position of the rotor (116). The control system (100) includes a sensing circuit (106) to sense the rotary position of the rotor (116) using an optical or magnetic sensor or the back electromotive force voltages in the windings (114). Electronic switches (112) control the flow of current through the windings (114) in response to control signals generated by a control circuit (110) in response to the rotary position of the rotor (116). The control circuit (110) includes start-up logic to start the motor (102). If the rotor (116) is rotating in a wrong direction upon start-up, the control circuit (110) energizes preselected windings (114) and waits for the movement of the rotor (116) to come substantially to a stop and then energizes the windings (114) in a start-up sequence to cause the rotor (116) to rotate in a correct direction. Once the rotor (116) is rotating in the correct direction, the control circuit (110) electronically commutates the windings (114) in response to the rotary position of the rotor (116).

摘要： Die Erfindung betrifft einen elektronisch kommutierbaren Motor, dessen Erregerwicklungen über Halbleiter-Endstufen von einer elektronischen Steuereinheit mittels pulsmodulierter Steuersignale bestrombar sind und dabei im Stator des Motors ein Drehfeld erzeugen, das den Dauermagnet-Rotor des Motors in Drehbewegungen versetzt, bei dem zum Start des Motors in einer Startphase zuerst die Lage des Rotors zum Stator durch gleichzeitige Bestromung zweier Erregerwicklungen positioniert und nach der Positionierung durch Weiterschaltung auf andere Erregerwicklungen in Drehrichtung in Drehbewegung versetzt wird. Ein sanfter Start bei ungünstigen Bedingungen des Motors in der richtigen Drehrichtung wird ohne Lagesensoren dadurch erreicht, dass in der Startphase während einer Positionierphase zwei benachbarten Polen zugeordnete gleichsinnig gewickelte Erregerwicklungen bestromt werden, wobei sich das Pulsweitenverhältnis mit zunehmender Zeit kontinuierlich erhöht, und dass sich an die Positionierphase eine Beschleunigungsphase mit erhöhtem Pulsweitenverhältnis anschließt, in der die in Drehrichtung vorauseilende Erregerwicklung abgeschaltet und die zu dieser gegensinnig gewickelte Erregerwicklung dazu geschaltet wird.
