摘要： The brushless electric motor (M) is provided with switching means (Q1-Q6) for selectively supplying current to the armature windings (U, V, W) of the motor (M) from a DC-power supply (1) The switching means (Q1-Q6) are controlled by measuring the back-electromotive forces developed in the windings (U, V, W) during operation and comparing these measurements with a high and low reference voltage, in such a way that each time a measured back-electromotive force with positive slope crosses the high reference voltage or a measured back-electromotive force with negative slope crosses the low reference voltage, a commutation signal is generated to commutate the switching means (Q1-Q6), this provides a highly simplified control of the switching means.

摘要： A permanent magnet rotating machine control system and method includes an estimator that calculates an estimate of the machine's rotor speed. The estimator receives energization feed back from the machine in a first rotating reference frame and outputs the rotor speed estimate in a second rotating reference frame. A controller receives a rotor speed demand and the rotor speed estimate, and outputs control signals for controlling energization of the machine in response to the rotor speed demand and rotor speed estimate signals. The first rotating reference frame rotates at the commanded rotor speed, and the second rotating reference frame rotates at the estimated actual rotor speed.

摘要： A magnetic-pole position detecting apparatus for a synchronous motor includes an arithmetic section outputting six voltage vectors having equal amplitudes and equal-interval phases to a circuit section as a voltage vector command. The circuit section applies the voltage vectors to a synchronous motor, outputs a trigger signal to a detection section each time after finishing the application of each voltage vector, and detects each phase. Thereafter, the arithmetic section calculates and outputs magnetic-pole positions at every 60/(2k) degrees (where k is a natural number based on the detection current. Each voltage vector is applied for a time period sufficient for each phase winding to be magnetically saturated in an order so that the phases of each voltage vector either increase monotonically or decrease monotonically. Tn detecting the magnetic-pole positions, the arithmetic section generates an added current value that is a result of an adition of current values for each combination of every 180-degree different phases from among current values that are in phase with the voltage vectors. The arithmetic section specifies magnetic-pole positions based on the added current values.

One system includes a meter (14) coupled to a motor terminal (A, B, C) and adapted to produce a range of digital output values (44) representative of a motor terminal signal from which a back EMF signal is derivable. The system (10) also may include a controller (16) that is coupled to the meter (14, 42) and is operable to monitor the range of meter output values and to compute a motor commutation time based upon a monitored local minimum meter output value and a monitored local maximum meter output value.
