摘要： The invention relates to a method carried out with simple means for determining the position of the rotor in a sensorless and brushless multi-phase electric motor (1) in addition to a device particularly suitable for carrying out said method. According to said method, a phase voltage (Uv) on the clamping side on said motor phase is to be detected after clamping a first motor phase (V) from the reference potentials (UZ,M) of an intermediate circuit (7) during a detection period (TE), via which the detection period (TE) determines a peak value (Uv*) of the detected phase voltage (Uv), the peak values (Uv*) are to be compared to the comparative value (Uc), and a positon signal (SP) is to be produced when the peak value (Uv*) exceeds the comparative value (U0). The comparative value (Uc) is then determined digitally such that it corresponds to the value of the phase voltage (Uv) at a zero crossing of a voltage (UVind) induced in the first motor phase (V) or an increased or lowered value in relation to a predefined correction value (DeltaQ).

摘要： A motor drive circuit compares a back electromotive voltage generated in a coil of the motor with a middle point voltage of the coil to detect a zero cross point and outputs a back electromotive detection signal. According to the back electromotive detection signal, the motor drive circuit controls ON/OFF of a plurality of switching elements so as to adjust current flowing into the coil of the motor. Prior to the detection of the zero cross point, a window signal which is outputted for a period of the back electromotive detection signal multiplied by a predetermined coefficient sets the switching circuit to a high-impedance state. With this configuration, it is possible to adaptively set the length and the timing of the non-drive period of the switching circuit according to the motor rotation state. ® KIPO & WIPO 2009

摘要： A device and a method for controlling a motor using a fuzzy velocity compensator are provided to control the motor through a program without additional hardware by rapidly accomplishing a command velocity according to a parameter change or disturbance. A device for controlling a motor includes a fuzzy velocity compensator(160) and a fuzzy controller(170). The fuzzy velocity compensator compares a command velocity with an estimation velocity to calculate an error and then corresponds to a velocity change or a load change while minimizing a velocity estimation error. The fuzzy controller compares the estimation velocity with the command velocity by estimating a velocity and a position of an IPMSM(Interior Permanent Magnet Synchronous Motor) rotor by using a current detected through a current detector(150), compares the current with an actual current to change a voltage by a voltage equation, applies the voltage to an IPMSM through an inverter, and supplies an estimation position to a current controller(130).
