摘要： The invention concerns a method which consists in supplying a first alternating signal to one end of at least a stator winding, at a specific frequency, and in recovering a measurement signal at the other end of said winding, said measurement signal being supplied to electronic processing means adapted to extract an information concerning a periodic variation of the stator winding effective inductance. Said variation is a function of the rotor angular position. By alternatively performing such measurement on the stator windings, it is possible to extract three periodic curves (SPCA, SPCB, SPCC) defining a zigzag curve (70) for accurately determining the rotor angular position.

摘要： The invention relates to a relay support device for an electric motor for the arrangement of a number of relays on a front face of an electric motor, on which winding connectors and signal lines for the electric motor are provided. The relays serve for switching and interrupting the power supply to the motor windings. Said relay support device comprises a support component, embodied such as to extend over the front face of the electric motor and comprises at least one, preferably several chambers for housing and positioning the relays. A connecting chamber is integrated in the support component for the electrical connection of the winding connectors and the relays. A sensor board is preferably further integrated in the support component, to which the signal lines from the electric motor may be connected. High-current-carrying electronic components for controlling the motor windings of the electric motor and low-current-carrying electronic components for signal recording from the electric motor can be pre-assembled in a single component using said relay support device.

摘要： Is disclosed a rotary position detector comprising a rotor rotatable in synchronism with a motor and a rotary position detecting portion for generating a voltage signal corresponding to an angular position detectable as a magnetic flux change with rotation of the rotor, wherein the detecting portion is disposed with respect to the rotor within a range of an angle of 2 π /n, where n is the number of pairs of poles of the motor, and a motor provided with the same rotary position detector, wherein a motor drive control circuit assembled together with the detecting portion at the same place on the motor. The rotary position detector is easy to manufacture, small and light, easy to mount on a motor and easy to connect with a motor drive control printed circuit. The motor provided with the same rotary position detector is also described.
