    摘要: The present invention is applied to a tribological pair comprising two metal pieces, a first of them having a movable contact surface which provides friction in relation to a respective contact surface of a second of said metal pieces. According to the present invention, the first metal piece has its contact surface defined by a coating formed: by a first surface layer in a material harder than that of the first metal piece; and by a second surface layer, disposed onto the first surface layer and in a material defining a coating which reduces the chemical affinity in relation to the contact surface of the second metal piece of the tribological pair, in order to provide, to said tribological pair, a lower friction coefficient in relation to the tribological pair deprived of said coating.

The parameter depends upon the rotation of the motor.One also foresees the use of a digital filtering technique, to eliminate the effects of the modulation on the control method. The filtering is characterized by the arithmetic mean of the last k samples of each average electric voltage (fN), these samples being synchronized with the period of modulation.

    摘要: A method for controlling and protecting electric motors, specially permanent magnet motors electronically actuated by a control system. The system includes a three-phase inverting bridge, in which the position of the rotor can be monitored by using a position detector physically attached to the axle or through the tension induced in the coils by the magnet, in order to correctly control actuation by the control system. The present invention is also directed to a system for controlling electric motors and an electric motor system. The system includes continuously reading the position detector until a minimum expected time has passed. After the minimum expected time has passed, there is continuous reading of the position detector until a maximum expected time has passed to detect if a position change of the rotor is sensed.
