Abstract: A determination of the loading state of an elevator system and also a method for determining the loading state of an elevator system is described. The elevator system includes an elevator car and also a motor drive for moving the elevator car. The loading state of the elevator system is determined on the basis of the position deviation of the elevator motor that occurs during the determination of the loading state.

Abstract: An arrangement and a method for supervising the operation of a brake includes a controllable electromechanical brake, including a magnetic circuit with at least two ferromagnetic parts fitted to move in relation to each other. A thrusting force is exerted between the ferromagnetic parts via a spring. The brake includes a magnetizing coil fitted into the magnetic circuit, for forming magnetic attraction between the parts of the brake. The arrangement includes a control of the brake, which includes at least one controllable switch, for adjusting the electricity supply of the magnetizing coil. The control of the brake comprises a supervision of the movement of the magnetic circuit of the brake.

Abstract: The invention concerns a method and an apparatus for controlling a three-or-more-phase motor driven by a frequency converter. In the method, a change-over switch of the frequency converter is controlled to a continuously conducting state and at the same time the phase voltages or phase currents of the other phases are controlled by switching the change-over switches in those motor phases at a switching frequency substantially higher than the frequency of the fundamental wave of the phase voltage or phase current. The apparatus comprises in conjunction with the frequency converter a number of change-over switches, at least one change-over switch for each motor phase. The change-over switches comprise controllable change-over contacts. The apparatus further comprises in conjunction with the frequency converter means for determining the motor phase currents and means for controlling the change-over contacts.

Abstract: Methods and an apparatuses for determining the movement of a synchronous machine are provided. An apparatus for determining the movement of a synchronous machine includes a determination for at least one electrical magnitude of the synchronous machine; a determination of the position error of the rotor of the synchronous machine, which is fitted to determine the position error of the rotor on the basis of the aforementioned at least one electrical magnitude of the synchronous machine; and also a correction of the movement signal of the incremental sensor, which is fitted to correct the read movement signal of the incremental sensor on the basis of the aforementioned determination of the position error of the rotor of the synchronous machine.

Abstract: A method for restricting the output of an electrical drive and for protection of an elevator are provided. The electrical drive includes a motor as well as a power supply appliance of the motor. In the method for restricting the output of an electrical drive the stator voltage vector is restricted to its limit value restricting only the component of the stator voltages in the direction of the q axis. In the protection of an elevator, the elevator includes a machinery brake, a safety brake of the elevator car, and also an electrical drive. The protection method includes determination of at least one limit value, restriction of the output of the electrical drive on the basis of at least one determined limit value, and restriction of the movement of the elevator car on the basis of at least on determined limit value.
