    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: 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.

    Abstract: The invention discloses a protection of an elevator and a method for protecting an elevator, in which the elevator comprises a machinery brake (7), a safety brake (8) of the elevator car (10), and an electrical drive (1) comprising an elevator motor (3) and a power supply appliance (2) of the elevator motor (3). The protection of the elevator comprises restriction of the output of the electrical drive (1) on the basis of the determined limit value (27, 28) for the stator voltage and/or the stator current of the elevator motor (3) and restriction of the movement (12, 29) of the elevator car (10) on the basis of at least one determined limit value (13, 14, 30, 31, 32) for permitted movement of the elevator car (10). At least one limit value for permitted movement of the elevator car (10) is determined at least partly on the basis of the limit value (27, 28) for the stator voltage and/or the stator current of the elevator motor (3) and the elevator car (10) is fitted to move with a restricted movement during the restriction of the movement of the elevator car (10).
