    Abstract: A method and an apparatus for damping the vibrations of an alternating current motor is provided. The motor is supplied from an alternating current source with a supply voltage whose frequency is the basic frequency. Additionally the motor is fed with a second voltage having a frequency equal to the basic frequency multiplied by the quantity 2*m*q−1. In the equation, m is the number of the phases of the motor and q is the number of slots per phase.

    Abstract: According to the invention, at least one end of the elevator ropes (8) is fixed to a guide rail (4,7) of the elevator. According to an embodiment of the invention, the whole elevator is so suspended by its ropes (8) that all vertical forces are transmitted by the guide rails (4 . . . 7) to the bottom (27) of the shaft (1). The invention provides the advantages that the elevator is easy to install and that the ical forces are transmitted by the guide rails (4 . . . 7) to the bottom (27) of the shaft (1), permitting a lighter construction of shaft walls.

    Abstract: Damper winding (13) for an elevator motor provided with permanent magnets (14). The damper winding consists of frames (16) surrounding each permanent magnet (14). Each one of the frames is electrically connected to the adjacent frame (16) or the frames are integrated together. The damper winding (13) can be used as a jig for positioning the magnets when these are being fixed to the rotor disc (6). In one of the embodiments, the magnets and damper winding are fixed to the rotor disc by a form-fit interlocking arrangement.

    Abstract: In a system for starting elevator machinery driven by a synchronous motor, current is fed to the motor by a frequency converter and a traction sheave is connected to the motor to move the elevator car with hoisting ropes. The angle of the magnetic field of the stator is determined when the elevator stops. When the motor is started again, a new value of the angle of the magnetic field of the stator is determined on the basis of the change in the load signal. The frequency converter is adjusted so that a magnetic field whose direction corresponds to the new angle of the magnetic field of the stator is generated in the motor.
