  • Patent number: 9800101
    Abstract: An axial flux motor intended for fixing to a machine comprises a stator stack as well as a rotor installed to rotate with respect to the stator stack, which rotor determines the axis of rotation. The stator stack comprises sectional slots on the side intersecting the axis of rotation, preferably the sectional slots include radial sectional slots or are radial sectional slots and/or there are 6-12 of them. Into each respective sectional slot a fixing part can be installed, which at least in the direction of the axis of rotation shape-locks into the sectional slot in question. The axial flux motor can be fixed to the machine by fixing at least some of the fixing parts to the machine.

  • Patent number: 8205721
    Abstract: A method and an arrangement for controlling a brake of an elevator. In the method a plurality of optional objectives of operation are determined for the elevator; one or more of these objectives is selected at a time to be implemented as an objective of the operation of the elevator by using selection criterion; references for the energizing current of the brake of the elevator that differ from each other and/or references for the closing current of the brake of the elevator that differ from each other are determined; the brake current reference used at any given time is selected so that the selected brake current reference best corresponds to an objective of the operation of the elevator to be implemented; and also the brake of the elevator is controlled by adjusting the brake current towards the selected brake current reference.
