Abstract:
The invention relates to a method for determining the operation and/or condition of the holding brake (1) of a traction sheave elevator and to a holding brake (1). The holding brake (1) comprises a brake body (2); a brake pad (3); a brake shoe (4) with the brake pad (3) attached to it, said brake shoe being mounted on the brake body so that it can move between a braking position (I) and a released position (II); a spring (6) arranged to apply to the brake shoe a load tending to move it to the braking position (I); and an electromagnetic actuator (7) arranged to keep the brake shoe in the released position when activated. Using a displacement sensor (8), the displacement between the braking position (I) and the releasing position (II) is measured, and the operational state and/or condition of the brake is indicated by a monitoring device (9) on the basis of the measured displacement.
Abstract:
An elevator drive machine includes a traction sheave and an electromechanical apparatus having at least two electric motors for driving the traction sheave. The traction sheave and the weight applied to it via the elevator ropes are supported by bearings between the stators and rotors of the electric motors driving the traction sheave of the drive machine.
Abstract:
People mover comprising a conveyor track such as an escalator or a moving sidewalk, said people mover being provided with at least one drive apparatus. The drive apparatus comprises an electric motor having a substantially thin construction in the axial direction of the drive apparatus, e.g. a permanent magnet synchronous motor. In addition the people mover comprises a drive wheel which is in conjunction with the rotor of the electric motor.
Abstract:
Holding brake for driving disc lift, comprising: a brake body 1, a movable body 2 which abuts movably against the brake body, a brake lining 3 which abuts against the movable body, an electro-magnet 4 abutting against the brake body, and a mechanical pressing means 5 which removes the movable body from the brake body and presses the brake lining abutting the movable body against the braking surface 6. Further, the holding brake comprises: a regulating body 7, movable relative to the movable body in the moving direction of the brake lining 3, to which the brake lining 3 is fastened, as well as a control means 8 moving the regulating body 7 relative to be movable body when the air gap 9 between the brake lining 3 and the braking surface 6 is adjusted.
