Abstract: An elevator system (20) is disclosed. The elevator system (20) includes a hoistway (22, 26, a transfer station (34, 36, 42), and a propulsion system (50). The propulsion system (50) may include a moving part (52) mounted on the elevator car (24), and a stationary part (54). An interaction of the moving part (52) and the stationary part (54) may generate a thrust force to move the elevator car (24) in a vertical direction within the hoistway (22, 26) and the transfer station (34, 36, 42). The stationary part (54) may include a first section (80) disposed in the hoistway (22, 26), and a second section (26) disposed in the transfer station (34, 36, 42), the second section (82) having thrust force generation characteristics different from thrust force generation characteristics of the first section (80).

Abstract: A rotor for a permanent magnet electric machine includes a rotor core and a plurality of permanent magnet bundles located at the rotor core. Each permanent magnet bundle includes a first magnet of a first magnetic material and a second magnet of a second magnetic material located radially outboard of the first magnet. The second magnet has an increased resistance to demagnetization relative to the first magnet. A permanent magnet electric machine includes a stator and a rotor magnetically interactive with the stator. The rotor includes a rotor core and a plurality of permanent magnet bundles located at the rotor core. Each permanent magnet bundle includes a first magnet of a first magnetic material and a second magnet of a second magnetic material located radially outboard of the first magnet. The second magnet has an increased resistance to demagnetization relative to the first magnet.

Abstract: An exemplary locking or coupling device includes a plurality of magnets each having a direction of magnetization. A plurality of pole shoe members are positioned between selected ones of the magnets. A moveable support supports some of the magnets and some of the pole shoe members. The moveable support is moveable to selectively change a relative orientation of the directions of magnetization. One relative orientation primarily directs a flow of magnetic flux between the magnets through the pole shoe members and the magnetic flux remains essentially in a plane containing the magnets and the pole shoe members. A second, different relative orientation primarily directs the flow of magnetic flux from the pole shoe members in a transverse direction away from the plane.

Abstract: An exemplary elevator machine frame includes a plurality of support surfaces configured to support at least one of a motor or a brake. A plurality of arms between the support surfaces maintain a desired alignment of support surfaces. At least one of the arms has a first cross section taken transverse to a longitudinal direction along a length of the arm at a first longitudinal location on the arm. That same arm has a second, different cross section at a second, different longitudinal location on the arm.

Abstract: An elevator brake assembly includes a braking fluid for providing a braking force. A first magnet provides a first magnetic field that influences the braking fluid to provide the braking force. The second magnet selectively provides a second magnetic field that controls how the first magnetic field influences the braking fluid to control the braking force.
