    摘要: A braking device for an elevator is disclosed. The device may include a motor, a braking system, a first switch, and a second switch. The motor may be capable of generating a counter-electromotive force. The braking system may move to a disengaged position upon being energized and may move to an engaged position upon being de-energized. The first and second switches may have an open state. In the open state, the switches electrically couple the motor to the braking system so that the counter-electromotive force of the motor may energize the braking system.

    摘要: An exemplary elevator brake device includes a permanent magnet. A core supports the permanent magnet. A first plate is positioned near one side of the core with a first gap between the first plate and the core. A second plate is positioned near another side of the core with a second gap between the second plate and the core. The first and second plates remain fixed relative to each other and are arranged such that relative movement is possible between the core and the plates. An electromagnet selectively influences an amount of magnetic flux across the first and second gaps, respectively, to control a braking force of the brake.

    摘要: A magnetic bearing with reduced control-flux-induced rotor loss includes a rotor 14, and a stator 12 having a plurality of slots S1-S16 around which coils 150-156 of a first Phase A and coils 160-166 of a second Phase B are wound. The winding configuration provides a two pole magnetic field around a rotor/stator gap 15 which is sinusoidal and which can be directed to any location along the gap 15. The configuration minimizes discontinuities or sharp changes in control flux in the gap which thereby reduces rotor losses. Also, the stator tooth gap g1 is minimized to provide smooth flux distribution along the rotor/stator gap 15. More phases and more or less stator slots may be used.

    摘要: An electronic motor drive produces a required motion profile for an elevator door operator actuated by a three-phase, line-powered linear induction motor (LIM) by means of an array of TRIAC switches producing selected forces from the LIM. The TRIAC drive is capable of producing acceleration, deceleration or free coast in either the open or close direction of door operation. When controlled by an algorithm such as a "time-optimal switch point" or "bang-bang" control, the TRIAC drive produces the required motions from the linear induction motor for elevator door operation. The motor windings may be switchable between delta and wye hookups to provide two distinct thrust levels. Phase angle modulation may be used to provide finer control of thrust. The linear motor may be a 12-slot arrangement having four poles and three phases and arranged with flux emanating from the stationary primary (on the car) to a stationary backiron part of the secondary also mounted on the car, wherein the flux passes through a movable copper part of the secondary attached to the elevator door and passing between the primary and the backiron.
