Definitions
- the invention relates to an elevator system.
- EP 599 331 is a conventional linear motor drive system for elevators where the Cabin and a counterweight using ropes over Deflection rollers connected to each other and by several Guide rail pairs are guided in the elevator shaft.
- the Drive in the form of a flat linear induction motor (FLIM) is attached to the counterweight.
- FLIM flat linear induction motor
- the primary elements with the coils are housed in the counterweight.
- a secondary part is used with a conductive material coated tape at the top and bottom of the shaft is attached. The secondary part is arranged so that it runs through the center of the counterweight.
- linear motor has a relatively high electrical output needed.
- the linear motor arrangement described is due to the bilateral arrangement of the primary and Secondary elements in their structure and relatively complex the weight of the cabin is determined by attaching the numerous permanent or electromagnets increased unnecessarily.
- Safety devices, for example for power failure, are due to the ACVF drive only with increased technical effort realizable.
- the invention is based on the object Drive system for lifts of the type mentioned at the beginning propose which does not have the aforementioned disadvantages has and by a simple mechanical structure is marked.
- the advantages achieved by the invention are in essential to see in that through the use a direct drive in the form of a compact, flat, single-sided permanent magnet linear synchronous motor (PM-FLSM) as the elevator drive the required energy and the weight of the drive can be kept small.
- PM-FLSM permanent magnet linear synchronous motor
- a counterweight can be dispensed with. by virtue of its and the compact design of the drive, especially as a result of using strong Permanent magnets, the dimensions of the Elevator shaft can be reduced to a minimum.
- FIG. 1 shows an elevator installation 1 with a cabin 2 a flat permanent magnet linear synchronous motor drive 3.
- the main features of this elevator system 1 are one compact and light drive structure as well as the lack of the engine room and the counterweight due to the Use of the permanent magnet linear synchronous motor direct drive 3.
- the cabin 2 is in a shaft 4 Guide rails 5 guided by guide rollers 6 and serves several floors 7.
- the cabin 2 is one-sided, flat Permanent magnet linear synchronous motor 3 (PM-FLSM) driven.
- a secondary element 10 of the linear motor 3 is equipped with permanent magnets 11 and on one side of the shaft 4 attached.
- One equipped with coils Primary element 12 is on the outside of cabin 2 arranged.
- the brushless, flat permanent magnet linear synchronous motor 3 is carried out in two phases, which is a Reduction of the magnetic coupling between the Motor phases.
- strong permanent magnets 11 such as rare earth magnets, especially neodymium
- the primary element 12 of the linear synchronous motor 3 moves with the cabin 2 along the shaft 4 arranged secondary element 10.
- the secondary element 10 in this sense also serves as a guiding element for the the cabin 2 arranged and equipped with coils Primary element 12.
- Arranged on primary element 12 Bearings ensure that the constant is maintained Air gap L between the primary element 12 and the Secondary element 10.
- this can be done with the Permanent magnet 11 equipped secondary element 10 on the Cabin 2 and the primary element 12 are arranged on the shaft 4 his.
- the drive can also be a three-phase, flatter Permanent magnet linear synchronous motor 3 can be executed.
- FIGS. 2 and 3 show a view and a cross section of the flat permanent magnet linear synchronous motor 3.
- Das Secondary element 10 with the permanent magnets 11 is on several points by means of fasteners 13 with the Bay 4 connected.
- the flat permanent magnet linear synchronous motor 3 has for the drive a pulse width modulator (PWM) with a 16-bit (or 32-bit) single-chip microprocessor and one H-bridge with eight IGBT / MOSFET.
- PWM pulse width modulator
- the regenerative power supply is particularly advantageous High-speed elevators in tall buildings.
- a sinusoidal commutation in conjunction with that of the absolute phase supplied during the initialization phase Position signals allows the generation of a smooth, smooth driving force with minimal force peaks for the flat permanent magnet linear synchronous motor 3.
- Permanent magnet linear synchronous motor 3 In the event of a sudden power failure of the Permanent magnet linear synchronous motor 3 can the coils of the primary element 12 brought into the short circuit position and work as a dynamic brake.
- the in the Short-circuit turns of the person working in generator operation Permanent magnet linear synchronous motor 3 generated Braking force limits the rate of descent of the full loaded cabin 2. For example with a percentage impedance of the primary coils should be 5% Descent speed of cabin 2 is not 5% of the nominal cabin speed exceed. At a nominal cabin speed of 6m / s this value would be due the dimensioning of the coils of the primary element 12 0.3m / s limited.
- This arrangement has the advantage that in the event of a power failure, the cabin 2 without using additional emergency power generators (e.g. batteries) are automatically moved to the bottom floor can.
- one conventional brake for example a normal band or Drum brake.
- a normal band or Drum brake the possibility of using conventional brakes with short, to replace narrow linear motors, which is another compact structure of the elevator system 1 can be achieved can.
- the elevator system 1 described above with the single-sided, flat permanent magnet linear synchronous motor 3 also contains the usual in elevator systems 1 Safety devices (safety gear, Overspeed detector, limit switch, etc.).
