Abstract
The utility model relates to a magnetic suspension elevator which uses a long stator of a linear motor to attract the elevator directly and essentially consists of a cabin (2), an elevator wellwall and a motor. The motor group is a three-phase linear motor; wherein, the three-phase linear motor consists of the long stator (3), a motor winding and an iron core (1); the long stator (3) is vertically arranged at the left side and the right side of the elevator wellwall; the motor winding and the iron core (1) are arranged at the left side and the right side of the cabin (2) relative to the long stator and corresponds to the long stator by a certain gap; in addition, a permanent magnetic steel is arranged in the cabin; and in case that the power is off, the magnetic steel can attract the long stator and slides down slowly and the cabin can not fall into the deep. When the power in a magnetic suspension elevator well is off, a clamp can automatically extend out, thus preventing the elevator from falling to the bottom. The long stator can be used as a magnetic suspension rail when being vertical and can be used as a rail of a conveyer belt and a rail of a magnetic track fly cart when being transverse.
Description
Technical field
The utility model relates to the elevator of the round direct motor drive elevator rail structure in a kind of elevator field, particularly relates to a kind of magnetic suspension lift that overcomes the restriction in height of cable wire elevator.It is to utilize to be arranged on car machine winding and iron core and to be arranged on that long stator is the repulsive linear electric motors on the hoistway wall, induction generates an electromagnetic field mutually, the induction long stator drives the car oscilaltion rapidly, and become a kind of new design that quite has practicality and progressive, be suitable for the industrial community wide popularization and application.
