Definitions

  • the present invention relates generally to elevators but more particularly to a scalable multi-car cyclic magnetic elevator cars with gravity linear electric generator including a repulsive magnetic guide assembly to minimizing undesirable movements of the elevator via non-contact magnetic repulsive system. It also uses rotary permanent magnet array magnetic wheel with reinforced gear wheels for attractive magnetic propulsion rather than using an electromagnetic wheel or linear motor propulsion system that is dangerous if used on vertical propulsion because electromagnets are dependent on electricity to attain attractive propulsion, and due to gravity the elevator cars needs to be vertically secured which is what is offered by this present designed magnetic elevator propulsion system with rotary passive magnetic array propulsion wheel.
  • This elevator system is scalable because of the nature this elevator system has to offer, meaning it can accommodate a multiple car system on mono-directional shafts and will deploy or add elevators cars on a need to use basis making this economical elevator system compared to conventional elevator systems.
  • a conventional traction type elevator includes a cab mounted in a car frame, a counterweight attached to the car frame by a rope or cable, and a drive assembly including a machine driving a traction sheave that engages the rope. As the machine turns the sheave, friction forces between the sheave and the rope move the rope and thereby cause the car frame and counterweight to raise and lower.

  • This non- contact propulsion system means less maintenance is necessary and wear and tear of the gear tooth wheel is remote.
  • it uses a servo-motor or any types of motors and an attractive magnetic electromagnetic wheel or propulsion system to attain magnetic propulsion that will bring the elevator up and down faster, safer and intelligently using servo motors to control motion. Because the propulsion mechanism is now mounted on the moving elevator compartment, thus eliminate the need for cables or ropes and therefore with this important breakthrough, it is likely that this new magnetic elevator system can adopt a multi-car elevator system.
  • the advantage of having a multi-car elevator system is that it allows more than one elevator car. or cab that can travel along the length of the cyclic elevator mono-directional shaft. That means that in the future, fewer shafts will be needed to cater multiple cars thus decongesting the traffic flow of the passengers that moves to and pro in the building using at least only two shafts rather than using multiple shaft system.
