Toshiba Elevator and Building Systems Corporation (TOSHIBA) is an established industry leader in elevator and escalator manufacturing with advanced technologies, including Ultra High Speed Elevator which travels at 1010m/min. We provide wide range of products, such as SPACELUNI machine roomless series, ELCOSMO with compact machine room and NewELBRIGHT high speed series.
Permanent magnet synchronous motor (PMSM) has the characteristics of small size, simple structure, high power factor, reliable operation, easy heat dissipation and easy maintenance. It has been widely used in machine tool servo system, elevator drive, electric vehicle propulsion, air conditioner compressor, etc. [2] .
30/09/2011 · The motor used escalator is induction motor we can use this in different forms like with magnet,gears and ac motors... The motors which are used in elevators are 3phase induction motor.
The motor will rotate either clockwise or counterclockwise based on how you want the elevator to move. There is a pulley attached to the motor, and as it rotates, the pulley either rewinds or releases some of the string that is also attached to the elevator. To keep track of where the elevator is: There is a photocell on each floor. When the ...

Elevator Control System is the system responsible for coordinating all aspects of elevator service such as travel, speed, and accelerating, decelerating, door opening speed and delay, leveling and hall lantern signals. It accepts inputs ( button signals) and produces outputs (elevator cars .
The elevator system consists of a Simulink® model and a user interface (UI). The model contains two Stateflow charts: Elevator System models the core logic that delegates incoming requests from the UI to the nearest available elevator car. This chart contains a pair of atomic subcharts that implement identical logic for the cars.
The motor component of the elevator machine can be either a DC motor or an AC motor. A DC motor had a good starting torque and ease of speed control. An AC motor is more regularly used because of its ruggedness and simplicity. A motor is chosen depending on design intent for the elevator. Power required to start the car in motion is equal to ...
