Elevator Engine
The invention of the elevator is rooted in the history of the 3rd century BC during the Archimedes period, which is known as the oldest. It is stated that the Roman architect Vitruvius, who is known to have built the first lift, started with the work of the cabins on the hemp rope.
At the beginning of the 19th century, German inventor Werner Siemens applied the electric motor to an elevator for the first time and development continues with developing technologies.
The elevator engine works by converting the mechanical energy required to provide the movement of the lift and converting the required mechanical energy into electrical energy. The elevator motor is an electric motor that allows a lift to move. In general, it is produced in various types and sizes as a result of criteria such as weight, load amount, speed and distance it can carry. (As the latest technology, Mitsubishi Electric company optimises lubrication as much as possible with the ‘Constant Magnetic Field Gearless Motor technology, resulting in size reduction, energy and space saving in motors)
How does the Elevator Engine Work?
1. In the elevator engine, electromagnetic coils generate a magnetic field. These coils are wound around an iron core, which is a magnetic material.
2. When electric current is applied to the coils, a magnetic field is generated around the coils. This field magnetises the iron core and starts to generate magnetic force.
3. The magnetic force generated is used to rotate a magnetic drum or pulley inside the motor. The drum and pulley are wound by a lift cable.
4. Thanks to the force coming to the drum and reel, it rotates the secondary part of the motor and now the car inevitably starts to move in the elevator cabin.
5. The speed and direction of the motor is controlled by the input voltage of the motor and the strength of the magnetic field. The movement of the elevator is monitored by the speed control systems and these systems ensure that the elevator stops at the designated stops and operates safely.
What are the types of Elevator Engines?
Elevator motors have different types, types, types and sizes, and are now known to be made today in special designs according to the ever-evolving workload and needs.
· Direct Current (DC) Elevator Engine: Direct current elevator engines are the preferred engine feature of elevators to provide high and linearity. It is generally preferred as high power and industrial type.
· Alternating Current (AC) Elevator Engine: Alternating current lift motors are widely used in smaller lifts used in homes, offices.
· VVVF (variable speed frequency) Elevator Engine: This type of engine is used to control the speed, direction and braking characteristics of the lift.
· Pneumatic Elevator Engine: Pneumatic motors work by using air pressure. Such motors move the elevator cable using compressed air.
· Hydraulic Elevator Engine: These motors work mechanically using hydraulic fluid, basically using fluid pressure to move the elevator cabin.
Elevator Engine Parts?
Drum or Pulley: A drum or pulley is needed that wraps the elevator cable and provides the movement of the elevator, it is connected to the output shaft of the motor and rotates using the magnetic field force of the motor.
Elevator Cable: The elevator cable is wrapped around the drum and pulley, this cable allows the elevator to move up and down. This cable is produced in various sizes according to the speed and weight according to the cabin it will carry.
Control systems: This system is used to control the movement of the elevator and is an important system that controls the speed and acceleration, direction and position of the elevator.
Gear Box: Thanks to the gear box, the elevator cable achieves movement and the power of the motor is transferred to the drum or pulley, as a result of which the lift achieves motion acceleration.
How to do Elevator Safety and Elevator Maintenance?
Elevator safety is very important, failure to take precautions and necessary maintenance can cause serious problems and irreversible consequences. Elevator safety is a legal obligation in accordance with the elevator directives that introduced EU standards in 2003.
The elevator consists of a large number of moving mechanical parts, especially the cabin, the constant movement of these parts can bring some negative situations, wear due to friction, aging, etc. can cause problems in situations. Periodic maintenance is a part of elevator safety and is indispensable. The first degree cause of elevator accidents is that the cabin does not stand in the lift shaft in accordance with the floor.
