Elevator Motor
When it comes to vertical transportation for buildings, elevators and the elevator motor in them are of great importance. Because with this motor, the process of transporting cargo or people is carried out extremely safely and smoothly.
Working Principle and Basic Task of the Elevator Motor
Elevators are known to be among the indispensables for buildings today. The elevator motor, which can also be defined as the heart of the elevator, has the ability to generate mechanical energy to ensure the movement of the opposite weight and the cabin.
It mostly converts electrical energy into rotational motion and continues to work in this way. Thanks to the motor working together with the drive machine, the cabin moves up and down. The main task of the elevator motor can be seen as moving the ropes that connect the cabin and the opposite weight.
Elevator Motor Types
With the active use of elevators, the motors used in them were also divided into types within themselves.
·Geared (Geared Motors):
These motors are suitable for medium load and speed capacity. They are mostly preferred in medium and small scale buildings.
Gearless Motors:
Known for offering long life and high speed. It stands out with its quiet operation and is used in high-rise buildings.
Hydraulic motors:
Frequently used in low-rise buildings. In these engines, the cabin moves with the piston in the cylinder. Movement is achieved when the electric motor starts the hydraulic pump.
Long-term use is realized with the elevator motor to be selected according to the area of use.
Technical Specifications Affecting the Elevator Motor
It is important to have information about the specifications of the elevator motors that directly affect the performance of the system in order to make the right choice. Power (kW) determines the capacity of the motor. Elevator motors generally operate with 220V, 380V and 50 – 60 Hz systems. While the torque in the motors defines the lifting power, efficiency is among the most important issues in buildings where elevators are used intensively.
Elevator Motor Control
The motors in modern style elevators mostly operate through frequency controlled drives. With the system defined as VFD, energy consumption is optimized and stops and starts become much smoother. At the same time, while the elevator is much safer against sudden load changes, the directions and speeds of the cabins start to work much more safely.
Elevator Motor Maintenance
In order for the existing system to work without any problems for a long time, it must be regularly maintained. If the selected model has a gearbox, it is important to periodically check this box and oil level.
At the same time, insulation tests for the windings in the motor, lubrication of the bearings and control of vibration should not be neglected. In cases of noisy operation or overheating due to long operation, it is very important to contact the experts without wasting time and take the necessary steps to solve the problem before it grows.
