Everyone who has taken an elevator has sometimes felt vibrations in the elevator. These jolts occur both at the time of starting the movement and at the time of stopping, which sometimes disturbs the balance of people. The reason for these shakes is the change in the acceleration of the elevator or the lift motor moving away, and for this reason, the change in acceleration is felt more at the beginning of the movement and at the end of the movement when the engine changes acceleration.
But for years, This problem has been solved by using the elevator drive. The difference between the smooth and quality movement of an elevator, with fast movement and strong shaking in the elevator is the elevator drive. Of course, different drives provide different movement qualities, but overall, the movement quality of an elevator with a drive is much higher than an elevator without a drive. It converts DC voltage and then converts DC voltage to AC voltage with different frequency and voltage; In fact, the elevator drive can control its speed by changing the frequency and voltage it gives to the elevator motor. These conditions in the elevator include slow movement and slow stopping, adjusting the speed at a time other than stopping and moving, as well as accurately adjusting the place where the elevator stops.
All these events happen in a fraction of a second. The elevator drive has the task of controlling the engine speed, that's why it is also called the engine speed controller. The elevator drive can continuously change the engine speed from zero to several times. In other words, its input power with a constant voltage changes from zero to its output power with a variable voltage.
Using an elevator drive has many advantages, below we mention some important advantages of using a drive:
Strong shocks and vibrations have been removed from the elevator, which both relaxes the passenger in the elevator and increases the lifespan of the parts.
Using the drive despite the reasons mentioned Costs can be greatly reduced. In fact, by using the drive to save energy, the cost of purchasing the drive can be compensated very quickly between 6 and 24 months. The lifespan of a drive is more than 10 years, so the amount of energy saving due to the installation of the drive will definitely compensate the cost of its purchase over time.
