The Role Of Variable Speed Drive In A Gearmotor's Durability

February 06, 2023

Gearmotors are used in a variety of applications, from consumer products to industrial equipment. They are reliable and durable, but their performance can be improved with the addition of a variable speed drive (VSD). In this article, we will explore the role of VSDs in gearmotor durability and how they can help extend the life of your motor system. Read on to learn more!


How does a variable speed drive ensure the gear motor's longevity?

When it comes to the durability of a gearmotor, a variable speed drive (VSD) can play a key role. By definition, a VSD is an electronic device that allows for the speed of an electric motor to be adjusted. In terms of a gearmotor, this means that the VSD can help extend its life by reducing wear and tear.


There are two main ways in which a VSD can achieve this: firstly, by avoiding high starting currents; and secondly, by matching the motor speed to the required load. Let's take a closer look.


When an electric motor is started, it draws a large amount of current from the power supply. This high starting current can cause problems such as voltage dip, which in turn can lead to premature failure of electrical components. A VSD can help avoid this by soft starting the motor, that is, gradually increasing the voltage applied to the motor over time until it reaches the required operating voltage. This not only protects the motor from damage but also reduces stress on the whole system, resulting in increased reliability and lifespan.


Secondly, a VSD can match the speed of the electric motor to the required load. For example, if a gearmotor is driving a conveyor belt that is not fully loaded, there is no need for the motor to run at full speed. By running the motor at a lower speed, less energy is consumed and therefore increases its durability.


The role of a variable speed drive in a gear motor's durability is undeniable. By controlling the motor output, it can reduce wear and tear on the components, enabling them to last for longer periods and increasing their overall reliability.
