Linear Motors are a Better Alternative to Hydraulic Devices

By Michael Adams Subscribe to RSS | June 12th 2012 | Views:

In the contemporary scenario, electric linear motors have emerged as a smarter and better alternative to hydraulic, mechanical and pneumatic motors. The electric motors are far more precise, programmable and offer better repeatability for several critical tasks. In addition, the electric varieties are much easier to integrate into your existing system as they can be easily installed even in restricted spaces. Besides, they offer quiet operation, thus keep your shop noise levels low.

A number of OEMs prefer to integrate electric motors in their products because of these very reasons. Interestingly, all of these factors have also proven to be the motivation for many linear motor dealers and distributors to switch to the electrically driven versions. Overall, the benefits include a long life and less maintenance downtime. A number of users of these devices also observe that the use of electric motors has eliminated the risk of hydraulic fluids that could potentially contaminate certain process applications.

It is important to consider certain factors when you decide to invest in linear motors. In this article we shall discuss a few of them:

•The electric cylinders should be able to withstand your most demanding and critical automation tasks.

•If you have been hitherto using pneumatic motors, then your major considerations during replacement should be a long life and better precision of the electric motor.

•Another vital aspect that you need to consider is a high level of programmability that allows you to fulfill the most accurate automation tasks.

•In addition, linear electric motors should also comprise features such as precise and repeatable force control and positioning.

•Smooth acceleration and deceleration is critical to the success of your product or process. Hence, choosing a rigorously tested and proven motor will address concerns of mechanical slamming. The motor needs to be programmable to meet these requirements.

•On the cost savings front, you need to discuss the energy consumption of your chosen device. Though most modern devices manufactured by reputable firms are energy efficient, it is prudent to check this factor beforehand.

•Finally, there are other minor but crucial factors that you need to discuss. For instance, the noise levels should be low. The device should also have multiple mounting points so that it can be directly retrofitted if the need arises.

In several cases, electric actuators are also used in conjunction with linear electric motors. These products are available in a variety of stroke sizes, ranging from a 5mm stroke to 150mm. There is a unique ‘Soft Land’ function that has been developed recently, and this allows electric actuator to land with a highly delicate and controlled force when being used with glass or other fragile items.

Thus, it is important to purchase linear motors from a highly renowned manufacturer to enjoy a long service life and cost savings.
