Power. Wattage. Energy Consumption. All these terms can be used when discussing electric actuator power consumption. Electric linear actuators that are manufactured by Progressive Automations use DC motors. Depending on the force that the actuator can apply, the size of the DC motor will vary. The higher the force, the larger the DC motor. DC motors with a low current draw will typically be used in the actuator with a lower force rating – same...

When operating linear actuators, there are many specifications users need to understand - Speed, force, current draw, etc., but one element of the linear actuator specification can be tricky to gauge: The noise level. The users often won’t know for sure until they run the application with the linear actuators in them to realize the noise level is too high. It is possible to return your actuators and replace it with an actuator with a lower noi...

If you require a quiet actuator for your application where noise pollution is a concern, the best way is to check out the noise rating along with verifying this value with a decibel chart. Decibels were named to honor Alexander Graham Bell, the inventor of the telephone – the term refers to the intensity of a sound and is often referred to as dB for short. While many people are aware of what the term decibel means, not many can accurately say ...

Have you ever faced a situation where you must connect a high current actuator with a low current control box? Heavy duty actuators like the PA-17 and PA-13 have a significantly higher current draw than the average actuators and many control boxes are not designed to handle such high current. However, we can resolve this by using relays to bypass the current limit on control boxes. In this blog, we will help you with a safe way to use a standa...

Operating an actuator, for the most part, should be easy and straightforward, ...

One of the most important steps in selecting a linear actuator is choosing the appropriate force rating. It is quite simple when the application requires a load to be lifted vertically, wherein the weight of the load being lifted is equal to the force required from the actuator. A more challenging scenario is if you have a hinge-type application, as commonly seen with lids, trapdoors, and windows. In this article, I will use a sample trapdoor...

Lead screws have been widely used to generate linear motion from a rotary motor. It can convert circular motion to linear motion by turning the screw with the nut fixed in place, or turning the nut while the screw remains in place. Today, we will look at two of the most popular screw types in the automation industry: ACME Screws and Ball Screws.   ACME Screw ACME screws use a trapezoidal shape thread to roll on to the lead screw. As the shaft...

There are two methods of multiple actuator control – parallel and synchronous. Parallel control outputs a constant voltage to each actuator, while synchronous control outputs variable voltage to each actuator. The process of synchronizing multiple actuators is necessary when implementing two or more actuators to move at the same speed.  This can be achieved with two forms of positional feedback– Hall Effect sensors and multiple turn potentiom...

Sitting for long periods of time is never a good idea; it can lead to many health issues including obesity, increased risk of cancer, shorter life spans and long term posture problems.  But for some it’s a part of their daily life, primarily those working a desk job that requires sitting at a computer all day. While it is recommended to take breaks and walk away (literally) from your work throughout the day, some people just don’t have the tim...
