Cored vs Coreless DC Motors - Which Should You Choose?
A brushed DC electric motor converts electrical energy into mechanical energy using Lorentz Law, which states that “a current-carrying conductor placed in a magnetic field will experience a force”. This force can be used in a variety of ways, such as in a linear actuator to convert rotational motion into linear motion.
Progressive Automations offers a variety of linear actuators containing either a cored or coreless DC motor, but which type sh...

How Are Linear Actuators Made?
A linear actuator creates motion in a straight line. It is widely used in machine tools and industrial applications. Recently, with the rise of electric linear actuators, more and more industries have begun to use them to automate their applications. For example, linear actuators are used in the renewable energy industry to tilt panels towards the sun for optimal exposure and in the medical industry to actuate hospital beds.

Getting Started with Arduino and PA-12
The PA-12 is a high precision actuator that can be controlled with Arduino. This PA-12 introduction guide will feature control methods and implementation with the PA-12 Arduino API.
There are two versions of the PA-12. The PA-12-R has a coreless DC servo motor and RS-485 communication protocol. The PA-12-T has a cored DC servo motor and TTL/PWM communication protocol.
Getting started with the PA-12 and Arduino will depend on the version of PA-...

Assessing Washdown Actuators in the Food & Beverage Industry
In the food & beverage industry, production lines must follow practices and cleaning procedures such as washdowns to maintain good hygiene standards and meet consumer safety requirements. The use of linear actuators for driving the motion found in food & beverage production equipment is invaluable, however, these actuators must be able to handle the high temperature and water pressure during washdowns. This article will cover the impor...
