Because AC motors are essential workhorses for industry, designers need to understand their applications to make detailed selections, such as single-phase or three-phase styles. Electric motors are a fundamental force for creating powered motion in any type of equipment. Initially developed in the 1800’s and refined significantly over the years, electric motors are now available…
DC motors provide a flexible and effective motive force for many machine and automation applications. Although direct current (DC) motor technology dates from the early 1800s, and other motor types have been developed since then, DC motors remain the best option for many applications. DC motors can be obtained in tiny consumer-grade form factors suitable…

Opening the Automation Door
A home project to upgrade a garage door system with an AutomationDirect PLC, HMI, and VFD made the equipment run better, added many functional features, and provided extensive visibility and diagnostics. Industrial automation components have many applications outside the factory. Home and hobbyist projects can be a great way for learning how to execute larger…
The safe torque off function built-in to modern VFDs significantly improves the integration of emergency stops. Kevin Kakascik, Technical Marketing Engineer with AutomationDirect, wrote an article for the May-June 2021 issue of Industrial Equipment News. The article, titled Motor Drive Safe Torque Off Improves Equipment Safety, explains the capability and how to use it. Here’s…
Stepper motors can be the best option, even for precision motion control applications, while avoiding the expense and complexity of servo motors. Standard AC induction and DC motors can only produce basic motion control, and servo motor solutions provide exceptional performance but drive up costs and complexity. For many motion control applications, stepper motor solutions…

Most automatic controls involve AC motor control in some way, especially in factory automation. Applications such as pumps, fans, robotics, and conveyors use motors. Whether general-purpose 3-phase ac motors, which are great for simple on/off systems, or the inverter-duty motors specifically designed for operation with variable frequency drives (VFDs), one could say that motors are ubiquitous…
