White Paper: When to Use Steppers for Motion Control

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…

Overview of AC Motor Control Options

Most automatic controls involve 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 in nearly…

How to Choose a General Purpose Motor vs. Inverter-Duty Motor

General purpose motors have been around for many years. They are the workhorse of almost every industry. An inverter-duty motor is a much newer concept that became necessary as motors began to be driven by VFDs (inverters or AC drives). An inverter duty motor can withstand the higher voltage spikes produced by all VFDs (amplified…

How Do AC Motors Work?

AC motors are electric motors driven by alternating current (AC). AC motors are widely used in industry, primarily due to their high efficiency, and their ability to produce constant torque up to the rated speed. AC Motor Types The two most widely used types of AC motors are induction motors and synchronous motors. How AC…
