In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.

Complete, unambiguous, and correct software requirements, including safety or security requirements. Correct and consistent design specifications without extraneous functionality. Compiler-produced ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

This article describes ongoing internal project activities at eInfochips in the control systems domain for applications in motor and engine controls aimed for aerospace and automotive segments.

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...
