When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Today's motors are increasingly driven via electronic controls, which offer better control of speed, position, and torque, as well as much greater efficiency, rather than via direct connection to ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

In this article learn about options for measuring current in motor control applications, the strengths and challenges of these options, and how using precision current measurement can optimize the ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

[Afroninja] is back with another great tutorial on basic electronics. This time around he’s explaining H-Bridge motor controllers and how they work! Even if you don’t have much (or any) experience ...

The fundamental circuit shown in Figure 1 generates timing for a two-phase stepper motor from an oscillator, as well as a direction (forward or reverse) signal. Figure... The fundamental circuit shown ...

Embedded exhibition sets out to simplify DC motor control circuits Richard Wilson Simplifying the design of DC motor control circuits was the aim of a number of microcontroller announcements at last ...
