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 ...

Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...

Reversing Motor Circuits provides a comprehensive overview of the various means used to reverse electric motors. Motor control circuits use various control devices to change the direction in which a ...

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 ...

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 ...

The Allen-Bradley Branch motor control components have been revised by Rockwell Automation. According to the company, this move was made to update systems where components are used to turn on and off ...

Locomotion is a complex motor act that, to a large degree, is controlled by neuronal circuits in the spinal cord. Using a systems neuroscience approach in several model systems of non-limbed and ...
