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 ...

A specialized segment of the electrical construction and maintenance industry, AC motor control is an area that requires specific knowledge in order to troubleshoot motors effectively and ensure ...

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 ...

A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

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 2 depicts the typical timing ...

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 ...

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!

Different types of motors need different types of drivers. Requirements for a variety of applications. Selecting the right motor driver is crucial to achieving the required functionality and ...
