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 ...

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!

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 ...

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 primary function of the control circuit, however, remains the control of motor speed and torque. The control philosophy provides for fast, accurate control of the amplitude and frequency of the ...

It is often necessary for persons other than licensed electricians to perform minimal electrical work in a commercial or industrial facility. This work must be performed in the same safe manner as all ...

The latest microcontrollers featuring field-oriented control bring higher efficiency to motor-control circuit designs in consumer ...
