The top 5 most read articles online, from April 18-24, 2022, for Control Engineering covered induction motors, wireless instrumentation, heat engines, PWM effects and flue-gas monitoring. Links to each article below.

1. Ode to an induction motor

Recite this induction motor tutorial and savor it; even if poetry really isn’t your favorite.

2. Wireless instrumentation communication propels plant processes

Using Bluetooth, WirelessHART and cloud connections, plants and facilities are leveraging increased process and diagnostic data to enhance operational efficiency and decrease downtime.

3. Heat engine with no moving parts designed

MIT researchers have design a heat engine with no moving parts, which could help enable a fully decarbonized power grid in the future.

4. Understanding the effect of PWM when controlling a brushless dc motor

Motion system designers can be challenged when selecting or developing electronics using pulse-width modulation (PWM) to drive brushless dc motors. Heed some basic physical phenomena to avoid unexpected performance issues, along with general guidelines for using a PWM driver with a brushless DC motor. See diagrams, equations.

5. Advancing flue-gas flow monitoring techniques

Considering advantages, disadvantages and process conditions of flowmeter technologies for the flue-gas (stack gas) measurement process engineers can help with selecting the suitable flowmeter for optimum performance.

The list was developed using CFE Media’s web analytics for stories viewed on, Apr. 18-24, 2022, for articles published within the last two months.
