Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

The logic and expansion I/O in MMRs can add a number of functionalities that go beyond its embedded firmware. Most industrial facilities include electric motors that require overload relays for ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

The circuit in this Idea for Design provides three levels of speed control for a dc motor using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from ...

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

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 ...

Seniors Ryan Mort, left, and Jeven Velez work on motor control and relays in the electrical trades program at Jefferson ...

Infineon has added slew-rate control to its Hitfet range of relay-replacing low-side switches. Aimed at automotive and industrial applications, and called Hitfet+, the devices also have enhanced ...
