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 ...

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 ...

In this online engineering specialization, you will master sensor and motor theory and program these devices in a microprocessor system. You will complete courses in sensors and sensor circuit design; ...

When designing a motor control circuit, it’s vital to determine how to deliver the high current required to drive the motor. Designers must choose whether to use monolithic integrated circuits (ICs) ...

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 ...

E-2's main propulsion system consists of two DC motors directly driving contra-rotating propellers. An underwater vehicle with a single propeller is subject to undesirable torque forces, especially if ...

Guest columnist Alfred Hesener, European marketing director at Fairchild Semiconductor, describes how good design of power switches can help reduce losses in motor control circuits. Energy-saving ...

The programmable logic controller (PLC) is a microprocessor-based system that accepts input data from switches and sensors, processes that data by making decisions in accordance with a stored program, ...

Printed circuit boards are used in all disciplines, including motion-control applications. New CAD software helps designers create better schematics and layouts. The days of “electro” and “mechanical” ...

Multiple motors and independent control of each wheel of an EV provides optimal performance and handling. But the complexities of implementation should be understood so that results can match ...

With the right evaluation modules, reference designs and safety-qualified devices, engineers can accelerate time-to-market and achieve functional safety certification for smarter, faster and safer ...
