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 ...

A seemingly trivial circuit layout can be problematic because of the higher than usual currents that are common in motor-control circuits. Although the circuits that monitor three legs are slightly ...

Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position control is necessary. Motors of ...

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; ...

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 ...

Thin film, thick film, wirewound and solidcomposition resistors offer different thermal dissipation and surge-withstand characteristics, which impact their abilities to handle overcurrent and ...

KAWASAKI, Japan--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has started mass production of "TB9103FTG," a gate driver IC [1] for automotive brushed DC motors, ...

Dopamine transmission is critical for exploratory motor behaviour. A key regulator is acetylcholine; forebrain acetylcholine regulates striatal dopamine release, whereas brainstem cholinergic inputs ...
