Vishay Intertechnology recently introduced two new automotive-grade IHTH high-current and high-temperature through-hole inductor in the compact 1500 case size. For automotive applications, the Vishay Dale IHTH-1500MZ-5A (0.47 µH to 4.7 µH) delivers a high-saturation current of 156 A and a low, typical DCR (down to 0.19 mW). The IHTH-1500TZ-5A (6.8 µH to 100 µH) offers…
Vishay’s new thin-film chip fuse is AEC-Q200 qualified
Vishay Intertechnology recently introduced a new fast-acting thin-film chip fuse. For automotive applications, the Vishay Beyschlag MFU 0603 AT is AEC-Q200 qualified and features current ratings from 0.5 A to 5.0 A. The device will be used in electric (EV) and hybrid-electric (HEV) vehicles, where it will provide protection for voltage sensing circuits in battery management systems,…
Stepper Motor : Basics, Types and Working
A stepper motor or a step motor is a brushless, synchronous motor which divides a full rotation into a number of steps. Unlike a brushless DC motor which rotates continuously when a fixed DC voltage is applied to it, a step motor rotates in discrete step angles.The stepper motor can be controlled with or without feedback. Stepper motors work on the principle of electromagnetism. There is a soft iron or magnetic rotor shaft surrounded by the electromagnetic stators. The rotor and stator have poles which may be teethed or not depending upon the type of stepper. When the stators are energized the rotor moves to align itself along with the stator or moves to have a minimum gap with the stator.
