PCIM: Field-oriented brush-less dc motor controller needs no user code

Allegro will be showing a 5.5 to 50V field-oriented three-phase brush-less dc motor controller than needs no user code at PCIM. Called AMT49406, and first announced for Electronica, will be the first member of the company’s low-sound ‘QuietMotion’ family. A field-oriented control (FOC) algorithm is built-in. “The device optimises the motor start-up performance in a stationary ...

10W relay sits on 4x4mm footprint

Pickering Electronics has introduced a 10W relay that sits on a 4 x 4mm footprint. Standing 12.5mm high, they use reed construction and are called Series 122. The 10W rating comes at 500mA, and maximum contact ratings are 500mA and 200V. There is a single energise-to-make instrumentation-grade sputtered-ruthenium contact, whose initial resistance is 180mΩ, and ...
