Worcester, Mass. — Allegro MicroSystems Inc. has introduced a full-bridge motor driver designed to drive low-voltage bipolar brushless DC motors. This fully integrated single-chip A1442 motor driver ...

A Coreless rotor means there’s no cogging or preferred rotor position. It has an extremely low current consumption, starting voltage and rotor inertia for extremely fast acceleration and braking. It ...

CUI Devices’ Motion Group has introduced a new model to its AMT commutation encoder family that supports larger motor shaft sizes from 9 mm to 15.875 mm (5/8 inch). The AMT33 series generates standard ...

ServoTek Products Inc. announced the successful application of its TachSyn Series brushless DC tachometer/commutator within industrial motor speed monitoring applications. The high-accuracy TachSyn ...

Permanent magnet direct current (dc) motors convert electrical energy into mechanical energy through the interaction of two magnetic fields. One field is produced by a permanent magnet assembly; the ...
