Brush DC Motors Designed for Smooth and Quiet Operation
Mon, 06/30/2008 - 5:07am
Motors can deliver quiet and smooth operation over time. Their modular construction promotes customization to satisfy specific requirements, adding versatility. The motors with 2-pole stators incorporate 7-slot skewed armatures to minimize magnetic cogging (or reluctance torque and enable smooth and quiet running performance. Standard features include ceramic magnets, silicon steel laminations, copper graphite brushes, and heavy-gauge steel housing. Motors are available in six lengths (from 1.82 inches to 3.35 inches) and can achieve a maximum continuous torque rating of 6.9 oz-in at speeds up to 6070 rpm, depending on model. Speed, voltage, current, and torque characteristics can be varied to meet application demands.
