Brush DC Motors Feature Quiet Operation

April 2, 2008 9:53 am | Product Releases | Comments

AMETEK Technical and Industrial Products introduced the PITTMAN Series 9000 brush-commutated DC motors that deliver quiet and smooth operation for equipment used in data storage, medical/biotech, semiconductor processing and automation applications. Their modular construction promotes customization to satisfy specific requirements. These motors, with 2-pole stators, incorporate 7-slot skewed armatures to minimize magnetic cogging (or reluctance torque), and they enable smooth and quiet running performance. Commutators are diamond-turned after armature assembly to ensure optimum concentricity and long brush life. Windings are resin-impregnated for greater reliability in incremental motion applications. Standard features include ceramic magnets, silicon steel laminations, copper graphite brushes and heavy-gauge steel housing. Speed, voltage, current and torque characteristics can be varied to meet application demands.
