Brush-Commutated Smooth, Quiet Motors

Pittman Series 9000 brush-commutated DC motors can deliver quiet and smooth operation over time for equipment used in data storage, medical/biotech, semiconductor processing and automation applications, among others. Their modular construction promotes customization to satisfy specific requirements. These motors with two-pole stators incorporate seven-slot skewed armatures to minimize magnetic cogging (or reluctance torque) and enable smooth and quiet running performance.

Commutators are diamond turned after armature assembly to ensure optimum concentricity and long brush life, and windings are resin-saturated for greater reliability in incremental motion applications. Other 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" to 3.35") and can achieve a maximum continuous torque rating of 6.9oz/in at speeds up to 6,070rpm, depending on model. Speed, voltage, current and torque characteristics can be varied to meet application demands.
