Brush-Commutated DC Motors provide quiet operation.

Press Release Summary:

Designed with 2-pole stators, PITTMAN® Series 9000 incorporates 7-slot skewed armatures to minimize magnetic cogging and enable smooth, quiet-running operation. Commutators are diamond turned after armature assembly to ensure concentricity, while windings are resin-impregnated for reliability in incremental motion applications. Offered in 6 lengths from 1.82-3.35 in., motors can achieve max continuous torque of 6.9 oz-in. at speeds up to 6,070 rpm.

Pittman 'Series 9000' Brush DC 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 2-pole stators incorporate 7-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-impregnated 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 6.9 oz-in at speeds up to 6070 rpm, depending on model. Speed, voltage, current, and torque characteristics can be varied to meet application demands.

Customization options include planetary or spur gearboxes, optical encoders, alternate brush materials, brakes, cables, connectors, modified shafts, and RFI suppression or special configurations.
