Pittman Series 8690 brush-commutated DC motors from Ametek offer smooth-running performance and quiet operation. These 26mm motors suit data storage, medical/biotech, semiconductor processing, automation, and other applications requiring high performance, long life, and reliability. This family of iron core DC motors incorporates bonded neodymium iron boron magnets providing economical alternatives to coreless products. Key motor features include 7-slot skewed armatures for reduced cogging, resin-impregnated windings for enhanced reliability, and diamond-turned commutators for long brush life. The motors are available in three lengths (1.798 in., 1.923 in., and 2.173 in.) and can provide continuous torque output up to 3.17 oz-in, peak torque up to 20 oz-in, and speeds up to 9,000 RPM.
