Pittman introduces 26mm brush-commutated DC motors

June 26, 2007 - PITTMAN 26mm brush-commutated DC motors have been designed to deliver more power in a relatively small package. These smooth-running and quiet motors can serve ideally in data storage, medical/biotech, semiconductor, automation, and other applications requiring high performance, long life, and reliability.These iron core DC motors (Series 8690) incorporate bonded neodymium iron boron magnets offering economical alternatives to coreless products. Key features include 7-slot skewed armatures for reduced cogging, resin-impregnated windings for enhanced reliability, and diamond-turned commutators for maximum brush life.They 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.An innovative cartridge brush assembly can reduce audible and electrical noise and significantly improve brush life by maintaining optimum brush force throughout the life of the motor. Motor products can further be customized with optical encoders, custom cables, shaft modifications, shaft-mounted pulleys and gears, ball bearings, RFI suppression components, and other options to satisfy specific application requirements.
