Pittman Series 8690 brush-commutated DC motors offer
smooth-running performance and quiet operation in a powerful small package. These
26-mm motors ideally suit medical/biotech 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 seven-slot skewed armatures for reduced
cogging, resin-impregnated windings for enhanced reliability, and
diamond-turned commutators for maximum brush life.
The motors are available in three lengths (1.798, 1.923, 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 serve to reduce
audible and electrical noise and significantly improve brush life by
maintaining optimum brush force throughout the life of the motor. Motor
products can additionally 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.
