LO-COG(R) 26MM Brush-Commutated DC Motors From Pittman Feature Skewed Armatures To Reduce Cogging
HARLEYSVILLE, PA, May 15, 2002 -- LO-COG® 26mm brush-commutated DC motors available from Pittman feature 7-slot skewed armatures for reduced cogging and resin-impregnated windings for enhanced reliability. These smooth-running and quiet iron core motors can serve as an economical alternative to coreless products and can offer long life for a wide range of applications, including medical and office-automation equipment.
LO-COG 26mm brush motors (Series 8690(TM)) are designed in three lengths (1.798", 1.923", and 2.173") 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.
Motor features include two-pole permanent magnet stators, which are constructed of bonded neodymium iron boron magnets to promote enhanced operating performance, and diamond-turned commutators for maximum brush life. An innovative cartridge brush assembly is designed to reduce audible and electrical noise and significantly improve brush life by maintaining optimum brush force throughout the life of the motor.
LO-COG 26mm brush motors can be customized with optical encoders, custom cables, shaft modifications, shaft-mounted pulleys and gears, ball bearings, RFI suppression components, and a wide range of other options to satisfy specific application requirements.
