Economical DC Motors

Aug. 1, 2006
Pittman 26mm brush-commutated DC motors are engineered to deliver more power in a relatively small package and promote smooth-running and quiet operation.

Pittman 26mm brush DC motor products (Series 8690) 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 9,000rpm. These iron core motors incorporating bonded neodymium iron bore magnets can serve as economical alternatives to coreless products, says the vendor. Key features include 7-slot skewed armatures for reduced cogging, resin impregnated windings for enhanced reliability and diamond-turned commutators for maximum brush life. 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, says the vendor.
