Pittman brand LO-COG brush-commutated DC gearmotors offer smooth, quiet operation and long life. LO-COG gearmotors feature sintered steel spur gears and are available with several reduction ratios and torque ratings to provide an economical solution for a wide range of applications. Armatures are skewed to minimize magnetic cogging, even at low speeds, and windings are resin impregnated for greater reliability in incremental motion applications. An innovative cartridge brush assembly reduces audible and electrical noise and significantly improves brush life by maintaining optimum brush force throughout the life of the motor. For precision motor control, Hewlett-Packard optical encoders are available in 2 or 3 channel versions with several CPR ranges to meet your position, velocity and direction feedback needs.
Note: all Pittman motors come with flying
leads. The spade terminal option is no longer available.
