Pittman Lo-Cog 6000 and 8600 series brushed DC motors feature resin bonded, neodymium iron boron magnets, skewed armatures and innovative cartridge brush assemblies.

Pittman Lo-Cog 6000 and 8600 series brushed DC motors feature resin bonded, neodymium iron boron magnets, skewed armatures and innovative cartridge brush assemblies for precise control, low magnetic cogging and long life for a wide range of motion control applications.

Lo-Cog 6000 and 8600 series motors are aimed at applications requiring the power of an "ironless rotor" or "coreless" motor, without the associated cost.

Neodymium magnet technology provides more power than most other DC motors of similar size and suits a wide range of demanding motion control applications such as mass data storage equipment, computer peripherals, office automation, imaging systems and medical diagnostics equipment.

These motors feature a cartridge brush assembly that reduces audible and electrical noise and significantly improves brush life by maintaining optimum brush force throughout the life of the motor.

Skewed windings minimise magnetic cogging, even at low speeds, and windings are resin impregnated for greater reliability in incremental motion applications.

With diamond turned commutators and precision ground stainless steel shafts, these high performance motors feature copper graphite brushes and thanks to their modular construction, are available with a wide range of standard options including alterative brush material, ball bearings for the 6000 series and optical encoders with wide choice of angular resolutions.

For production quantities, windings may be customised to carefully match customers speed and torque characteristics and nonstandard encoders, gearboxes, custom cables, connectors, specialised shafts, pulleys, gears and other mechanical modifications can be easily accommodated.

The 6000 series motors have an effective outside diameter of 22mm and are available in two standard lengths of 32 and 48mm producing maximum continuous torque of 5.7 and 14mNm, respectively.

The 8600 series feature 26mm outside diameter in three lengths of 46, 49 and 55mm with respective continuous torque ratings of 14, 17 and 22mNm.

Both ranges feature no-load speeds between 7000 and 9000rev/min.

The 6000 series is available as part of the MotionExpress fast delivery programme in 6, 12 and 24V versions with "next day" delivery of several variants, some with planetary gearboxes with gear ratios between 4:1 and 169:1.
