Pittman series 8000 motors are available in 53, 56 and 62mm lengths and achieve speeds up to 9020rev/min at continuous torque for standard motors at rated voltages.
Pittman series 8000 brush-commutated DC motors feature a seven-slot skewed armature design to minimise magnetic cogging (reluctance torque) and promote smooth and quiet operation.
This family of brush DC motors offers performance, reliability and long life for a wide range of power applications in industries such as data storage, medical and biotech, semiconductor and automation.
Pittman series 8000 motors are available in 53, 56 and 62mm lengths and achieve speeds up to 9020rev/min at continuous torque for standard motors at rated voltages.
Speed, voltage, current and torque characteristics can be varied to satisfy particular application needs.
Standard features include sintered bronze bearings, two-pole stator, ceramic magnets, heavy gauge steel housing, silicon steel laminations and copper graphite brushes.
Commutators are diamond-turned after armature assembly to promote optimum concentricity and long brush life.
Windings are resin-impregnated for greater reliability in incremental motion applications.
Modular construction enables their assemblies to be customised with alternate brush materials, optical encoders, timing belt pulleys, brakes, cables, connectors, modified shafts and RFI suppression or other special configurations to meet application demands.
Motors can be equipped with planetary or spur gearboxes.
