Lo-Cog Series 14000 brush-commutated DC motors and gearmotors from Pittman feature 11-slot skewed armatures designed to enhance performance by minimising magnetic cogging even at low speeds.
Lo-Cog Series 14000 brush-commutated DC motors and gearmotors from Pittman feature 11-slot skewed armatures designed to enhance performance by minimising magnetic cogging (or reluctance torque) even at low speeds.
This family of brush DC motors and gearmotors offers quiet and smooth operation for a wide range of power applications, including computer peripherals, imaging, and clinical diagnostics.
Lo-Cog Series 14000 motors are available in seven lengths and can achieve peak torques up to 410oz-in and speeds up to 4230rev/min.
Lo-Cog Series GM14000 gearmotors are offered in seven lengths with four ratios from 5.9:1 to 218.4:1 and can provide peak torques to 175oz-in (standard) or 500oz-in (with high-torque wide-face gears).
Speed, voltage, current, and torque characteristics can be varied to meet specific needs.
Commutators are diamond turned after armature assembly to ensure optimum concentricity and long brush life.
Windings are resin-impregnated for greater reliability in incremental motion applications.
Copper graphite brushes are standard.
Modular construction enables these motors and gearmotors to be customised with alternate brush materials, encoders, timing belt pulleys, brakes, cables, connectors, modified shafts, and RFI suppression or other special configurations to meet application requirements.
Every Pittman motor is subjected to automated performance testing prior to shipment.
