Brush DC Motors/Gearmotors have skewed armature design.

Press Release Summary:




Series 14000(TM) brush-commutated DC motors and gearmotors feature 11-slot skewed armatures that minimize magnetic cogging. With modular construction, motors are available in 7 lengths and achieve peak torques to 410 oz-in. and speeds to 4,230 rpm. Series GM14000 gearmotors, available in 7 lengths with 4 ratios from 5.9:1-218.4:1, provide peak torques to 175 or 500 oz-in. Commutators are diamond turned after armature assembly, and windings are resin-impregnated.

PITTMAN® Series 14000(TM) Brush DC Motors and Gearmotors Feature Skewed-Armature Design



PITTMAN® Series 14000(TM) brush-commutated DC motors and gearmotors feature 11-slot skewed armatures designed to enhance performance by minimizing magnetic cogging (or reluctance torque). This series of motor products offers quiet and smooth operation for a wide range of power applications, including computer peripherals, imaging, and clinical diagnostics.

PITTMAN Series 14000 motors are available in seven lengths and can achieve peak torques up to 410 oz-in and speeds up to 4,230 RPM. Series GM14000 gearmotors are available in seven lengths with four ratios from 5.9:1 to 218.4:1 and can provide peak torques to 175 oz-in (standard) or 500 oz-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 customized with alternate brush materials, encoders, timing belt pulleys, brakes, cables, connectors, modified shafts, and RFI suppression or other special configurations to meet application requirements.
