Motor cuts noise associated with ventilator fans
Sun Tunnel Systems' solar-powered "Fan-Attic" roof ventilator fan utilizes the sun to power a Lo-Cog Series 14000 brush-commutated DC motor manufactured by Pittman
Longer DC motor delivers more power and less heat
A new 22mm brush DC motor with a length of 1.900" can provide up to 40% more continuous torque compared with shorter models, and is ideal for mass data storage and semiconductor processing equipment
In addition to being longer, the SuperBrush has a greater contact area with the commutator.
This decreases current density and reduces brush wear.
SuperBrushes are now available as an option in Pittman Lo-Cog Series 8000 and Series 9000 brush-commutated DC motors.
The SuperBrushes (two in each motor) are housed in unique cartridge brush assemblies, which use torsion springs to ensure even brush force.
These snap-together assemblies permit the SuperBrushes to travel in a true linear motion and provide an ideal brush pressure to withstand the detrimental effects of mechanical wear.
Lo-Cog brush-commutated DC motors from Pittman can deliver performance, reliability, and long service life in a relatively small package for a wide range of power applications, including technology for computer peripherals, imaging, and clinical diagnostic devices.
Depending on the model, these brush motors can achieve speeds up to 10,650rev/min and peak torques up to 410oz-in.
Every Pittman motor is subjected to automated performance testing prior to shipment.
