The low-speed, high-torque motor, featuring a cam-lobe design, employs a MacTaggart Scott heavy-duty motor design. The motor increases component life with two inlet and outlet ports that reduce pressure drops at high power; generating less heat overall.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/motorsdrives/direct-drive-radial-piston-motor" target="_blank">read more</a></p> http://machinedesign.com/motorsdrives/direct-drive-radial-piston-motor#comments Motors/Drives Wed, 16 Apr 2014 18:11:00 +0000 36471 at http://machinedesign.com DC Motors Power Soft-Touch Tattoo Machine http://machinedesign.com/motorsdrives/dc-motors-power-soft-touch-tattoo-machine <div class="field-deck"> Sponsored by MICROMO </div> <div class="node-body article-body">The type of nuanced imagery that defines tattooing today requires more than just precision.
