The four-member family of 12-mm OD micro slotless brushless permanent magnet (PM) motors offers integrated speed control electronics to provide stall or peak torque values ranging from 0.88 mNm (0.125 oz-in) to 1.14 mNm (0.161 oz-in). The shorter C12C-XI-S and C12C-X2-S models use sleeve bearings and operate at 6,480 rpm and 7,920 rpm, respectively. The ball bearing models, C12C-X2-S-B and C12C-X2-S, are used in applications that handle heavier-application mechanical loads. All models have low current consumption (below 25 ma) and are energized at an output of 3 Vdc.
