CI Kasei of Tokyo, Japan has announced a new family of 12 mm OD Micro Slotless Brushless permanent magnet (PM) motors used in a wide range of applications including battery operated hand-held power tools, miniature compressors, micropumps and small robots.

This four-member motor family features integrated speed control electronics and provides stall or peak torque values ranging from 0.88 mNm (0.125 oz-in.) up 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 CI Kasei models have low current consumption (below 25 mA). The speed constant varies from 2.14 to 2.16 Krpm/V for the C12C-XI models the 2.60 the 2.64 Krpm/V for the C12C-X2 models. All four slotless brushless PM motors are energized at a very low output of 3 V DC.
