Small Coreless DC Motors CL Series 3 to 25 W Coreless DC Motors Smooth-running, optimized-performance coreless DC motors Allied Motions CL series of small Coreless design means no iron loss and higher efficiency compared to coreless DC motors provides iron-core motors maximized performance through the use of high performance permanent Precious metal commutation system in CL29 and CL40 models for magnets, a uniquely wound and low starting voltage formed coreless rotor, and in the CL29 and CL40 a precious-metal Low inertia rotor for rapid response commutation system. CL motors are efficient, having zero iron loss, and Options being coreless, they have no preferred Spur or planetary gearhead with rotor position (cog-free), minimal ratios up to 900:1 torque ripple, and low rotor inertia. Incremental or absolute encoder Available in three diameters (29, 40, High performance DC coreless Integrated tachometer and 66 mm), CL series motors are ideal motors in 29, 40, and 66 mm Ball bearings for CL29 and CL40 for medical devices, small pumps, diameters models mirror/prism drives, and ticket and Power ratings from 3 to 25 W and Custom winding for alternate money dispensers. voltage ratings from 6 to 36 VDC voltages Features & Benefits Custom lead and connector Optimized performance from Coreless rotor design for smooth, configurations coreless winding and high strength cog-free operation Alternate shaft configurations magnets High-strength magnets for maximized performance SPECIFICATIONS Series CL29 CL40 CL66 Rated Shaft Power 3 W 7 W 12 W 25W Bearing System Sleeve Sleeve Sleeve + Ball Ball Commutation System Precious metal Precious metal Graphite-Copper Graphite-Copper Radial Load 5 N (18 oz) 100 N (22.5 lb) (max., 10 mm (0.39 ) from front mount) Axial Load (max.) 0.5 N (1.8 oz) 15 N (3.37 lb) Ambient Temp.
