OverviewThe A17B series of coreless DC motors (outer diameter Ø17.4 mm) manufactured by C.I. TAKIRON. These miniature coreless motors are intended for compact ventilation and fan applications such as electric fan-equipped masks and other small devices. Multiple sub-models offer different lengths, voltages and performance characteristics. Product media (detailed images, outline drawings and a demonstration video) and CAD data are available to support design and evaluation.

Other notable A17B series model entries (summary)The series comprises many variants (examples: A17B-44, -43, -42, -41, -40, -39, -37, -35, -34, -33, -30, -29, -28, -27, -26, -25, -24, -23, -22, -21, -20, -19, -18, -17, -16, -11, -08, -07). Variants differ primarily by motor length, applied voltage and resulting performance parameters (speed, current, torque, efficiency and output), enabling selection for specific compact ventilation and micro-mechatronic applications.
