4.8 V motor A17B-28

coreless

Overview
A17B is a series of coreless (core-free) motors with an outer diameter of 17.4 mm. The series comprises several submodels (for example A17B-43, A17B-42, A17B-33, A17B-28, A17B-19) that differ by length, recommended applied voltage and electrical/mechanical performance. Representative submodel A17B-43 is used in compact electromechanical applications such as electric-fan-equipped masks and other small devices. Dimension drawings and CAD data are available for download per model.
