Brushless motor C17B-18

DCcompactsmall-size

Overview
The C17B series are brushless DC motors with an outer diameter of φ17.4 mm, offered in multiple submodels (examples: C17B-23, C17B-22, C17B-07, C17B-25, C17B-24, C17B-16, C17B-13, C17B-18, C17B-06, C17B-09). These compact motors are designed for small fans and other air-moving devices (e.g. electric fan-equipped masks). Per-model electrical and mechanical data are provided to support selection and integration.
