## Description

Compact 390 type motor for DIY micro drilling projects and precision applications, operates at 6-24VDC with 12V recommended and offers speed proportional to voltage up to 26000 rpm. 2.3x14mm shaft for easy coupling to the chuck, 27.6mm housing and 47mm length for integration in small spaces. Easy mounting with 16mm clamps, 100g weight for stability.
Motor type 390, specially designed for DIY projects of electric micro drilling, compatible with power supply between 6 and 24VDC (recommended 12VDC), offering the possibility of reaching rotation speeds proportional to the applied voltage.
It is recommended to observe the polarity and rotate the shaft in one direction because the brushes will deteriorate faster if it is rotated in the opposite direction (plus is marked on the connector).
With compact dimensions and a wide range of speeds depending on the applied voltage, it is ideal for applications that require precision and efficiency.
