DC Motor Internal Brush – 2020 Upgrade Notice

posted in: Uncategorized | 0

Dear Sherline Customers,

We recently upgraded our DC motor by switching from external brushes to internal brushes. The new motor with internal brushes (P/N 45475) will mean more torque and more consistent running, not to mention a longer life for the brushes. (Internal brushes can be changed only by factory installation.)

We decided to make this change for a few reasons. CLICK HERE to learn more about this decision.

Thank you,
The Sherline Team
