Description
maxon A-max motors are an innovative range of high-quality DC motors, equipped withpowerful AlNiCo permanent magnets. The “heart” of our motors is the ironless maxon winding,that has been tested millions of times over. This is the latest technology for compact,powerful and low-inertia drives.
