AmpFlow E30-150 Brushed Electric Motor, 12V, 24V or 36 VDC, 5600 rpm (4-(Pack))

I purchased this and an AmpFlow S-400-24 400W power supply to drive a custom-built tool spindle for a desktop CNC mill, and with a 1/8" endmill the spindle assembly slices through plastic like it's not even there. This motor is serious for its size, much MUCH more powerful than the motors commonly used on desktop machining equipment (e.g., lathes/mills). It comes well-packed, with plenty of protection.My only concern is the mounting, which is only four 10-32 holes. Seems a bit on the skimpy side for a motor capable of delivering up to about a horsepower. Also, watch the mounting screw depth - you only have about a quarter-inch before you risk touching the top of the armature. These are minor nitpicks, though, and not adequate to justify reducing the score.

I'm using 2 of these with my R2-D3 build. I've hooked them up to a Sabertooth 2x32 and they are working great with a 12V battery, this was just a test.Just note that they are HUGE and have some weight.

This is the fourth AmpFlow E30-150 3" motor I have purchased, like the other ones the performance is outstanding. I use the to drive home made Bonetti style static electric generators, and the performance and reliability of theses units are phenomenal!

Great package, working quite well in my Unimat Lathe rehabilitation.

Very beefy motor.Know what your doing with your circuit. Add a reset-able fuse that matches your anticipated current draw + safety factor.Do your due diligence with your mechanical design/specs. Highly recommend a gearbox.Don't stall this guy.Use proper gauged wires for carrying whatever current you spec.

This is a great small motor

just what I wanted, works fine

Amazed at the power coming out of this little guy. Almost silent as well.
