There's at least 20 mm of can length that has no rotor engagement and no stator length. There's so much extra winding that's doing nothing but generating heat. It's closer to a 4060 then a 4074, but it's going to use power like a 4074. Review: Good delivery - I have received the delivery on time. Good product.
