Stainless Steel GS-775M 20000RPM 775 CNC Spindle Motor with ER11 Collet Set, DC 24V, High Power, Noise Suppression, Electrical DC Motor for 3018 CNC Router Machine

Cumple muy bien su función, potencia de sobra para mi CNC y bien alineado.

Upgrade to the standard and works well

First thing I did was measure the runout. I put the motor in a vise and placed a dial indicator on the side of the collet holder (without the collet cap). Rotating by hand, the total runout is .001". This is very good. The collet holder is glued onto the motor shaft. I suspect this is because they tweak the thing until it's true. I'll bet this is why they give you a holder with the motor. You are purchasing a system. I would recommend that you never remove the holder because it'll never go back on straight. Went to install it on my cheapo 3018 and it wouldn't fit. There is a metal band on the motor, presumably so it will fit larger machines. The band simply snaps off, which allowed the motor to fit into the Z-axis bracket just fine. The diameter of the motor, without the band, is 1.65" I read all the reviews about ramping up the motor, but just for fun, I simply turned it on at full speed with the Candle interface. The motor came on without any issues. However, just for good measure, I will put the ramp-up code into the header section of the gcode generator so it's always there for all NC program files. The motor is very loud, but not because it's unbalanced or out of round. It runs at 20K RPM, so I would expect it to be loud. It isn't any louder than my Craftsman wood router. I was hesitant to purchase this motor, but since Amazon has a decent return policy, I decided to risk it. So far, I'm pleased.

goede balans, zo goed als geen trillingen zeer tevreden over de kwaliteit

Comparé à la broche d'origine qui peine à 8.000 tr/m, là on a vraiment les 20.000 annoncés (mesuré). Pour l'alimentation électrique nécessaire au démarrage de la broche il faut max 4A (mesuré) ensuite à fond elle stabilise à environ 1.5A . Si votre alim fait au moins 5A pas de soucis sinon suivez les préco du démarrage progressif en 2 ou 3 paliers (commandes G-code). Le points négatif, il y en a 1 seul vraiment pour l'instant c'est le bruit, mais bon à cette vitesse. Pour le prix ne pas hésiter, ca change la vie et la qualité du fraisage.
