So after some testing with the first motor i found out it can handel the load pretty good. now i have 3 more motors. all working perfectly fine. only point of attention is for the guys of banggood them self. the motors were wrapped in protective foam sheet. unfortunately the protective foam sheet came off and the motors were bouncing around in the plastic bag. Now the engines have a few dents, but they still run
well packed reach less than expected
Great Product And Service Thank You
got here a week earlier then expected can’t wait to get started on building my new cnc machine. these motors look great and are exactly what I ordered
Bought three just in case to solve a skipping issue (jumping to wrong place) with a delta printer. Replaced most suspected original motor. After few test prints going ever faster it did not make any mistakes. I'm 99% sure that it solved the issue and that without tweaking the voltage for that motor. Happy about that. Now about the current. Resistance is supposed to be 1.25 ohms. With the same multi meter original motors (including 'broken') measures around 0.95 ohms. BG ones are higher than 1.4 ohms. There is no way it will have the same amps at the same voltage. Might have thinner but sufficient wires for 2.5A or inadequate wiring or they are relabeled (would influence value for price) . However original 0.95 ohms is wrong too !. Not knowing enough about stepper motor construction and because it just works i give it the benefit of the doubt. Value for price is good enough but very close to competition so 4 stars there.
Продукт ОК
