Motor and gear OK, they were not mounted together as on the picture, and the bussing for the motor axle did not fit. Bussing is 6mm and motor axle is 8mm.
In the item description, the motor and the worm reducer were set items, but when you purchased the option "4pcs / lot Input Shaft Sleeve Shaft Adapter 8mm to 11mm for RV30 Worm Reducer Mounting With Nema 23 Stepper Motor" at the same time, it was not assembled, Also no shaft adapter was attached. The reason for purchasing the shaft adapter at the same time was to prepare for purchasing this 65W motor set (57BLY06930F) after purchasing this 125W motor set, but as it is good to omit it without permission as it purchased additional shaft adapter Absent. Motors and worm reducers can only stop three screws, the machining tolerance is obviously misaligned in one place, the seller's quality is a quality that stops at the end of the Chinese level and is internationally It can be said that the accuracy is rather low level. It was for trial production this time, so I can bear it for practical use, but there are many quality problems to be improved to make it a selling item! !
