yea, that might be an issue ( heat ) but keep in mind the gearing dictates the amp draw , so were the drill 3-1 drive to the spindle , it would run cooler even at high rpm.. Other motor setups get expensive .. I used to build ( and still do ) electric scooters and go karts for a hobby.. What ive found between that and building cnc machines ( just finished the cnc lathe ) theres no cheap way to get all the features of a good controller/motor combo without actually buying a good controller/motor combo lol.. You either lack variable speed, need to buy a vfd, lack torque , or burn up motors while running an decent controller with a cheap motor and the list goes on.. Anyway , for a small mini lathe , a drill actually checks a lot of boxes for dirt cheap , assuming it had some external cooling , and an actual pot knob adjustment . Just food for thought when you start setting up for the final motor combo
Since you are this close, pm me your addy and I’ll try to get you a motor w/ controller sent. You’ll probably have to wing it on the pulleys, I think I’m out. The treadmill motors can run at some ridiculously high rpm, so I generally gear lower and get a bunch of torque at lower speeds yet still have my higher rpm’s. I’m sure I’ve mentioned it but I don’t use the flywheel on the motor. It’s not needed for our machines. It does however have the cooling fan cast into it. I use a delco alternator fan (correct id for shaft). Dave
Alright then. I need to do some figuring on pulley sizes that would be optimal. What rpm range you looking for at the spindle? I run mine ALL the time and don’t have a clue what my rpm is…lol Dave
Motor mount styles and a nameplate/size pic. They are pretty small for the power they produce. Dave
nice , whats the spindle out of ?
