Re: Rigid tapping Setup

Uwe, Hello. nice work as usual! thanks for sharing. would be great to pan the camera over to the Acorn CNC12 screen during these demos to prove that its an Acorn that is running the show:-)) If it would be Linux CNC I have had to talk 15min how difficult rigid tapping was to set up, an then looking...

Re: Spindle Motor on PM-30MV Integration into Acorn

Yes, I have a 2.2kw Delta EL VFD on my beltgrinder, it limits output amps, but if you can not bring 18.5 A to the Baldor, torque will be less also... My JMC servo with driver and wiring for 559€ and build in resistor can go with 0.2 s acceleration and deceleration time. Thats way faster the Delta ca...

Re: Spindle Motor on PM-30MV Integration into Acorn

They draw nearly 19A at startup, do you need a 20A VFD to run them?

Re: Stepper Motor Rattling at High Speeds

Have you tried to run the driver with the Leadshine Pro Tuner software?

Good way to analyze which is the max rpm of the motor, but should be over 2000 if the motor is wired correctly to the driver.

Re: Spindle Motor on PM-30MV Integration into Acorn

My mill was outfitted with spindle bearings, not tapert roller Bearings as usual.

But i replaced the chinese stuff with good quality FAG bearings an Klüber ISOFLEX NBU 15 spindle grease.

No need to by a 1000$ kit.

But you can also get roller bearings which work up to 12000 rpm with NBU 15

Re: Spindle Motor on PM-30MV Integration into Acorn

Thats really a good discussion. 1.5kw is the rated consumption of motors normaly 3 phase motors are asycronous and 3phase servos are syncronous in this range The higher efficiency of syncronous drives is what makes the slight difference in torque on the drive shaft For the combos with driver / VFD I...
