DualDC question

[thtalim]

Hi Tero,
DualDC can work with 2 pcs of BL70-300?
For BL70-300, how many step to make 1 turn?
BL70-300 is 4000 CPR or 1000 CPR?
If I need movement 0.001mm with this drive & coupled with 5mm ballscrew,
is it possible?
How many volt is optimal for this motor?
Is this your largest bldc motor?
thanks
Tonny

"DualDC can work with 2 pcs of BL70-300?"

No.

"For BL70-300, how many step to make 1 turn?"

4000 if drive multiplier is 1.

"BL70-300 is 4000 CPR or 1000 CPR?"

1000 pulses per rev, 4000 counts per rev.

"If I need movement 0.001mm with this drive & coupled with 5mm ballscrew,
is it possible?"

Yes but you need at least 5000 counts/rev encoder.

"How many volt is optimal for this motor?"

Please see motor manual PDF.

"Is this your largest bldc motor?"

Yes. Our distributors have also larger ones.

Hi Tero,
If I use your BL70-300 coupled to ballscrew on Z axis,
When I turn of my machine, will it go down? Must I put brake?
Thanks

Depends on axis weight and friction. Brake can be used to solve the falling if necessary.
