Hi Traumflug
i want to know if the whole torque curve is reduced with 50% when voltage is reduced withe same %
To be realistic 480 volts , 4A is a bit OTT, as said, max is about 25x rated voltage, with this motor about 100V, but driver can do as stated max 45V so that is the practical limit
The built in charge pump in the L6470 can compensate for BEMF (partly)
The point is that rpm (rps) and pps are linked, therefore you can reach corner speed very quickly when you start microstepping-right? As per my original question
So if we do a simple 200 step/revolution, accoording to the torque curve we start to loose torque over 800pps, 4 rps- direct drive with 8 teeth T5 pulley yields 160 mm travel/sec
At >5000 pps, torque is about 25% of peak
Looking for 300mm/sec, =8 rps/ 1600 pps so my options are bigger motor or higher voltage
Microstepping again makes this worse?
Appreciate if you comment on my other questions
Thx
