I think the main advantage is that there are only three halfbridge stages needed to drive this motors.Originally Posted by bunalmis
I have a router running with three KT60KM06 Trysin motors salvaged from
photocopiers. The step angle is 0.6degr. so running in halfstep mode 0.3degr.
I use the HA13532 controller and the SLA7023 driver, from the original controller, to make them working and they doing verry well. Reasonable speed and no problem with resonance till now. The router works 8" by 11" and is mostly used for milling PCB's.
Last week I ran into a other 3Phase driver board from a copier with a STK673-010 driver. One complete driver block with microstepping possibilities. I did not test is yet but I will in the comming weeks.
I do not have experiance yet with 2phase motors on a machine so I cannot compare them with the 3phase motors but they are running verry smooth with me.
