Greetings; The function generator arrived today, so I have the potential PSU, one 2M542 driver, and an A.T. KL23H266-20-8B motor setup to test how is the best way to run it.
The first thing I notice is that its maximum current draw, when the driver is set for a hair under 2 amps, is actually at about 350 rpm. I think my Greenlee digital amprobe fades below that frequency, and I have no clue what its response when the excitation frequency is well above 60hz. Anyway, with 46 volts available, with this 8 wire motor wired for series as a 4 wire, nominally 1.81 amps of drive according the the dip switch chart on the driver, and the rpm divisor set at 6400/rev, I can drive it to somewhat above 300Khz giving a hair over 2812 rpm. But the inductance sure seems to be crippling it as it is only drawing about .43 amps at that speed. So I may go back out and see how it runs wired in parallel. I also note that the opto's in the driver are about done at 750Khz when its set for a 25600 per rev divisor. The motor stops and doesn't even squeek when its sitting there stalled. Its just locked up as if the drive failed. But I haven't tried it as a paralleled coil drive yet. But I'd sure like to find an AT chart showing this motors nominal performance. I struck out at www.automationtechnology.com, getting the impression I was not even on the right companies site. Has anyone a better URL? Thanks everybody.
