Hello, gentlemen! I have 3 servo motors and I am looking for appropriate servo drives for them. I managed to get a technical specification of my servo motors:
Motor type: T3-0130-60-560 Winding number: 01-00111 Rated Speed: 6000 min^-1 DC Bus Voltage: 560 V Nominal AC Voltage: 330 V Rated Motor Voltage: 309 V Rated Torque: 1,00 Nm Rated AC Current: 1,40 A Stall Torque: 1,30 Nm Stall AC Current: 1,67 A Peak Torque: 5,2 Nm Peak Current: 7,2 A Max. Speed: 12000 min^-1 EMF Constant: 47,0 V/1000 Torque Constant: 0,78 Nm/A Terminal Resistance: 12,7 Ω Terminal Inductance: 21,5 mH Number of poles: 6 El. Time Constant: 1,7 ms Mech. Time Constant: 2,4 ms Thermal Time Constant: 30 min Rotor Inertia: 0,65 kg*cm^2 Intended to be used with EMC2 :) I have 2 questions: 1) can anyone suggest me, where can I get appropriate servo drive? This is for my own machine, my first priority is cost efficiency. It does not have to look good, it is ok to spend additional time on wiring etc. It just has to work reliably. I already looked at 8i20, but it does not fit due to motor's current being too low for the drive, I also looked at Granite Devices, but their drives are working with max 160 VDC. I cannot open KelingInc website (something wrong with my ISP, I got confirmation that the site is actually working), so I have not checked, if they have something that would fit. 2) since closing feedback loop in servo drive is not a requirement for EMC2, I would like to find out, if some motor controller could be used in this situation. Although I would like to avoid using Chinese stuff for several reasons, here is one example, where I cannot understand, if it can be used for my application or no: http://www.hzmgdj.com.cn/product/257548762-209298864/motor_controller.html Thanks in advance for any hints!
