I would like to extend the wires coming off of the EMG 30 motors in the RD02 drive system, 12 Volt. I searched your product section and came up with this: robotshop.com/100mm-f-f-6-pin-jumper-wire.html Would this fit into the connectors of the EMG 30 motors? This is a f-f wire assembly…do you sell a m-f assembly that fits the EMG 30 wires?
I extended the wires on one of the motors by 8 inches by splicing in regular wire, but now I don’t get any response when I run the program. (I extended all 6 wires on just one of the motors.) I am running this code:
robot-electronics.co.uk/files/arduino_md25_serial.ino
and using this setup: robot-electronics.co.uk/htm/arduino_examples.htm#MD25 RD02 Motor Controller serial (the MD25 RD02 serial setup). When I plug both motors in, I get no reading on the LCD03. When I plug only the un-spliced motor in, I do get a reading on the LCD03, but the motor does not rotate when I upload the program. Do you think the problem is with my splicing, or that the 8 inch extension caused too much of a voltage drop…or something else? I did get both motors to run and the LCD03 to read correctly before I spliced the wires.
Since the splicing did not work, could you give me the part number of that cable assembly? I think it is Molex…maybe they can make a m-f cable to extend the wires. Is it a 6-pin PicoBlade connector?
Actually, on second thought, could I possibly get an EMG30 specially made with 15-inch wire lengths? I would need two motors, each with a 15-inch wire assembly.
I went back and redid my splices and now both motors run. However, now the LCD03 does not display. It may just be another bad splice. I may take your suggestion and solder the wires together. Thanks for your help thus far…the important thing is that the motors run…
Unfortunately custom orders for motors are not possible (these motors are mass produced and having an employee stop to make one custom order would significantly increase the price), but why not simply add a connector (6 pin JST) to extend the wire length? Alternatively, you can remove the connector which comes with the unit and solder new wires.
Unfortunately that choice of wire or any other wire will not be suitable for mating with that cable mainly because of the pin spacing (even if you used long male headers to convert one end to a male connector)
A good choice would be to splice the wires and extend them with regular lengths of wire. However, keep in mind the more you extend the power wires, the higher the voltage drop you will get across them.
