Motor lead, and wire help

according to the video on youtube, i have to either solder or crimp the wires to the motor leads, i soldered the wire to the lead,(just the little piece) i did not solder it to the whole thing to the motor. i noticed the pieces will not stay on the motor, did i do something wrong ( was i supposed to solder the whole thing together?)

im referring to around 1:50 to 2:30 in the video below

thanks ill try one of those but what do you mean by “the crimps”

oops i forgot about those (i put them on, i mean i forgot what they were called) but i will try to solder it or crimp it, but is it okay if the motor leads are slightly bent, it happened while trying to get the wires to stay on. if not can i but two other motors from your website?

Thanks again for the help

The basic premise is that the wire needs to somehow make contact with the motor leads, either directly using solder, or instead using the crimps provided. You need to press the crimp onto the wire and also press the other end of the crimp onto the motor lead. The connection between the crimp and the motor is not perfect, but once you do it properly, it should withstand a good amount of vibration. The crimps are provided for those who cannot solder, since soldering the wire directly to the motor leads is the ideal solution.

The DFRobotShop Rover hardware bag includes 5 wire crimps - you connect them between the 22 gauge wire and the motor leads.

So long as there is contact between the motor leads and the screw terminals you should be fine. We offer 6V replacement motors. The motor leads are fragile but can certainly be bent.
