I’ve got a question about creating a motor mount out of 1/2" thick 6061 aluminum plate. I have a 6374 192kv turnigy motor and have measured its shaft to be approximately 25.5 mm in length The diagram of the pulley I ordered (on its way) is shown below. From the drawing below it looks like 16 mm of the 25.5 mm long motor shaft(can’t tell exactly from drawing, can any of you tell? ) will be occupied by the pulley hub leaving around 9 mm of available space for the motor mount plate thickness. I’m basing my design off of torque boards motor mount and their plate is 12 mm thick. I was wondering if 9 mm thickness is enough? I could always let the pulley slide a little further down, use loctite and a grub screw with notched keyway. Let me know what you guys think. I’m thinking I’ll just slide the pulley down enough to where the grub screw will still grip the shaft with a keyway and the plate will be able to have a 12 mm thickness.
