Motorization of the 1/32 OpenRailway EMD SW1500

myminifactory

This is a gearbox designed to power Daniel Noree's outstanding EMS SW1500 locomotive (https://www.myminifactory.com/object/12438).\r\nIt employs a low RPM 580 motor. All axles and shafts are supported by ball bearings.\r\nMotorizing both trucks will generate more torque for better performance.\r\nNotes:\r\nEverything is printed in ABS plastic. The frame and the cover are printed with a 0.2 mm layer height, while the gears are printed with a 0.1 mm layer height.\r\n\r\nThe truck utilizes six ball bearings (3x7x3 mm) and three millimeter steel axles (57 mm long each). The central shaft is seventy millimeters long.\r\nThe gears feature a back slot to accommodate an M3 nut, which securely locks them onto the shafts using an M3 grub screw. For optimal performance, it's recommended to smooth the teeth with a triangular file.\r\nThe motor fits snugly into the truck turret, thanks to a small amount of filing or sanding for a precise fit.\r\nThe truck in action
