![]() Step 3: Creating the Motor Component Plate - PDB and Stand Off Hardware Holes:ĭrafting the Power Distribution Board hardware holes:ġ. As a rule the motor booms width should not be much more than the propellers, for a racer of this size that equals 12mm. Tangent Constraint allows the center to move independently of the top and bottom arc points, resulting in more fidelity of your design.ĩ. Click the arc and drag it to the original position. Repeat the process for all remaining arcs by re-selecting the arc / tangent constraint, select the corresponding motor mount.Ĩ. Select an arc tool, from the Sketch Pallet click on Tangent Constraint and select a motor mount. To add more creative control over your design it is good practice to now Tangent Constrain the arc tool points to their motor mounts.ħ. Repeat the process for the bottom arc to complete the motor boom layout.Ħ. Draft a new arc from top left motor mount to the correspond position of the top right motor mount and drag the arc in to the center rectangle as illustrated.ĥ. For top and bottom arcs use the circle construction line as a guide. From upper left Motor Mount, in line center with the bottom slot tool, draft a 3 point arc down to the bottom left motor mount, in line center with it’s top slot tool, click and drag the arc to just touch the center component plate rectangle.ģ. From drone center draft a rectangle, type in the values of 160mm vertical by 45mm horizontal. Step 2: Creating the Motor Component Plate - Component Plate and Motor Booms:ġ. The result will be motor mounts that are perfectly square. click on Drone Center Point, change the default setting from 3 to 4 and click ok. From the tool’s dialogue box check to be sure all 48 elements are selected. Right drag select the complete motor mount.Ģ1. The 1st motor mount is now complete with a motor screw layout to allow good wire flow from the motors to drone center where they will connect to the Power Distribution Board (PDB).Ģ0. ![]() Change the default setting from 3 to 4 and click ok.ġ9. Click on center point and select the motor mount circle center point.ġ8. From the tool’s dialogue box check to be sure all 11 elements of the slot tool are selected. Right drag select the motor mount slot.ġ7. Adjust the top and bottom arcs to allow distance from the top circle perimeter and the cent circle diameter.ġ6. ![]() Using the 25mm dimension line as a guide, draft a slot just off the center motor shaft circle. From motor mount circle center draft out a new circle and type in 5mm.ġ4. Create a center circle which will become a hole to allow the motor’s drive shaft to spin freely.ġ3. Use the 25mm dimension line as a guide, adjust so it is perfectly vertical.ġ2. From the 45 degree line intersection draft out a new construction circle and input 25mm. Create the motor mount, Sketch / Center Diameter Circle. Note: When drafting out a Motor Mount it is key is to assure that the motors are equal distance or square from each other.ġ0. Select the Circle and hit “X” on your keyboard to convert the line to a construction circle. Hit “X” on your keyboard to convert the line to a construction line.ĩ. Draft another line tool between the two and type in 45 degrees. Measure out a 45 degree arc from the center vertical and horizontal lines.Ĩ. Draft out a horizontal line from center to just past the right of the circle perimeter and hit “X” on your keyboard to convert the line to a construction line.ħ. Draft a vertical line from center to just past the top of the circle perimeter and hit “X” on your keyboard to convert the line to a construction line.Ħ. Drag out and input 210 mm in the diameter dialog box.ĥ. From world center draft a 210 millimeter circle. Select the bottom plane so your view orientation is facing down.Ĥ. In the Model Module / Sketch Menu / Create New Sketch.ģ.
