Dual-Speed Electric Brush Cutter – SOLIDWORKS Assembly, Gear Train & Drawings

University design project: a complete electric brush cutter designed in SOLIDWORKS with a two-speed gearbox. A high-torque setting handles thick growth and a high-speed default handles grass. What's in it: - 23-part SOLIDWORKS assembly with mates and an exploded view - Stage 1: 16T/60T spur pair (3.75:1 reduction); stage 2: planetary set with 30T sun, 15T planets and a fixed 60T ring - Electromagnetic clutch with return spring to switch between speeds - Two-piece motor housing surface-modelled for injection moulding - Torque and RPM calculated through each stage - Fully dimensioned part drawings, an exploded assembly drawing and a bill of materials - Assembly and exploded-view animations (videos attached) Off-the-shelf parts were modelled from photos and measured with a Vernier caliper.
