Suzuk-E – Suzuki Electric Bike Active Cooling, LED Dimmer Circuit and CNC Stencils

The Suzuk-E Electric Bike build continues. The last time they did some cool Gear Casting using CNC and Foam. This time they added some active cooling to the electric motor and used a CNC machine to make some stencils, constructed a custom LED Dimmer Circuit and lots of other fun projects.

“Over the course of several road and trail runs the motor temps were topping 100F as measured in the center of the outer steel magnet casing. If this were July, I’d be quite pleased, but this is Feb/March and the temps never were above freezing, one day was minus 10C. To continue along with the paint theme I opted to draft some simple stencils to do the lettering. The mill was set to 25 Inches per minute feed rate running a 0.020″ cutter set to a depth of 0.030″. The cut is a little ragged but certainly passable.”
