ELECTRICAL THE ENGINEERING PULSE OF AFRICA Motor Drive:
9
Controller Throttle Input Signal Hall Effect Sensor from Motor Switching Circuit ELECTRICAL THE ENGINEERING PULSE OF AFRICA Controller:
10
PRO’s 3 phase No transmission required CON’s Does not meet all specifications PRO’s 3 Phase Meets all specifications CON’s Transmission required Therefore the Brushless DC Motor was chosen Hub MotorsBrushless DC Motors Motor Specifications: Torque, Voltage, Current, Power THE ENGINEERING PULSE OF AFRICA ELECTRICAL
11
Fuel Cell: - No complex humidification - No heavy air compressor - Wide power range - No liquid cooling of the stack - Quick and easy to replace a single damaged cells - 5kg THE ENGINEERING PULSE OF AFRICA MES 1.0
12
Capacitors: - Depending on demand of motor (Torque) - Depending on backup system - Maxwell 350F - 2.7V - 10 year life span - Lightweight construction (63g each) - Higher energy capacity then batteries ELECTRICAL THE ENGINEERING PULSE OF AFRICA
13
ELECTRICAL THE ENGINEERING PULSE OF AFRICA Fuel Control topology:
14
Semi Monocoque: - Internal ribs for strengthening - Maximizes strength to weight ratio - Allows integration of sub-componets Drive train: - Reduction box - Solid drive shaft MECHANICAL SkinFormer / Ribs Bulkhead THE ENGINEERING PULSE OF AFRICA
15
Steering: - Rear wheel steering - Universal rotary steering system - Freewheel bearings (Front Axle) Suspension: - Alternative methods than conventional shock absorbers - Involving composite material properties THE ENGINEERING PULSE OF AFRICA MECHANICAL
16
Wheels: - Front wheel 20” - Back wheels 14” Brakes: - Hydraulic disc brakes (used on mountain bikes) - High braking power - Lightweight MECHANICAL THE ENGINEERING PULSE OF AFRICA
