Motivation
•
The AHPV from VDS 1.0

electric hub motor,
costing roughly $8000.
(picture on right)
•
VDS 1.0 required a new
electric hub motor to
serve as both a
replacement for the NGM
motor, and as a stepping
stone design for VDS 2.0.
Requirements (Preliminary)
•
10 kW continuous Power
•
90%+ efficiency optimized for 45 miles an hour.
•
Motor weight less than 30 kg
•
Must interface with EV-C200 controller
•
