Wheel Motor

PDF version
Protean Electric, a producer of in-wheel motors, has commissioned a series of wide-ranging studies into the effects and opportunities afforded by in-wheel motors. This includes driving experiments using real vehicles, test rigs and theoretical studies. These studies provide a comprehensive overview of the implications of in-wheel motors in mainstream applications. Two of the studies, specifically into unsprung mass effects, were carried out by Harty and Anderson. They worked in isolation and from very different perspectives, and the results are reported briefly here; conventional “you can’t get there from here” perspectives are severely challenged.
