Electric hub motor enhances EV range (Part 2)

Posted: 16 May 2011     Print Version  Bookmark and Share

Keywords:motor stacks  torque 

To drive the vehicle at speeds faster than 45 km/h (28 mph), a different connecting scheme than shown in Part 1 of this article is required.

The motor stacks are connected in two groups of six stacks. The counter-electromotive force (CEMF) on each group is 63V at 45km/h.

In each group, 16 switches are in series, introducing a series resistance of 3.2 Ω. The current flowing in each stack is (130 – 63) / 3.2 = 21A, generating a motor torque of 260 Nm.
