The sizing step gave us the information about the brushless motor type and characteristics; SMB142 30 15 5 24 2I 65 2 with this speed/torque curves:
With the information about torque and speed we have identified the drive type: SLVD17ND. For all the details concerning these two components you can see the manufacturer web site: (www.parker.com). Each single motors should be transfer mechanically the movement to the tire and this task can done by a belt thru pinion and crown wheel together working on the dedicated interface. Considering that we don’t have any gearbox we should find an appropriate gear ratio and the value of 2,5 comes out as a result of the sizing step (we should verify it on the test steps). All the system is powered form 26 leads acid battery cells. Why this technology?… costs!.
