Components Selection

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: ( 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.

All the system is powered form 26 leads acid battery cells. Why this technology?… costs!.
