Mounting the motor

Written by admin. Posted in AC Traction Motor

Mounting the motor to the transmission involves two primary tasks:

  1. Adaptor plate design/construction – motor face to transmission bell housing face
  2. Shaft adaptor design/construction/installation – mounts flywheel to motor shaft

Here we have placed them shaft-to-shaft, level, and in their proper orientation to look for any conflicts on the bolt placement around the bell housing relative to the electric motor.

The primary thing to look for is places where a bolt from each side of the adaptor plate share the same location or overlap slightly, interfering with each other.

We are happy to report that there are no bolt location conflicts in the planned orientation. If there were a conflict, the motor could be rotated slightly one direction or the other to allow clearance, as long as the shafts remain in concentric orientation.

Plan changed

Written by admin. Posted in Charging System

The original plan was to combine the DC/DC converter heatsink (presently air cooled) with this water cooled charger, since the cooling resource is available to be shared. Because of the non-square inner compartment shape, the DC/DC converter will not fit, even with it’s air cooled heat sink removed. This will force it to the trunk, mated with the 12V standard battery that it will be delivering current to anyway. There is a good location for it there and will not cause a noise issue from it’s fan since the trunk is isolated from the interior.

We think we are close to delivery, maybe a week or two, we’ll see.

Good news, the dimensions have been reduced in each axis since we had created the model used for original fitting. That makes this job basically a done deal. It’s a perfect fit.

At the same time, we were able to workout the coolant plumbing sequence/routing for all 4 components that share the cooling system.
