Upper plywood frame to
provide support for the motor controller. This raises
the controller to achieve a flow of cooling air over it.
Plywood and metal mesh drive
box covers to ensure fingers can not get access to the
moving transmission or hot drive motors.
Protection must be provided to
prevent access to the internal moving parts of the drive box.
The timber and metal mesh covers also prevent accidental
touching of the drive motors which can get hot when used for an
extended period of driving. The motor controller also generates
heat in normal operation and must be positioned in a cooling
flow of air - this is achieved by the shaped plywood frame which
raises the controller in its position behind the seat.
