Abstract
A single circuit board assembly for forming a vehicle-motor interface includes a first side of a board with logic modules located thereon. The single circuit board assembly also includes a second side of the board with power modules located thereon. The board comprises a first plurality of layers and a second plurality of layers, the first plurality of layers adjacent the first side of the board and the second plurality of layers adjacent the second side of the board, wherein the first plurality of layers has a first total thickness and the second plurality of layers has a second total thickness, wherein the first total thickness is different than the second total thickness.
Claims8
A motor assembly for a vehicle steering system comprising:
- a motor housing;
- a heat sink assembly operatively connected to an end of the motor housing, wherein the heat sink assembly defines a pocket on a single side of the heat sink assembly;
- and
- a circuit board assembly in operative communication with the motor housing and disposed at least partially within the pocket of the heat sink assembly, the circuit board assembly comprising:
- a first side of a board with logic modules located thereon;
- a second side of the board with power modules located thereon;
- wherein the board comprises a first plurality of layers and a second plurality of layers, the first plurality of layers adjacent the first side of the board and the second plurality of layers adjacent the second side of the board, wherein the first plurality of layers has a first total thickness and the second plurality of layers has a second total thickness, wherein the first total thickness is different than the second total thickness.
