  • Dual propeller drive system for a ship
    Patent number: 11046404
    Abstract: A drive system is provided for propelling a ship through water. The drive system has two propellers. The propellers are coaxial so that one propeller engages the incoming water first, and the other propeller engages the water after it passes through the first propeller. The drive system has a stator that causes a first rotor to rotate. The first rotor is connected to, the first propeller to cause the first propeller to rotate. The first rotor also causes a second rotor to rotate. The second rotor is connected to the second propeller to cause the second propeller to rotate.
    Type: Grant

  • Windings for an electric machine
    Patent number: 10951080
    Abstract: There are disclosed winding configurations for electric machines that employ printed circuit board (PCB) type end winding connections to enable an automatic and faster assembly of the electric machines. The winding configurations provide a compact PCB-type end winding arrangement with an optimal fewer number of turns/bars in the slots of the board to complete the loop of winding connections. The winding configurations have application in three phase or multiple phase inner rotor or outer rotor electric machine topologies.
