An axial flux electric can include a motor assembly including a motor shaft, a stator assembly, and a rotor assembly. The stator assembly can include a plurality of stator cores about which a wire coil is wound, wherein one or more of the stator cores includes a stator body with an internal fluid passageway for receiving a cooling fluid.

Electric motor with integrated cooling system

The present disclosure relates to an axial flux motor comprising a stator assembly and a rotor assembly. The axial flux motor includes stator cores having enlarged end plates. The axial flux motor also includes a cooling jacket including fins that extend between electromagnets of the stator assembly. The axial flux motor rotor assembly also includes an air cooling arrangement to provide air cooling to the stator assembly.

A solid-state circuit breaker for a DC system includes a switching module having a first terminal detachably connectable to a DC power source and a second terminal detachably connectable to a load. The switching module has a predetermined plurality of solid-state switches connected in parallel between the first and second terminals. An energy absorbing module has a first terminal detachably connectable to the DC power source and a second terminal detachably connectable to the load. The switching module includes a predetermined plurality of solid-state Transient Voltage Supressors (TVS) connected in parallel between the first and second terminals.

A power converter system includes a printed circuit board having a first connector for receiving low voltage control signals and a second connector for receiving input voltages from one or more power generators and transmitting output voltages to a power distribution unit. Power devices are mounted onto the printed circuit board to manage the input voltages and to generate the output voltages. An enclosure is mounted around the printed circuit board and power devices. The power devices engage interior surfaces of the enclosure forming a conductive heat path between the power devices, the interior surfaces, and exterior surfaces of the enclosure. The heat path conductively transfers heat from the power devices to the exterior surfaces.

A gate drive circuit of a wide band gap power device (IGBT) includes a buffer, a di/dt sensing network, a turn-on circuit portion and turn-off circuit portion. The buffer, responsive to turn-on, supplies a first current via the first current path to the gate of the IGBT, and responsive to turn-off ceases the supply of the first current. The di/dt sensing network receives a feedback control signal representative of a voltage measurement across a parasitic inductance that exists between a Kelvin emitter and a power emitter of the IGBT. The turn-on circuit portion, responsive to turn-on and a parasitic inductance of zero volts, supplies a second current via a second current path to the gate of the IGBT. The turn-off circuit portion, responsive to turn-off and a parasitic inductance of zero volts, discharges a gate capacitance of the IGBT through both the first current path and a third current path.

A current sensing system includes a pre-calibrated busbar, a voltage sensor, a temperature sensor and a controller. The pre-calibrated busbar has a known resistance, a known variation in resistance with respect to temperature and known dimensions. The voltage sensor detects a difference in voltage between a first location and a second location on the pre-calibrated busbar. The temperature sensor detects an ambient temperature of the pre-calibrated busbar. The controller determines a resistance of the busbar between the first location and the second location based on the known resistance, known variation in resistance, known dimensions and the ambient temperature. The controller additionally determines a current flowing through the pre-calibrated busbar based on the difference in voltage and the determined resistance. The current sensing system has numerous applications including using the determined current to control an operating condition of a solid state circuit breaker or a solid state power controller.
