1. An aircraft propulsion unit, comprising:
- an electric motor;
- at least one accessory unit used for operating the electric motor;
- an inverter module, the inverter module including a plurality of inverters for powering the electric motor and the at least one accessory unit, the inverter module including an inverter module housing having a first region and a second region that is separated from the first region, the first region and the second region including redundant inverters;
- and
- a cooling system coupled to the electric motor and the inverter module, the cooling system comprising a coolant path for circulating a coolant through or adjacent to the electric motor and the inverter module.
