Abstract
A system includes a permanent magnet generator (PMG) with a generator shaft. An input spline is included on the generator shaft on a first side of the PMG with respect to a longitudinal axis of the generator shaft. A brake is operatively connected to the generator shaft axially between the input spline and an end of the generator shaft on a second side of the PMG opposite the first side with respect to the longitudinal axis.
Claims20
A system comprising:
- a permanent magnet generator (PMG) with a generator shaft;
- an input spline on the generator shaft on a first side of the PMG with respect to a longitudinal axis of the generator shaft, a shear section of the generator shaft axially between the input spline and the PMG along the longitudinal axis and configured to be rupturable to disconnect the PMG from the input spline;
- and
- a brake operatively connected to the generator shaft axially between the input spline and an end of the generator shaft on a second side of the PMG opposite the first side with respect to the longitudinal axis.

A method comprising:
- receiving an input indicative of an overspeed condition for a permanent magnet generator (PMG) having a generator shaft;
- and
- entering into a braking mode based on the input indicative of the overspeed condition;
- wherein the generator shaft includes:
- an input spline on a first side of the PMG with respect to a longitudinal axis of the generator shaft;
- and
- a shear section axially between the input spline and the PMG along the longitudinal axis, the shear section configured to be rupturable to disconnect the PMG from the input spline.
