A method for measuring shaft deflection in a turbomachine includes communicating one or more signals from a controller to a plurality of sensing devices positioned on a shaft of a turbomachine across an airgap defined between a rotating antenna positioned around the shaft and a stationary antenna aligned with the rotating antenna in a radial direction to excite the plurality of sensing devices; receiving a parameter of the shaft in a plurality of circumferentially spaced locations from the excited plurality of sensing devices; determining a magnitude of a deflection in the shaft as a function of the parameter of the shaft in the plurality of circumferentially spaced locations; and adjusting a startup sequence or a motoring sequence of the turbomachine based on the magnitude of the deflection.

Tapered shafts for fluid pumps are disclosed. An example apparatus to pump fluid includes a gear, and a shaft including a taper to define a first portion of the shaft having a first thickness and a second portion of the shaft having a second thickness less than the first thickness, the second portion of the shaft between the gear and the first portion of the shaft.
