Various embodiments of the teachings herein include a canned electrical rotating machine or liquid pump. The machine or pump may include a can made of a first material. The first material comprises, at least in a proportion of more than 50% by weight, a composite material with high-modulus or ultrahigh-modulus (HM/UHM) carbon fiber reinforcement.

A rotor for a motor comprising a frame having a hub for connecting the rotor to a shaft and a perimeter portion for interacting with a stator of the motor to cause the rotor to rotate about an axis of rotation. The frame comprises legs extending from an outer portion of the frame towards the hub, each leg having an inner end at the hub and an outer end at the outer portion of the frame, the inner ends of a first plurality of legs being spaced from the inner ends of a second plurality of legs in a direction along the axis of rotation.
