Claim 0:
1. A motor assembly for a catheter pump including a drive shaft and an elongate catheter body, the motor assembly comprising:
a motor comprising:
a motor housing;
a rotor and a stator disposed within the motor housing, the rotor configured to turn in response to a stator current conducted through the stator;
a drive magnet disposed within the motor housing and mechanically coupled to the rotor; and
a motor housing interface adjacent the drive magnet and comprising a securement device;

a driven magnet mechanically coupled to the drive shaft extending through the elongate catheter body; and
a flow diverter interface adjacent the driven magnet and configured to be coupled to a flow diverter having at least one fluid channel extending distally through the elongate catheter body, the flow diverter interface configured to engage the securement device to position the driven magnet relative to the drive magnet such that the driven magnet is electromagnetically coupled to the drive magnet.
