Cuff Pump parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Stator Assembly 3 parts 1× Stationary part of an electric motor: a slotted laminated core wound with copper coils that produce the rotating magnetic field.
2 Rotor Assembly 4 parts 1× Rotating member of an electric motor: a laminated steel core carrying permanent magnets or conductor bars, pressed onto a shaft that delivers the torque.
3 Pump Diaphragm 1× Flexing diaphragm and check valves that move air into the cuff each motor revolution.
4 Motor Housing 1× Cast or extruded aluminium shell that carries the stator, locates the bearings, and conducts heat away from an electric motor.
