DC Thruster 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 Thruster Propeller 1× Nickel-aluminium-bronze ducted propeller matched to the motor torque curve.
4 Thruster Duct 1× Kort-style nozzle that raises static thrust at low speed.
5 Oil Compensator 1× Flexible bladder that fills the motor with oil and equalises internal to ambient pressure.
6 Ball Bearing 2× Deep-groove radial ball bearing.
7 Oil Seal 2× Spring-loaded rotary lip seal that keeps lubricant inside a housing and dirt out where a shaft passes through, sized to DIN 3760.
