1. A sequential propulsion drive assembly, configured to drive a mechanical system; the sequential propulsion drive assembly comprising:
a primary output shaft, extending through the motor housing through a forward bulkhead, a central bulkhead, and a rear bulkhead;
a collet, joined to a bottom plate and configured to stabilize the primary output shaft;
an upper primary shaft gear, operatively coupled to the primary output shaft and an upper output gear;
an upper electric motor, resting on the central bulkhead and further comprising an upper output shaft,
an upper clutch, joined to the upper output gear with the upper clutch;
a lower primary shaft gear, operatively coupled to the primary output shaft and a lower output gear;
a lower electric motor, resting on the rear bulkhead and further comprising a lower output shaft,
a lower clutch, joined to the lower output gear with the lower clutch;
a microcontroller, electrically coupled to the upper clutch and the lower clutch and programmed with a loop of instructions to execute while the sequential propulsion drive assembly is operative:
receiving an upper motor engagement instruction from a user or a controller;
engaging the upper motor to drive the upper output gear with the upper clutch;
receiving a lower motor engagement instruction from the user or the controller;
engaging the lower motor to drive the lower output gear with the lower clutch; and
iterating the loop of instructions;
wherein the upper motor and the lower motor turn the primary output shaft.
