A 36 volt electrical system ( operating at 42-45 Volts ) is used to operate a permanent magnet motor / generator unit mounted to the engine in a similar fashion to a conventional alternator.

A special automatic transmission ( designated as a 2ML70 by General Motors ) incorporates two 82 kW ( 110 hp peak ) three phase permanent magnet motors, three planetary gear sets, and four selectively engaging friction clutches.

Your model and photograph would be fine illustrating " a simple DIY DC permanent magnet motor " ( demonstrating that it is not necessary to reverse the current flow, but only to switch it of for 180?).

This two facts, in addition to the cheaper price of a permanent magnet motor with respect to a standard DC motor ( as a matter of fact only the rotor coils need to be winded ), are the main reasons why armature controlled motors are widely used.

Many types of permanent magnet motor cannot be disassembled without ruining the magnet . ( When the motor is assembled, other parts of the motor short out the magnetic field . ) This is also the reason why permanent magnets are sometimes stored with an iron " keeper " across the poles.

:: : : : 87.102.86.73 points out below, that then starts to beg the question of which motors are " AC " motors and which are " DC " motors . ( I also suspect ( but have no proof ) that a modern permanent magnet motor is lighter than an induction motor for a given mechanical power .)

Oceanvolt has received several awards for its SD8.6 saildrive system, the latest being the 2013 Pittman Innovation Award given by SAIL Magazine for Oceanvolt's " compact robust design " featuring waterproof permanent magnet motor with closed circulation liquid cooling, single lever control with motor status shown by LEDs, and folding propeller which doubles as a hydrogenerator, silently extracting several kilowatts of electric power from the boat's forward motion while under sail.
