ST.LOUIS MOTOR

The St. Louis Motor is a robust and easy-to-operate demonstration model for studying the construction and working principle of a DC electric motor. The apparatus demonstrates the conversion of electrical energy into mechanical energy through the interaction between the magnetic field and the current-carrying armature.

The unit consists of a 2-pole DC armature fitted with coils, mounted on an aluminium bracket. The armature shaft is supported on brass cone bearings for smooth rotation and is fitted with a split commutator for proper current reversal during operation.

Two permanent magnets mounted in adjustable holders provide the magnetic field required for motor operation. Electrical connections are made through binding posts and 4 mm socket terminals. The complete assembly is mounted on a sturdy Bakelite base for stability during classroom demonstrations.
