   Makers of miniature working steam engines (i.e. "live steam") to be used as educational toys. Note that some of these companies no longer produce toy steam engines today. Wikimedia Commons has media related to Model steam engine manufacturers .

3. DC motor - Wikipedia

   en.wikipedia.org/wiki/DC_motor

   A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.

4. Fractional-horsepower motor - Wikipedia

   en.wikipedia.org/wiki/Fractional-horsepower_motor

   Servo motors and stepper motors are specialist types of fractional-horsepower electric motors usually intended for high-precision or robotics applications. Usually running from a DC supply, when combined with a planetary gearbox can offer accuracies less than 8 arc-minutes (2 ⁄ 15 ths of a degree, or approx. 2.3 milliradians). Due to their ...

   Weeden Vertical toy steam engine in the 1912 Sears, Roebuck and Co. catalog. In the late 19th century, manufacturers such as German toy company Bing introduced the two main types of model/toy steam engines, namely stationary engines with accessories that were supposed to mimic a 19th-century factory, [4] and mobile engines such as steam locomotives and boats.

6. Brushless DC electric motor - Wikipedia

   en.wikipedia.org/wiki/Brushless_DC_electric_motor

   A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.

7. Electric motor - Wikipedia

   A miniature coreless motor. The coreless or ironless DC motor is a specialized permanent magnet DC motor. [74] Optimized for rapid acceleration, the rotor is constructed without an iron core. The rotor can take the form of a winding-filled cylinder, or a self-supporting structure comprising only wire and bonding material.
