MT78 commutator motor - operating principle
The MT78 electric motor is a miniature DC commutator machine. In this motor, voltage from the power supply is fed to the commutator plots connected to the rotor windings. As a result of the current flowing through the rotor windings, a magnetic field is produced which interacts with the stator's magnetic field, which is formed by the permanent magnets without winding. The commutator is the element responsible for changing the voltage polarity, which causes the rotor to rotate invariably in the same direction.
Application examples for the MT78 motor
In addition to its low price, the MT78 engine also offers numerous practical advantages. Its small dimensions, low weight, high efficiency and very good workmanship make it possible to use this motor in numerous applications. This miniature commutator motor can be used in miniature mock-ups showing prototypes of electromechanical systems driving the mining equipment operating in opencast lignite mines. Also a popular application of engines such as MT78 are all toys and remote control robots.
