Commutator motor MT78 - principle of operation
Electricmotor MT78 is a miniature DC commutator machine. In this motor, the voltage from the power source is applied to the commutator parcels connected to the rotor windings. As a result of current flowing through the rotor windings, a magnetic field is generated which interacts with the stator magnetic field created by the permanent magnets without windings. The commutator is the element responsible for changing the polarity of the voltage, which causes the rotor to spin consistently in the same direction.

Application examples for MT78 motor
In addition to its low price, the MT78 motor offers numerous practical advantages. Small dimensions, low weight, high efficiency and very good build quality allow this motor to be used in numerous applications. This miniature commutator motor can be used in miniature mock-ups showing prototypes of electro-mechanical systems driving equipment operating in open pit lignite mines. Also a popular application for such motors as MT78, are all remote-controlled toys and robots.
