Direct current motors (DC motors) convert electrical energy into the rotary motion of the shaft. Unlike servo drives, these motors do not keep information about the current position of the shaft. However, this does not change the fact that they are still widely used due to their simple structure and low costs. TME offers a wide range of DC motors that can be successfully used both in large industrial projects and in the backyard labs of electronics enthusiasts.
In addition to the aforementioned servo drives, there are three most common groups of DC motors:
Ferrite core brush-type motors – the most common and simplest type of electric drives. They consist of a ferrite core around which the winding is wound; brushes fed with direct current; winding switching commutator; the stator with permanent magnets and the rotor, i.e. a moving element. Their disadvantage is the relatively quick wear of the brushes and their susceptibility to unfavorable environmental conditions.
Brush-type coreless motors – unlike the first group, these drives do not have a core. Instead, the rotor is set in motion; it consists of a winding which in this case is outside the permanent magnets located in the motor housing.
Brushless motors – in their case, the mechanical commutator is replaced by an electronic one. This type of an electric motor is characterized by its higher reliability – the lack of contact between the brushes and the commutator means that only the bearings suffer from mechanical wear. However, due to the need for more complex control systems, their cost is higher than in the case of brushed motors.
TME's offers DC motors that can be used in both simple applications and more complex systems. The TME’s catalogue includes the simplest drives that will be used to move a wirelessly controlled car, as well as more advanced motors, e.g. with an integrated encoder, designed for larger-scale projects.
