DC motors - direct current

DC motors - DC Motors, electrical machines in which the electrical energy from the voltage source is converted into mechanical energy in a continuous rotational motion. The range of engines, direct drive , and in versions with manual transmission, straight, angular, and in versions with enkoderem, thinking about more complicated projects. The DC motor is the ideal way to enable Your project to progress.

How they are constructed and how they work DC motors?

The main design elements of a classic direct current motor, permanent magnets forming the stator and windings are connected with the package of copper sheetsthat form the rotor. The power rotor is fed through carbon brushes that have contact with komutatorem, consisting of the rotor plate. When the rotor winding is connected under tension, it is not flowing current that creates a magnetic field making you feel uncomfortable rotor into rotary motion as a result of interaction with the magnetic field of the stator. At the time when the rotor winding are parallel to the lines of force of the magnetic field of the stator, the commutator switches the polarity of the supply voltage, which leads to a reversal of the direction of the magnetic field in the rotor circuit, causing the contents of its rotation continuously in one direction. Thus, the direct current motor (DC) comes in movement and drives the movable elements.

Engines komutatorowe DC - simple design about many advantages

Simple design and stable technology for the production of commutator motors DC and their affordable price, led to the fact that these machines have become popular in many applications of a commercial nature, as hobbystycznym as a professional. DC motors can be powered by a constant voltage derived from a battery or AC adapter. The higher the voltage, the higher the rotational speed of the engine. We reversed the polarity of the battery or power supply will change the direction of rotation of the engine. If Your application requires adjustment of the engine speed, then you should definitely pick up the PWM driver, which allows smooth adjustment of the engine speed, in full. Advantages of DC motors, stands a high torque in the lower Rev range - even in a situation when the engine is under load, mechanically, will be able to quickly obtain the necessary speed of rotation.

What are the factors to consider when choosing a DC motor?

Picking up the engine for a specific project, you must consider its basic parameters nominal voltage, i.e. voltage, current consumption, torque and rotational speed. The value of the supply voltage determines the effect of the required torque at the corresponding speed. Statement too low voltage at the motor brushes will cause engine will not start, and the flow is too high voltage than the manufacturer recommends may cause the flow of too much current in the circuit of the rotor that was too strong impact elektrodynamiczne and heat, leading to irreversible damage of the rotor and even stator. Increasing the load on the motor shaft causes an increase in current consumption from the power source - in the case of engines operating with high load, it is necessary to use an additional radiator that increases the area of heat dissipation. The engine speed must be matched to the application requirements. The highest efficiency motors achieve higher speed. Adding gearing to reduce engine speed. Torque on the motor shaft or the driven mechanisms, is a value which directly affects the acceleration of the engine and its possible use in a particular application.
