DC motors (Gleichstrommotoren), such as models GR30, GR42 and GR53 are used in most electronic devices and household applications. It is widely used in CD players, computers, remote control airplanes, electric razors and so on. It is considered to be the most straightforward types of motor used in many of the electrical appliances. In comparison with the AC motor, it is strong and more controllable.

Working procedure of DC motors
An armature is set between the north and south poles of the magnet inside the motor. The magnetic field interacts with the field created by the armature when electricity is passed throughout the armature. The polarity that is opposite causes the motor to turn.There are essentially three kinds of DC motors such as the stepper motor, the brushed and the brushless motors (bürstenloseGleichstrommotoren).
 Stepper motors: Some of the most common varieties of Direct Current motors include the stepper motor. These electrical brushless motors function on the basis of electromagnets that rotate the rotating shaft that is internal. There are computer controlled stepper motors for sale in most of the on-line and offline shops. It is popular in CD drives, floppy drives, satellites, toys and scanners. Because of its procedures that were practical, it can be controlled fairly easily. As it comprises low electricity but the stepper motors require an outside controller.
 Brushed Motor: The Brushed motors are regarded as the normal dc motors that can be powered by almost any Direct Current battery. It comprises a split run commutator. Both the ring and the brushes will need continuous replacements. The modern brushes are made of carbon which will be durable in comparison to the copper wires. Additionally, it causes less friction. These devices are easy to control and less expensive.
 Brushless Motors: It is considered to be the most suitable device as these motors do not comprise of brushes. It is permanent and includes maintenance that is less. Additionally it is powerful and efficient in comparison with the other types of
Direct Current motors.There is certainly hardly any possibility of friction and gear damage as this motor will not include brushes. It can consequently be used or heavy machineries and electric equipment. It really is also regarded as cost efficient and permanent.DC Planetary Gearmotorslike modelsIG22, IG32 and IG42or DC Spur Gearmotors (Stirnradgetriebemotoren)like RB30 and RB35 are utilized in different applications such as rehab equipment, ticketing machines, home automation, automotive, robotics, etc.Additionally in power tools, fans, toys, domestic appliances, etc. Their main advantage over AC Motors (Wechselstrommotoren) is the slimmer diameter, as well as the higher start torque.
