Motors are essential components of all electrical devices. They are used in machines and robots, allowing them to perform specific work and actions, move and respond to user commands. An electric motor converts electrical energy into mechanical energy, so that a specific reaction and action takes place. We can distinguish between a DC electric motor and an AC electric motor. In addition, there is another division which includes a vibrating, commutator, vibrating and brushless motor. There is also a tunnel drive, which can be used to create a model of a fake jet. Electric motors have found their application in vehicles, household appliances, building automation systems, robots, production plants, factories and warehouses, wherever human duties are taken over by machines. In Botland's offer you will find a wide range of simple and more advanced engines, whose voltage is 12V or 24V. So adjust both type and voltage to the design requirements of your robot.

Commutator and BLDC motors
If you are looking for the simplest DC motor, a commutator motor is the best choice. It contains a commutator consisting of copper plates, which is an element of the rotor and is responsible for feeding the voltage to the rotor circuit. The operation of the motor is based on the magnetic field produced, which interacts with the magnetic field of a stationary stator. The commutator motor has a very simple design. It allows to control the rotational speed. It is used in household appliances and in robots and automation systems. There are commutator motors with gearbox, direct drive and slow speed motor.
An innovative alternative to the commutator motor is the BLDC motor. It does not transfer power to the rotor via brushes. The rotor is made up of permanent magnets, it is built by a stator, and at other times it rotates inside the stator. As for the voltage polarity change, it occurs via a static commutator, based on transistors. Brushless DC motors are worth noting, which are characterized by a very long life, high efficiency and low energy consumption. At the same time they are smaller than commutator models. They are used in fans and air conditioners, sometimes also in RTV equipment and electric vehicles.
Specifications of stepper and vibration motors
An interesting type of brushless motor is the stepper motor, in which the rotor does not rotate in a continuous system and is supplied with a voltage characterized by a pulse pattern. A single pulse initiates the rotation of the rotor. The size of the stepper resolution determines the angle of rotation of the rotor, the larger it is, the smaller the angle. Stepper motors work very well in CNC machines. They are used in vehicle components, but also in printing machines. They are also a solution for robotics projects.
One of the electric motors is the vibration motor, which has an asymmetrical load on the shaft. This results in a proportional centrifugal force, which puts the motor into vibration. Such a solution is found in game consoles and also works very well in mobile phones. The vibration motors also power the massage machines. They are therefore very multifunctional.
Our Botland store offers motors with less and more advanced parameters and a specific purpose. These include simple commutator motors and advanced BLDC motors. We also recommend vibrating and stepper motors. Choose the engine which parameters best suit your design goals and assumptions. Pay attention to the voltage and working conditions, as well as the way of operation that determines the effectiveness of the robot's actions.
