As an introduction we will briefly comment on what each of these devices is:
Electric motor
An electric motor is a device that converts electrical energy into mechanical energy, producing movement. It works through the interaction between magnetic fields generated by electric current and moving components within the motor. Electric motors are widely used in a variety of applications, from household appliances to industrial machinery and transportation.
Basically, an electric motor consists of two main parts: the stator and the rotor. The stator is the fixed part of the motor and contains coils of wire wound around an iron core. These coils are passed through by electric current, creating a stationary magnetic field. The rotor is the moving part of the motor and usually consists of a shaft that rotates inside the stator. The rotor also contains coils of wire and is connected to a set of permanent magnets or has an electromagnetic design that interacts with the magnetic field created by the stator.
When electric current is applied to the stator, a stationary magnetic field is generated. This field interacts with the magnetic field generated by the rotor, causing the rotor to rotate and produce mechanical motion. The direction and speed of movement depend on the direction and intensity of the applied electric current.
Electric motors are classified into different types according to their design and application, such as direct current (DC) motors, alternating current (AC) motors, stepper motors, among others. Each type of motor has specific characteristics that make them suitable for different applications.
In short, an electric motor is a device that converts electrical energy into mechanical movement through the interaction of magnetic fields generated by electric current. It is a fundamental technology in a wide range of industrial, commercial and consumer applications.
We have classified electric motors on our website based on their size.
Electric Linear Actuator
An electric linear actuator is a device that converts electrical energy into linear motion, allowing rectilinear movement along a path. These devices are widely used to control and automate a variety of mechanisms, systems and processes where controlled linear motion is required.
Electric linear actuators are usually composed of several main components. First of all, there is the electric motor, which can be of different types such as direct current (DC) motors, stepper motors or alternating current (AC) motors. This motor converts electrical energy into rotational mechanical energy.
In addition to the motor, there is a transmission mechanism that is connected to the electric motor and is responsible for transforming rotary movement into linear movement. This can be accomplished by using screws, spindles, belts, or rack and pinion systems.
The linear structure is the part of the actuator that moves linearly and is connected to the transmission mechanism. It may be a bar, rod, or other component designed to provide rectilinear movement.
Some linear actuators may also include feedback devices, such as encoders or position sensors, that provide information about the current position of the actuator. This is especially useful for applications requiring precise position control.
Electric linear actuators are used in a wide range of industries, including automotive, robotics, manufacturing, medical industries, among others. They offer advantages such as precise control, ease of automation and the ability to integrate with electronic systems for more sophisticated control. Their versatility and ability to provide linear motion make them a popular choice in many industrial and commercial applications.
Gearmotor
A geared motor is a type of motor that is equipped with an integrated speed reduction mechanism, known as a reducer or gearbox. This mechanism reduces the rotational speed of the motor output, while increasing the torque applied.
The reducer is made up of gears of different sizes that interact with each other to modify the speed and torque of the motor output shaft. Generally, this type of motor is used when high torque is required at lower rotational speeds.
Geared motors are used in a wide variety of applications where motion control is needed, such as in transportation systems (such as electric vehicles, cranes, and robots), in industrial automation systems (such as conveyor belts, automatic doors, and production machinery), and in domestic applications (such as household appliances and toys).
In summary, a geared motor serves to provide high torque at low rotation speeds, making it useful in applications where controlled and powerful movement is required.
Servo or servomotor
A servomotor is a type of electric motor used to control movement precisely. It differs from other motors in its ability to maintain a specific position or to rotate at a specific speed and angle. This is achieved thanks to a feedback system that allows the servomotor controller to continuously adjust the position of the axis based on the input signal.
Servomotors consist of three main parts:
- Motor: Similar to other electric motors, the servo motor has a motor that generates the movement. This motor can be direct current (DC) or alternating current (AC), depending on the specific application.
- Gearbox: Many servomotors are equipped with a gearbox that reduces motor speed and increases torque, allowing for more precise control of movement.
- Feedback system: This is a crucial feature that distinguishes servo motors. They use feedback devices, such as encoders or potentiometers, to measure the position or speed of the shaft and send this information back to the controller. The controller uses this feedback to adjust the input signal and precisely control the position or speed of the servomotor.
Servomotors are used in a wide variety of applications that require precise control of motion, such as robotics, positioning systems, flight control systems in airplanes and drones, CNC (Computer Numerical Control) machines, 3D printers, and many other industrial applications. and commercial.
In summary, a servomotor is a type of electric motor that is characterized by its ability to precisely control position, speed and angle of rotation, thanks to a feedback system that allows continuous adjustments in response to an input signal.
Stepper motor
A stepper motor is a special type of electric motor that converts electrical pulses into discrete, precise movements of the output shaft. It is called "stepping" because it advances in small steps or angular increments in response to the electrical pulses it receives. Each pulse moves the motor forward a fixed angle, called a step, allowing precise control over the position and movement of the motor.
Stepper motors are made up of a rotor and a set of electromagnetic coils arranged in the stator. The rotor usually has magnetic teeth or poles that interact with the magnetic fields generated by the stator coils. Depending on the specific motor design, the stator windings can be excited in different ways to induce stepping movements.
There are various types of stepper motors, such as unipolar and bipolar stepper motor, as well as different winding configurations, such as single, dual or multi-phase motor. Each type and configuration has its own specific characteristics and applications.
Stepper motors are used in a wide range of applications that require precise control of motion, such as 3D printers, CNC (Computer Numerical Control) machines, positioning systems, robotics, industrial automation systems, camera focusing systems, and more. They are especially useful when exact control of position, speed and direction of movement is needed.
In short, a stepper motor is a special type of electric motor that converts electrical pulses into discrete, precise movements, advancing in small angular steps in response to these pulses. It is widely used in applications that require precise control of movement.
Motor pumps
Motor pumps, whether for air or water, are devices designed to transport fluids from one place to another. In the case of water pumps, they combine a motor and a pump in a single unit to move liquids, such as clean water, dirty water or chemicals, from an entry point to an exit point. These motor pumps are essential in a variety of applications, such as agricultural irrigation, drinking water supply, stormwater drainage and wastewater pumping.
On the other hand, air pumps, also known as air compressors, perform a similar function, but instead of moving liquids, they compress air from an entry point to an exit point. These air compressors are essential in various industrial, commercial and home applications, such as air tools, paint and finishing systems, tire inflation, air conditioning and refrigeration systems, and industrial operations.
Both types of motor pumps can be driven by internal combustion engines, such as gasoline or diesel engines, or by electric motors, depending on the application and the specific needs of the user. In short, whether for water or air, motor pumps play a crucial role in a wide range of applications where the efficient movement of fluids or the generation of compressed air is required.
