A Direct Curent motor or DC motor is a type of electric motor that converts electrical energy into mechanical energy using direct current. DC motor is used in a wide range of applications to power a variety of appliances and tools. The speed of DC motors can be controlled by varying the supply voltage with a frequency or speed converter. The most common voltages are 12 V and 24 V.
A brushless motor is a self-piloting electric motor that uses a rotor made up of one or more permanent magnets. The brushless motor uses direct current, but contains no rotating commutator. This makes them highly efficient and more resistant to wear.
An asynchronous motor, or induction motor, is a type of alternating current (AC) electric motor where the rotor is not in phase with the rotating magnetic field of the stator. This means that the rotor speed is always slightly lower than the speed of the rotating magnetic field, hence the term “asynchronous”. Asynchronous motors can be single-phase or three-phase.
A geared motor or motoreducer is a mechanical device that combines an electric motor with a speed reducer in a single compact unit. The main purpose of a geared motor is to reduce the high rotational speed of the motor to a lower, usable speed while increasing torque. This allows precise and efficient control of motion in a variety of applications.
A servomotor is an electromechanical device used to provide precise control of angular position, speed and acceleration. The servomotor is widely used in applications requiring high-precision controlled motion, such as robotics, industrial automation and control systems.
A high torque reducer is a mechanical device designed to reduce the speed of rotation while increasing the output torque of a motor. This reducer is specifically designed to provide a high torque output, which is essential for applications requiring considerable rotational force to move or handle heavy loads.
An alternator is an electromechanical device that converts mechanical energy into electrical energy in the form of alternating current (AC). The alternator is widely used in a variety of applications, including vehicles, power plants and portable generators.
A linear actuator is a mechanical device that converts electrical, hydraulic or pneumatic energy into linear motion, i.e. straight-line movement rather than rotation. Linear actuators are used for a variety of applications where precise, controlled movement in a specific direction is required.
A rotary actuator is a mechanical device that converts electrical, hydraulic, pneumatic or other energy into rotary motion. The rotary actuator is used in applications where angular or rotational movement is required, to control devices such as valves, robotic arms and handling equipment.
Motor control electronics, also known as motor controllers or variable speed drives, are a set of electronic devices and circuits used to control the operation of an electric motor. These electronics are used to manage various motor characteristics, such as speed, torque, direction and position, according to the needs of the application.
A standby or emergency battery is a secondary energy source used to maintain power to critical systems in the event of a main power failure. It ensures the continued operation of electrical and electronic devices when the main power supply is interrupted. Standby batteries are commonly used in computer systems, security devices, telecommunications and other applications requiring uninterrupted power.
A stepper motor is an electric motor that converts electrical impulses into angular movements. Unlike DC motors or asynchronous motors, which rotate continuously, a stepper motor moves in distinct ‘steps’. Each step corresponds to a precise rotation of the motor, allowing very precise control of position, speed and acceleration.
A motor pump submersible is an electric motor designed to operate when fully submerged in a liquid, usually water. These electric submersible motors are incorporated into submersible pumps, which are used to pump liquids in various industrial applications.
A linear cylinder actuator is a mechanical device that converts rotation into linear motion, enabling objects to be moved or manipulated in a straight line. Linear cylinders are used in a wide range of industrial applications.
A torque motor, also known as a high torque motor or direct torque motor, is an electric motor designed to produce high torque at low speeds, often without the need for a reduction gear or intermediate gears. These motors are capable of delivering high rotary force directly from their output shaft, making them suitable for applications requiring high precision and direct control of motion.
An electromagnet produces a magnetic field when supplied with an electric current. The electromagnet converts electrical energy into magnetic energy. The electromagnet consists of a winding and a pole piece of soft ferromagnetic material called the magnetic core, which channels the magnetic field lines.
An electromagnetic damper is a motion control device that uses electromagnetic forces to absorb and dissipate kinetic energy, typically to reduce vibration and shock in various mechanical systems. Unlike traditional mechanical dampers that use viscoelastic materials, springs or fluids to absorb energy, electromagnetic dampers use magnetic fields generated by electrical currents.
Among position sensors, a resolver is an extremely reliable and accurate electromechanical angular position sensor, widely used in demanding environments where robustness is crucial. The RVDT (Rotary Variable Differential Transformer) sensor is a rotary position sensor that accurately measures the angle of rotation.
