    Three Phase Induction Motor Working Principle

    How does an 3-phase induction motor work?In short, it works based on the principle of electromagnetic induction. When the stator windings are supplied with three-phase alternating current, a rotating magnetic field is generated between the stator and the rotor. The rotating magnetic field cuts the rotor windings to generate induced electromotive force and current in the rotor circuit. The current in the rotor conductor forces the rotor to rotate under the effect of the rotating magnetic field. Below, let’s specifically analyze the generation of rotating magnetic field, its direction and speed as well as slip.

    How Does a Transformer work?

    How does a transformer work? Transformers mainly applies electromagnetic induction principle to work, the working principle details are as follows: When the primary side of the transformer is applied with the alternating voltage U1 and the current flowing through the primary winding is I1, then the current will generate alternating magnetic flux in the iron core to generate electromagnetic connections between the primary winding and the secondary windings.

    Magnetostrictive sensor working principle

    Magnetostrictive sensor indicates a kind of displacement detecting device developed based on ferromagnetic material magnetostrictive effect. It could be used for continuously, precisely and real-time detecting the displacement (position) and velocity of various moving parts under abominably industrial environment. As an important component to realize precise operation and control, it can substantially enhance the precision and efficiency of the whole system. It is applicable for detecting the stroke or position of mechanical device with rectilinear motion. Precision servo feedback control of hydraulic system is one of the most typical applications.

    Electromagnetic Relay Working Principle & Testing

    How does an electromagnetic relay work? Electromagnetic relay uses electromagnet to control “on” or “off” status of the operating circuit. Electromagnetic relay consists of electromagnet, armature, spring, movable contact and stationary contact. When placing voltage to both ends of a coil, the coil will be flowed with current and generate electromagnetic effect.

    Planetary Speed Reducer Working Principle and Applications

    The planetary speed reducer or gearbox is a kind of transmission mechanism. It utilizes the speed transducer of the gearbox to reduce the turnover number of the motor to the required one and obtain a big torque. How does a planetary gearbox work? We can learn more about it from the structure. The main transmission structure of the planetary gearbox is planet gears, sun gear and ring gear.

    Brushless DC Motor, How it works?

    Brushless DC motor consists of the motor and drive, is a typical mechatronic product. The stator windings of the motor are mostly made using three-phase symmetrical star connection, which is very similar to the three-phase asynchronous motor. Magnetically charged permanent magnets are attached to the rotor of the motor. In order to detect the polarity of the motor rotor, a position sensor is provided in the motor.

    Power Line Filter Basics & Working Principle

    What is a power line filter? What does a power line filter do? A power line filter, also called EMI power line filter, is a passive bi-directional network, electrical equipment which effectively filters the particular frequency point in the power line or the frequency out of the particular frequency point. Power line filter is to get a certain frequency power supply signal or the power supply signal after eliminating a certain frequency through connecting power supply filter in power line...

    Solid State Relay Basics & Working Principle

    What is a solid state relay(SSR)? A solid state relay is a non-contact switch fully composed of solid state electrical-element, which can drive high-current load with a small control signal. It can achieve switching on and off with no contact and no spark due to the switching characteristics of electrical element (i.e. semiconductor components like switch transistor, triac and so on). Solid state relay has such following advantages over electromagnetic relays: high reliability, no contact, no spark, long life, fast switching speed, strong anti-interference ability, and small size.

    Servo Motor Basics & Working Principle

    What is a servo motor? Servo motor is the motor which controls mechanical components operation in servo system. Servo motor can convert voltage signal to torque and speed, then to drive the control object. The control speed and position accuracy is very high. In auto control system, servo motor can response rapidly as executing component, convert the receiving electrical signal to angular displacement or angular velocity output of motor axis. The main feature is, when signal voltage is zero and no self-rotation, rotation speed will descend at even speed along with the torque increasing. Servo motor has 2 types, DC servo motor and AC servo motor.

    Servo Drive Basics & Working Principle

    The servo drive is a kind of controller to control the servo system. Its function is similar to the frequency effect on ordinary AC motor, which belongs to a part of the servo system and is mainly applied in high-accuracy positioning system. Generally, the servo motor is controlled by three ways, location, speed and torque, so as to realize high precision positioning of transmission system.

    Stepper Motor Basics & Working Principle

    Stepper motor is an actuator transforming electric pulse into angular displacement. Popularly, when receiving a pulse signal, the stepper motor will rotate a fixed angle (namely"stepping angle") according to the direction set for the stepper motor. The angular displacement volume can be controlled by controlling the pulse number to achieve the purpose of positioning accurately. In the meantime, the rotational velocity and acceleration of motor can be controlled by controlling the pulse frequency to achieve the purpose of speed control.
