MBS electrical components Germany MBS model MBS price

MBS electrical components are devices that convert electrical energy into mechanical energy. They utilize energized coils (i.e., stator windings) to generate a rotating magnetic field that acts on the rotor (such as a squirrel-cage closed aluminum frame) to form electromagnetic rotational torque. Electric motors are classified into DC motors and AC motors based on the power supply used. Most motors in power systems are AC motors, which can be synchronous motors or asynchronous motors (where the speed of the stator magnetic field does not remain synchronized with the rotor rotation speed). An electric motor mainly consists of a stator and a rotor. The direction of motion of current-carrying conductors under force in a magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field direction). The working principle of an electric motor is that the magnetic field exerts force on the current, causing the motor to rotate.

MBS electrical component characteristics

Under normal circumstances, the actual static characteristic output of a sensor is a curve rather than a straight line. In practical applications, to enable instruments to have uniformly scaled readings, a fitted straight line is often used to approximately represent the actual characteristic curve. Linearity (non-linear error) is a performance indicator of this degree of approximation. There are various methods for selecting the fitted straight line. For example, the theoretical straight line connecting the zero input and full-scale output points can be used as the fitted straight line; or the theoretical straight line that minimizes the sum of squared deviations from each point on the characteristic curve can be used as the fitted straight line, known as the least squares fitted straight line.

MBS electrical component composition

A two-terminal electronic component made of resistive material, with a specific structural form, capable of limiting current flow in a circuit. Those with unchangeable resistance values are called fixed resistors. Those with variable resistance values are called potentiometers or variable resistors. An ideal resistor is linear, meaning the instantaneous current through the resistor is directly proportional to the applied instantaneous voltage. Some special resistors, such as thermistors, varistors, and sensitive elements, have a non-linear relationship between voltage and current. Resistors are the most numerous components used in electronic circuits, typically forming different series based on power and resistance values for selection by circuit designers. In circuits, resistors are mainly used to adjust and stabilize current and voltage, serving as shunts and voltage dividers, and also as circuit matching loads. Depending on circuit requirements, they can also be used for negative or positive feedback in amplifier circuits, voltage-to-current conversion, voltage or current protection during input overload, and can form RC circuits to serve as oscillation, filtering, bypass, differentiation, integration, and time constant elements.

MBS electrical component classification

Microphones can be classified into dynamic microphones and condenser microphones based on their transduction principle. Dynamic types can be further subdivided into moving-coil microphones and ribbon microphones. Common commercial microphone types include condenser microphones, crystal microphones, carbon microphones, and dynamic microphones. Commonly used condenser microphones utilize two types of energy sources: DC bias power supplies and electret films. Both these types of condenser microphones and crystal microphones convert acoustic energy into electrical energy, generating a changing electric field. Carbon microphones use a DC voltage source, changing their resistance through sound vibration, thereby converting acoustic signals into electrical signals. Condenser, crystal, and carbon microphones all generate a voltage signal proportional to the displacement of the sensitive diaphragm, while dynamic microphones generate a voltage signal proportional to the vibration velocity of the sensitive diaphragm. Dynamic microphones use permanent magnets as an energy source, converting acoustic energy into electrical energy based on electromagnetic induction.
