DC generator working principle
The working principle of the DC generator is to change the alternating electromotive force induced in the armature coil. The DC motor is based on the commutation function of the commutator and the brush to change the DC electromotive force when it is taken out from the brush end.
The direction of the induced electromotive force is determined according to the right-hand rule (the magnetic line is pointing to the palm of the hand, the thumb is pointing to the direction of movement of the conductor, and the other four fingers are pointing in the direction of the induced electromotive force in the conductor).
How does a DC motor work?
The direction of the conductor's force is determined by the left-hand rule. This pair of electromagnetic forces forms a moment acting on the armature. This torque is called electromagnetic torque in the rotating machine. The direction of the torque is counterclockwise, in an attempt to rotate the armature counterclockwise. If this electromagnetic torque can overcome the resistive torque on the armature (such as the resistive torque caused by friction and other load torque), the armature can be rotated counterclockwise.
Gamicos, aims to provide customers more options when they want to buy a product to measure object's pressure. Differential Pressure Sensor, also called differential transmitter or differential transducer, is used to measure the difference between two pressures, It can be used to measure the differential pressure of different medium like water, air, oil, gas, etc. The working principle of the differential pressure sensor is that the measured pressure directly acts on the diaphragm of the sensor, so that the diaphragm produces a small displacement proportional to the water pressure, so that the resistance value of the sensor changes, and the electronic circuit is used to detect this change, and convert the output of a standard measurement signal corresponding to the pressure.
