Electric motor with Hall sensor brand Weikewei

Release: Weikewei Technology

Generally speaking, the mainstream nowadaysMotor with Hall sensorThe use of can expand the range of communication instruments,The motor with Hall sensor is made according to the principle of transformer, and it has a certain current ratio. As electricity users, we need to choose according to the amount of electricity used. If it is a major electricity consumer, such as factories, mines, and enterprises, it is necessary100AThe current we currently use, both single-phase and three-phase meters, cannot accommodate such a large current. Therefore, we need to choose a current transformer to proportionally convert the large current into a small current, and then measure it with a low range instrument. This is equivalent to expanding the range of the AC meter. The application of parallel resistors includes digital ammeters. This is a more cost-effective method than Hall effect sensors. Parallel resistors can also provide a low resistance path and allow current to pass from one point in the circuit to another.

Secondly, we knowMotor with Hall sensorIt can isolate high currents and improve user safety,We use a motor and Hall sensor to convert high current into low current. From the structure of the current transformer, we can see that there is no direct electrical connection between its primary and secondary sides. They are only coupled by a magnetic circuit. When measuring high current, the primary side of the current transformer is directly connected to the measurement circuit, while the secondary side is connected to the AC instrument, which has no direct electrical relationship with the measured circuit. In this way, the measured AC instrument and operator are separated from the high-voltage electricity, thus protecting personal safety and instrument safety.

The use of motors and Hall sensors can reduce production costs and standardize the production of instrumentsThe third function of current transformers is to promote standardization in instrument production. We know that the current on the secondary side of current transformers is uniformly made into a standard5ATherefore, as long as the production range is5AJust use an AC ammeter, and then equip different current transformers according to different current levels. This not only reduces production costs but also standardizes instruments, killing two birds with one stone, which is very good.
