Concentric circular heavy hammer electrode is a sensor used in electric motors and generators, mainly for measuring the rotational speed and position of the rotor. The key principles are as follows:
Structural features:
Composed of two concentric metal rings, with a certain gap between the inner and outer rings.
The outer ring is generally grounded as a capacitor, while the inner ring is connected to the rotor through insulating material.
working principle:
When the rotor rotates, the inner ring also rotates, and due to the gap between the inner and outer rings, the charge on the inner ring changes as it rotates.
This change causes the capacitance value between the inner and outer rings to vary with the position of the rotor.
Capacitance variation:
When the rotor rotates, the charge distribution on the inner ring is uneven, causing the capacitance value between the inner and outer rings to change with the rotation angle.
This change in capacitance value can be detected and measured through circuits.
Signal processing:
By using signal processing circuits, the changes in capacitive sensors are converted into voltage or frequency signals.
These signals can be used to determine the rotational speed, angle, or position information of the rotor.
Application:
In electric motors and generators, concentric circular hammer electrodes are commonly used for rotor position detection and speed measurement.
Real time monitoring of the operating status of the rotor can ensure the safe operation and precise control of the equipment.
Overall, the concentric circle heavy hammer electrode utilizes the capacitance changes between the inner and outer rings to detect the motion state of the rotor, making it an accurate and reliable speed and position sensor.
