Latest Patents

One of his latest patents is a sensor device for high-speed rotating machines. This device includes a rotating body and a sensor assembly. The rotating body features a magnetic permeable ring and at least one positioning structure. The magnetic permeable ring contains a radial displacement sensing area and a rotational speed sensing area, with the positioning feature arranged in the rotational speed sensing area. The sensor assembly comprises four radial displacement sensors and two rotational speed sensors. The radial displacement sensor is a double-probe type, while the speed sensor can be either a double-probe or four-probe type sensor. This innovative design allows for the calculation of the rotation speed and turning direction of the rotating body.

Another significant patent by Chen is a rotor driving system and method for driving a rotor. This system includes a rotor, a revolution sensor, a sensing circuit, a controller, and a rotor driver. The revolution sensor is designed to sense the revolution frequency of the rotor, generating a measurement signal. The sensing circuit is connected to the revolution sensor and converts the measurement signal into a current revolution measured value. The controller, also connected to the sensing circuit, generates an estimated revolution frequency based on historical and current measured values, along with a reference value. It then produces a rotor driving signal based on this estimated frequency and a revolution control signal. The rotor driver is responsible for driving the rotor to rotate according to the generated signal.
