Instantaneous rotation speed measurement system based on variable reluctance sensors: Model and analysis of performance

There are few reports on high rotational speed measurement of brushless direct current (DC) motors based on giant magneto-inductive effect. In this study, a rotational speed measurement system based on giant magneto-inductive effect is established for measuring the rotational speeds of DC motors. Successive sawtooth waves are found when rotating shaft is close to the GMI sensor. Through using the magneto-inductive sensing system, different high rotational speeds (1500∼24000 r/min) of the motor are accurately measured. Therefore, this giant magneto-inductive sensor may be used for high rotational speed measurement of motors.

Speed Measurement

Instantaneous speed measurement system can accurately measure the rotating target and realize the rotation direction judgment. It plays a very important role in industrial applications, as monitoring or controlling the rotation speed of transmitter, motor, turbine. With the development of technology, a modern speed measurement system is demanded to be intelligent, high integration, high precision, high reliability, and low cost etc. Based on the large number of literatures, this paper is a comprehensive review of the principle and application of domestic and foreign mature technology of rotation speed measurement method at present. Through the systematic classification, relationship between the different speed measurements is revealed, and the advantages and disadvantages of different measuring sensor are presented, so that readers can choose reasonable speed measurement method depending on the application, the actual measurement requirements and the test purposes.

Optic Communication

AlGaAs/GaAs heterojunction bipolar transistor (HBT) high speed ICs have been paving the way for the most sophisticated fiber-optic communication systems since the late 1980s. Recently 20 Gbps HBT ICs have been developed to accommodate the emergence of optical fiber amplifiers. HBT technology is now proceeding towards the development of 40 Gbps systems where the lack of high speed measurement system remains an issue.
