Abstract
¡¡¡¡¡¡
The angular acceleration of a rotary shaft is one o f the most important parameters for revolution mechanism, which is widely employed in practical applications .The principles and approaches for measuring angular acceleration were studied to find a feasible way to obtain the accurate and successive value of angular acceleration .A new method to measure the mechanical angular acceleration of rotating system is established by changing the exciting mode of AC asynchronous tacho-generator, and form a angular acceleration tacho-generator to measure the mechanical angular acceleration directly. This method can reflect the changes of mechanical angular acceleration in various rotating system, and it is suitable for the fields where the mechanical angular acceleration changes so quickly. Experimental results generated from testing of mechanical angular acceleration caused by rotating magnetic field when the induction motor is operating without any load are truly feasible.
¡¡¡¡¡¡
I graduated from the Design of the issue is control of the intelligent use of SOC speed measuring instrument. The system is the motor angular acceleration measurement, and PC and can communicate that the motor angular acceleration, and to observe the motor running the basic situation.
