The electric motor is one kind of the common device in in the daily life, Turing electric energy into the mechanical energy with dirving the load motion,The motor speed measurement and control test device is our Laboratory autonomic researched on the basis of the previous toraise our standards, It is not only use the characteristic test of a motor,but also prevent motor accidents, besides, the bedstand will discover rhe electric motor insulation aging, The device is characterized in that fast response、the ascendant measurement capability、non-contact measurement and the better real-time representation.Since the project interposed in many laboratory assistants, the chief task of mine is hardware design. Includes power section、protection circuit and the motor speed measurement based on photoelectric encoder. The signal handling equipment used in singlechip, to use photoelectric encoder for motor signal acquisition. designing of the phase demodulation、preamp module、filter circuit、communication and LED display module, besides of automatic alarm and power-off protection circuit. The bedstand applicables to various acdc receiver;Be used to velocity measurement, Reach the required or expected standard, To demonstrate the feasibility study for bedstand.
