【Abstract】 Based on the subdividing technology of step motor with the constant amplitude current vector and even rotation, the subdividing driven circuit with amplified power arising from directly amplified voltage has been designed. With the method of data table generated by computer and manual adjustment, the linearity between the step angle and the number of subdivided step has been obtained. The evenly subdividing angle reaches 0025°. Experiments show that the system works stably and has a good repeatability.更多还原
