Tips: Current chopping drive method of stepper motor
Current chopping drive is the stepper motor winding current value converted into A certain percentage of the voltage, and the comparison between the D/A converter output preset, compare the results to control the switch to power tube, so as to achieve the purpose of the control winding current.
Advantages: Make the characteristics of the movement control simulation sine waves, greatly improve the performance, speed and noise is small, can use higher segmentation, is the current popular control method.
Weakness: The circuit is more complex, the circuit is difficult to control and the theory of interference fit requirement, the prone to jitter, formed in the control of sine wave peaks and troughs, easily lead to the high frequency interference, resulting in driving element fever or aging due to high frequency, which is easy to appear when a lot of drive to use more than a year the main reason for the red light protection.
