Power amplification power amplifica

Power amplification power amplification is the most important part of the driving system. The torque of the stepper motor at a given speed depends on its dynamic average current rather than its static current (which is the current on the sample). The greater the average current is, the greater the torque of the motor is. Therefore, different driving methods are adopted in different occasions. So far, the driving methods generally have the following: constant voltage, constant voltage series resistance, high and low voltage driving, constant current, fine fraction, etc. In order to improve the dynamic performance of the motor as far as possible, the signal distribution, power amplifier components of the stepper motor drive power supply.
