In order to further improve the drive systems of high frequency response, can use litre frequency boost power driver interface. The interface provided by the winding voltage and the operating frequency of the motor into linear relationship. it's main circuit is actually a switch regulated power supply, use of frequency -Voltage converter, drive pulse frequency conversion into dc level, and the level to control switch regulated power supply input, this constitutes a frequency feedback power driver interface. stepper motor and stepper motor drives stepping motor driven system. The performance of the stepper motor drive system, not only depends on the performance of the stepping motor itself, also depends on the advantages and disadvantages of stepper motor drives. The study of stepper motor driver is almost a simultaneous and stepper motor. because of stepping motor is controlled, so the current commonly used stepping motor does not exceed the maximum moment of 45 nm, the greater the torque, the higher the cost, if you choose the motor torque is larger or more than this range, can consider to add with the reduction gear. if you think you choose the machine is too large, can consider to add reduction gear, so that we can save cost, also can make your design more flexible. To choose appropriate reduction ratio, to considering the relationship between torque and speed, choose the best solution. subminiature drives and micro drive is to rely on the shell as the radiator, shall be fixed on the larger, thicker metal plate or additional cooling fan, if there is no cooling conditions, and drive to work in the low speed setting (Then drive fever is bigger), you can choose 90 type drive instead of with fan. speed indicator in the selection of step motor is crucial, the characteristics of the stepper motor is with the increase of motor speed, torque, the falling speed is related to many parameters, such as: motor drives the driving voltage, phase current, the phase inductance, the size of machine and so on, the general rule is: the higher the driving voltage, torque decline more slowly; The more slowly the motor phase current, the greater the torque. in the design, we should make the motor speed control in 600 r/min, or within 800 r/min, say that is not standard, of course, you can refer to the < moment -Frequency characteristics >. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
