Must first determine the stepper motor drag torque load needed.
the simple method is on the load shaft with a lever, with the spring balance pull the lever and pulling force times the length of the lever is not only the load torque. Stepper motor drive can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of speed regulation and positioning. Or according to the load characteristic is theoretically calculated.
1. Due to the stepper planetary gear motor, the control class motor, so the current commonly used stepping motor torque is less than 45 nm, torque, the greater the cost is higher, if you choose the motor torque is larger or more than this range, can consider to add with the reduction gear.
2. To determine the stepper motor of high running speed. Stepper motor drive can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of speed regulation and positioning.
speed indicator in the selection of step motor is crucial, the characteristics of the stepper motor is with the increase of motor speed, torque is reduced, the lower speed is related to many parameters, such as: stepper 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 reduce the slower; The slower the motor phase current, the greater the torque to reduce. In design, 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 >.
3. Depending on the load heavy torque and high rotational speed of these two important indicators, then refer to 'the moment - Frequency characteristics >, you can choose the suitable stepper motor.
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 better one.
4. Consider leaving (after Such as 50%) Torque allowance allowance and rotational speed.
5. Can choose first, 选择) Hybrid stepping motor, if the price factor, can choose reactive stepper motor. Stepper motor drive can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of speed regulation and positioning.
6. Select subdivision driver as far as possible, and make the drive to work in the state of segment.
7. Select and when not to only look at this one index of the motor torque error, that is not the motor torque is bigger, the better, want to consider with speed indicator.
8. Subminiature drives and micro drive is to rely on the shell as the radiator, shall be fixed in a larger, thicker plates or additional cooling fan, if there is no cooling conditions, and drive to work in the low speed occasions ( Then drive fever is bigger) , you can choose 90 type drive instead of with fan.
