The advantages of the customized stepping motor are as follows: 1. The rotation Angle of the motor is proportional to the number of pulses; 2.
2. The motor has the maximum torque when it stops (when the winding is excited);
3. Because the accuracy of each step is between 3% and 5%, and the error of one step will not accumulate to the next step, the position accuracy and movement repeatability are better;
4. Excellent start-stop and reverse response;
5. Because there is no brush, the reliability is high, so the life of the motor only depends on the life of the bearing;
6. The response of the motor is only determined by the digital input pulse, so the open-loop control can be adopted, which makes the structure of the motor relatively simple and controls the cost;
7. Extremely low speed synchronous rotation can be achieved by simply connecting the load directly to the motor shaft.
8. Since the speed is proportional to the pulse frequency, there is a relatively wide speed range.
The operating torque-frequency characteristic of stepper motor is the curve of the relationship between output torque and frequency measured under certain test conditions.
Practical formula: speed (R /s)= pulse frequency /(motor number of steps per revolution * fine fraction)
V: Motor speed (R/S);P: Pulse frequency (Hz);E: Motor proper step Angle;M: Fine fraction (whole step is 1, half step is 2)
