What do China small stepper motor suppliers tell you about the basic precautions for stepper motor applications?
Stepper motor is an open-loop control element which Converts Electric Pulse Signal Into Angular or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulse signal, but not affected by the load change, that is, add a pulse signal to the motor, the motor turns a step angle. The existence of this linear relationship, coupled with the stepper motor only periodic error and no cumulative error and so on. It makes it very easy to use stepper motor to control speed and position.
1. The stepper motor can be used in low speed fields, i. e. , revolutions per minute is less than 1000 RPM, it is best used in 150-450RPM, the motor can be made to work in this area by the speed reduction device, at which time the motor works with high efficiency and low noise.
2, stepper motor is best not to use the full-step state, the full-step state vibration.
3. For historical reasons, only motors with a nominal voltage of 12V use 12V, the voltage of the other motors is not the voltage of the driving voltage, drive according to the driver choice, dynamic Voltage (recommendation: 42 motor uses DC 12V-24V, 57 motor uses DC 24-36V) , of course, 12 volts of voltage in addition to 12V constant voltage drive can also use other driving power, but to consider temperature rise.
4, the load with large moment of inertia should choose the motor with large base number.
5. When the motor is under high speed or high inertia load, it does not start at the working speed, but raises the speed gradually, one motor does not lose its step, the other can reduce the noise and improve the positioning precision of stopping.
6, high precision, should be through mechanical deceleration, increase motor speed, or the use of a high fraction of the driver to solve.
7. The motor should not work in the vibration zone, if necessary by changing the voltage, current or add some damping solution.
8, motor in 90RPM below work, should use small current, large inductance, low voltage to drive. 9. The principle of selecting motor first and driving later should be followed.
