Stepper motor attention points in the application

1.Stepper motor is used in low-speed occasions---the speed per minute does not exceed 1000 rpm, (6666PPS at 0.9 degrees), preferably between 1000-3000PPS (0.9 degrees), which can be used to work here through the reduction gear. At this time, the motor has high working efficiency and low noise.

2.It is better not to use the whole step state of the stepping motor, and the vibration is large in the whole step state.

3.For historical reasons, only the motor with the nominal 12V voltage uses 12V. The voltage value of other motors is not the driving voltage volt value. The driving voltage can be selected according to the driver (recommended: 57BYG uses DC 24V-36V, 86BYG uses DC 50V, 110BYG uses 80V higher than DC. Of course, 12V voltage can be used in addition to 12V constant voltage drive, but other temperature can be used. 

4.The load with large moment of inertia should choose the motor with large frame size. 

5.When the motor is at a high speed or a large inertia load, it is generally not started at the working speed, but the speed is increased by gradually increasing the frequency, and the motor does not lose the step. Second, the noise can be reduced and the positioning accuracy of the stop can be improved.

6.When high precision, it should be solved by mechanical deceleration, increasing the speed of the motor, or using a high subdivision number of drives, or a 5-phase motor, but the price of the whole system is relatively expensive, the manufacturer is less, and it is eliminated. The argument is a layman. 

7.The motor should not work in the vibration zone. If it must be solved by changing the voltage, current or adding some damping.

8.The motor works below 600PPS (0.9 degree) and should be driven by small current, large inductance and low voltage.

9. The principle of selecting the motor after selecting the motor should be followed.
