What factors should be considered in purchasing stepping motors?
There are many types of motors in the market, among which high-quality and reliable stepping motors are widely used in many fields because of their outstanding advantages, therefore, more and more users want to buy this kind of stepping motor with simple operation.
So when users are faced with a variety of stepping motors, which aspects should they consider when choosing key points?
1. Driving method. As we all know, the conventional driving method of stepping motor can be divided into constant voltage driving and constant current driving, unipolar driving and bipolar driving.
Stable voltage drive refers to a stable drive voltage, which needs to be matched with an appropriate resistance value, while stable current drive is generally aimed at motors with small resistance.
However, unipolar drive and bipolar drive mainly lie in the difference in the number of power tubes in the drive circuit and the difference in the direction of coil current in the coil.
2, no-load starting frequency, stepping motor no-load starting frequency is generally called'Empty starting frequency'
This is an important goal in purchasing motors.
If it is required to start and stop frequently in an instant, and the rotating speed is very high, it is generally necessary to'Speed up the launch'.
If you need to directly start to reach high-speed work, choose reactive or permanent magnet motors. These motors'Empty starting frequency'
Both are relatively high, while hybrid stepping motors generally have low no-load starting frequency and do not provide this parameter. 3, phase number'Phase number'
It is the number of coil groups of stepping motors. Motors with different phase numbers have different working effects. The smaller the stepping angle, the smoother the stepping motor will work.
Generally, two-phase motors are used in most occasions, and it is more useful to select three-phase stepping motors in high-speed and high-torque working environments.
All in all, the purchase of stepper motors requires a few points to consider the above elements. In addition to the several aspects described above, we advocate that when selecting, attention should also be paid to whether the stepping motor has good waterproof, oil-proof and anti-corrosion properties, so as to better apply to special occasions, and if it is necessary to use special specifications of stepping motors, it is suggested to negotiate with manufacturers for customization.
