The editor of the deceleration stepper motor is a simple inventory of this article and introduces how to select the precision backlash of the deceleration stepper motor. I hope it will be helpful to you!

1. The reducer has backlash, also known as backlash, which is generated between two teeth. The highest-end harmonic reducer backlash is currently relatively small in use, and it is widely used in robot 6-axis manipulators. On machine tools, lithography machines and high-end equipment, the gear backlash of the reducer will have accumulated errors, that is, it will be accumulated after 1 revolution and 1000 revolutions. A stepper motor without a reducer has no cumulative error, and the accumulated error can be passed Return to the origin or return to 0 to solve.

2. It doesn’t matter if there is no requirement for power transmission with precision. Any reducer will do. Just look at the torque. If you are moving in position, it is recommended that you use planetary reduction stepper motors. This is the current accuracy is relatively high, and the price is relatively high. Cheap, domestically produced can be manufactured and sold in large quantities, and the market circulation is large. The planetary reducer is a great invention of mankind. It has the advantages of large carrying capacity, high precision, low price, and small size.
