How to Select and Apply The Precision Backbacklash of Deceleration Stepper Motor

1. the reducer has a backgap, also known as a backlash, is generated between two teeth, now the highest end of the harmonic reducer backlash is currently in use is relatively small, widely used in robot 6-axis manipulator, height machine tools, and lithography machines and high-end equipment, the reducer backlash will have a cumulative error, that is, turn 1 and turn 1000 times will accumulate, The stepper motor without reducer has no accumulated error, which can be solved by returning to the origin or returning to 0.

2. If there is no requirement on the precision of power transmission, it does not matter what reducer, just look at the bearing torque is enough, if the position of the recommended choice of planetary deceleration stepper motor, this is the current high precision, the price is relatively cheap, domestic can mass manufacturing sales, market circulation, planetary reducer is a great invention of human, bearing capacity is large, High precision, cheap price, small size and other advantages.

3. My company launched the 42MM planetary deceleration stepper motor annual production and sales of more than 30,000 units, The total thickness of motor + reducer is controlled at 58.8MM and the torque can reach 2.7NM. The model is 42PG010-D14-0434. There is another 42PG010-D20-0448 motor + reducer whose total thickness is controlled at 72.3MM and the torque can reach 5.3NM. In addition, the thickness of 57MM and 60MM stepper motor can be controlled to 85.8MM, which can replace the right Angle reducer chosen by users, because the right Angle reducer is too expensive.
