How to choose Speed reducers

Points to check when selecting, with the values for this product (Compact High-Precision Gear Reducer APG Type for Servo Motors).

1. 1. Determine the reduction ratio from the required speed and torque

   This product: Reduction Ratio 1/3～1/100

   The output rotational speed equals the motor rotational speed divided by the reduction ratio, and the output torque is approximately the reduction ratio times the input torque (minus transmission efficiency losses). Determine the rotational speed and torque required on the load side first, then select a reduction ratio that satisfies both.

2. 2. Provide margin in the permissible output torque

   Confirm that the rated output torque of the output shaft exceeds the load torque. Because torque beyond the rating is applied during startup and stopping, also check the permissible peak torque at startup and stop (as a percentage of rated torque; for example, some products are rated at 350%).

3. 3. Check the motor capacity to be combined

   This product: Applicable motor capacity 100W～3000W

   Each reducer has a specified motor output that can be mounted. If the motor capacity is too large, the torque after reduction may exceed the permissible value, so select within the applicable motor capacity range and also confirm compatibility of the mounting flange.

4. 4. Backlash according to positioning accuracy

   This product: Backlash 3 min / 15 min

   Backlash is the play in the rotational direction of the output shaft, measured in arcminutes (1/60 degree). For positioning and reciprocating motion, smaller is better; some products are available in 1 arcminute or 3 arcminutes, and some traction drive products offer no-backlash operation.

5. 5. Select the shaft category that suits the equipment layout

   The choice of coaxial, parallel or right-angle shaft changes the arrangement inside the equipment. Right-angle shafts allow a reduced depth through right-angle mounting, and hollow shafts allow a mating shaft to be inserted directly. Also check whether leg mounting or flange mounting is required.

6. 6. Check input speed and external dimension constraints

   For high-speed operation, confirm that the instantaneous maximum input rotational speed (for example, 7000 r/min) is not exceeded. Also verify at the design stage that the outer diameter fits the installation space and whether the unit can replace an existing product with identical dimensions.
