1326AD AC Servo Motor

How to choose AC Servo Motors

Points to check when selecting, with the values for this product (1326AD AC Servo Motor).

1. 1. Select rated torque suited to continuous load

   Confirm that the RMS torque over the entire operating cycle is within the rated torque. Convert the load torque including the efficiency and reduction ratio of transmission elements such as ball screws and belts, then select with margin. Listed models range from 1.27 to 2.4 N·m.

2. 2. Check maximum torque required for acceleration and deceleration

   Confirm that the peak torque required during acceleration and deceleration does not exceed the instantaneous maximum torque. Peak torque can only be sustained for a limited time, and the maximum current of the drive also sets an upper limit, so check the specifications of the matching amplifier as well.

3. 3. Review load inertia ratio against rotor inertia

   If the load inertia moment converted to the motor shaft is too large relative to the rotor inertia moment J, response will drop and vibration may occur. Choose a low-inertia model for high-speed response, or a higher-inertia model for stable control of large inertia loads. Check the manufacturer's recommended permissible ratio.

4. 4. Match required speed with maximum rotational speed

   Convert the maximum feed speed of the machine into motor rotational speed and confirm it is within the maximum rotational speed. Torque decreases at high speed, so use the speed-torque characteristics to confirm that the required torque is available in the range above rated speed.

5. 5. Match output capacity and mounting dimensions

   Since the drive capacity class is determined by rated output, confirm that the motor and amplifier are compatible. Also confirm that the flange size and shaft height allow mounting to the machine, and when replacing existing equipment, check the mounting holes and shaft diameter.

6. 6. Confirm holding brake and operating environment

   For vertical axes, select a model with a holding brake to prevent falling during power failure. A model with a brake has greater mass and overall length. In environments exposed to dust or water, check the protection rating (such as IP64 or IP65), and where vibration or high/low temperatures are severe, also check the type of detector.
