Tips: Advantages of ATO stepper motor linear actuator
- It has all the advantages of the traditional DC motor and also cancels the structure of carbon brush and slip ring at the same time.
- It can reduce low speed and high power operation and the load of reducer direct drive.
- It has small volume, light weight and great power.
- It has excellent torque characteristic, good torque performance at middle and low speed, large pull-in torque and small starting current.
- It has infinite speed variation, wide range of speed regulation and strong overload capacity.
- It has soft start, soft stop, good brake characteristic, which can save the original mechanical brake or electromagnetic brake device.
- The efficiency is high, the motor itself has no excitation loss and carbon brush loss, which eliminates the multistage reduction consumption, and the comprehensive electricity saving rate can reach 20%~60%.
- It has high reliability, good stability, strong adaptability, simple maintenance.
- It is resistant to vibration and has low noise, small vibration, smooth operation, long service life.
- It has no radio interference, no spark, especially suitable for explosive sites.
