Tips: Advantages of CCHN 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.
