Folding common types of geared motors

1) The main characteristics of the AC Motor Worm Gearbox is a reverse self-locking feature, you can have a greater reduction ratio, the input shaft and the output shaft axis is not the same, nor in the same plane. But generally larger, the transmission efficiency is not high, accuracy is not high.
2) Harmonic Harmonic Drive gear motor is controlled using a flexible element is elastically deformed to pass the motion and power, small size, high precision, but the downside is limited flexible wheel life, the impact of intolerance, rigidity and metal parts compared to the poor. Input speed is not too high.
3) the advantage of helical worm gearmotor structure is compact, small backlash, high precision, long life, rated output torque can do great. But the price is slightly more expensive. The input shaft of the gear teeth less output shaft of the large gear motors are generally used for low speed high torque transmission device, the internal combustion engine or other high speed electric motor powered by a gear motor to achieve the reduction goal, Common Geared motors on the same principle will also have a few gears to achieve the desired reduction effect than the size of the gear teeth is gear ratio.
