Shenzhen motor gear box factory, the gear has a variety of functions, so it can accelerate?If the gear change, can only get a very variable speed, can only have a few or dozens of fixed speed, the cost, not necessarily very high, and the gear change mechanism also has a problem is to change when the gear must stop turning, otherwise will damage the gear structure.But the great advantage of gear reduction is that the reduction in power is very small.Only the friction loss of the mechanical structure.That means you get a lot of torque after slowing down.
And the advantage of frequency conversion speed regulation is that you can achieve a wide range of stepless speed regulation, can then range of any speed, in the variable speed, the motor does not need to stop.The price of frequency converter is not very high now.The reliability of electronic products is much worse than that of mechanical products. Even normal operation is prone to problems.And there is also a problem is speed regulation in the rated speed is a constant torque speed regulation process, that is to say, it speeds down, but the torque has no change, that is, the output power of the motor decreased.It will not work on some load characteristic devices.This time needs to be used in conjunction with the gear change structure, let its speed in high speed and then decelerate under the gear change mechanism in order to get a large power.
