Deceleration motor many clients of micro planetary reduction device and a long-time operation, speed reducer is temperature. 1, micro gear motor is also called the planet gear motor, which is often said that the load is greater than the rated load factory rules, this is due to the large load, internal gear reducer, friction increases, caused the larger load. 2, internal structure is not suitable for speed reducer input, there is customer response, the same motor installed in the same speed reducer is reducer reduction ratio is different, but different noise and fever, but what is this reason? Through effective inspection and analysis, we found that the heat is severe reducer input level of tooth is bigger, the sun at this time the sun gear deceleration exercise, planetary gear do accelerated motion, the natural heat is bigger. In order to solve the problem of this kind of attack, using other reduction ratio reducer, or change the internal gear structure (Capital is larger)。 Micro planetary gear motor manufacturer, of course, a lot of, career is not very consistent, but generally rendering speed reducer is main or above two reasons for overheating.
