耗能较大的电动机一旦制动发电,反馈的电能十分可观。如果将这部分电能回收,对整个社会节能降耗的意义巨大。电动机在现今各个领域得到极其广泛的应用,因此电动机成为了耗能大户,它将电能转换成机械能或热能,消耗了大量电力资源。但在特殊工况下,如电动机 Once the energy-hungry motor is braking, the feedback power is very impressive. If this part of the energy recovery, the entire society is of great significance in saving energy and reducing consumption. Electric motors are extremely widely used in all areas of the world today, making electric motors a power hungry, converting electric energy into mechanical energy or heat and consuming large amounts of electricity. However, under special operating conditions, such as motors
