The invention relates to the technical field of general product speed regulation, in particular to a hierarchical-speed regulation permanent magnetic speeder. The structure of the speeder includes two bearing pedestals, wherein one bearing pedestal is internally provided with a reamed hole bolt, one side of the reamed hole bolt is fixed with a transmission shaft I, the other side of the reamed hole bolt is connected with one end of a transmission sleeve, the other end of the transmission sleeve is connected with an end cap, the reamed hole bolt and the end cap are internally provided with a transmission shaft II through a bearing, and an electromagnetic speed regulation mechanism is arranged between the transmission sleeve and the transmission shaft II. The hierarchical-speed regulation permanent magnetic speeder is applicable to occasions requiring speed regulation, overcomes the technical problem that the speed of a conventional motor cannot be regulated, can be widely used in water pumps, fans, and other motors having load characteristic requirements and can be especially applied in industrial air cooling fans and water pumps, and can change motor speed with changes in load. Thus, about 60% energy can be saved.
Description
technical field [0001] The present invention relates to the technical field of general product speed regulation, in particular to a permanent magnet speed regulating device with graded speed regulation, which can be applied in the field of motor transmission equipment manufacturing, and can also be applied to electric power, petrochemical, mining, metallurgy, HVAC, water supply and Drainage and other fields, especially some harsh occasions where the environment is not suitable for other speed regulation methods. Background technique [0002] The workload of water pumps and fans often has the characteristics of non-constant power. The characteristic curve of the work shows that the output power increases and decreases with the speed. The method of installing a regulating valve or an air cut-off door, and the power of the motor is basically unchanged. Therefore, most of the load characteristics such as fans and water pumps in industrial and mining enterprises cannot change th...
