Description

technical field [0001] The invention belongs to the technical field of speed regulation and control of three-phase asynchronous motors, and in particular relates to an intelligent frequency conversion speed regulation device suitable for pulse loads and a control method thereof. Background technique [0002] With the development of science and technology, motors are used more and more widely, and the load forms used are also diversified. One of the most important forms is the pulse load form. For example, it is widely used in fitness equipment such as treadmills. With pulse load. [0003] The pulse-type load in the treadmill means that the load torque generated by the user when running or walking is a pulse-type load torque, which is mainly determined according to the frequency, duty cycle and load torque amplitude of the pulse-type load torque. describe. [0004] The operating characteristics of the motor under the pulse load are very different from those of the ordinary ...
