Problems solved by technology

However, in practical situations, most of the motor platforms are large in size and difficult to operate, which is dangerous to a certain extent. Moreover, there is only one type of motor in many platforms, and it is impossible to observe the experimental phenomenon when multiple motors cooperate. In addition, , many motors can only work under a single voltage condition, and there is also a lack of richness in learning and research

Description

technical field [0001] The invention belongs to experimental instruments, and is a small-power multi-type motor series experiment platform, which is applied to electrical and automatic motor control and power electronics experiments in colleges and universities, and belongs to the field of teaching and research equipment. Background technique [0002] At present, in major education colleges and universities, some undergraduates or postgraduates who study power electronics, electric drive, and motor drive often need to apply practical motors that meet the research content for research and learning during the learning process. However, in actual situations, most of the motor platforms are large in size and difficult to operate, which is dangerous to a certain extent. Moreover, there is only one type of motor in many platforms, and it is impossible to observe the experimental phenomenon when multiple motors cooperate. In addition, , many motors can only work under a single volt...
