AC Motors Basics Web based Training / 交流电机基础网络课程 (W1201)


  • Electrical drive technology plays an important role in industry, mobility and infrastructure. A general knowledge of drives systems is therefore essential for the performance of planning, commissioning and maintenance work. This training session introduces you to this subject. It gives you a basic understanding of what you need to know to achieve optimal learning results from SITRAIN courses at the training center.
