Failure Analysis of Electric Motors and Innovative Solutions
Training course supplementing “An Insight into Electric Motors”
Learn how you can improve the service life and efficiency of electric machines during design and development This training is offered as a 1-day course.
Duration
1 day
Prerequisites
Knowledge of electrical machines
Software used
Software-independent
- Recognizing the parasitic effects of motors which use inverter supplies
- Avoiding instances of failure and increasing service life by innovative solutions
- Recognizing and eliminating the causes of unwanted noise
- Learning about measures commonly employed to limit motor losses
Description
When employed in the context of electric mobility and in many other modern applications, electromotors are controlled by power electronics. A broad variety of problems arise both since inverter supplies must be used and due to the ever-increasing utilization of electric motors: vibration and irritating noises are as much of a problem as losses and capacitive bearing currents. This training involves the use of lots of examples to enable you to become familiar with a variety of unwanted effects that occur during the operation of electric machines that use inverter supplies. You will learn ways in which expensive failures can be avoided through the use of constructive solutions and get to know the causes of unwanted noise and how you can eliminate it. To finish with, you will be familiarized with the measures commonly used to limit motor losses.
This training course is targeted at designers and developers from the realms of electrical engineering/electronics, drive mechanisms, and motor design who both understand the causes of parasitic effects in electric machines that use inverter supplies and who wish to reduce the impact of these effects. Mechanical engineers, mechatronics engineers, physicists, and engineers from other fields can also make use of this one-day special seminar to deepen their grasp of current expertise in relation to electric motive power engineering.
