Failure Analysis of Electric Motors and Innovative Solutions

Training course supplementing “An Insight into Electric Motors”


Training Advanced

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.

1 day

Knowledge of electrical machines

Software used

  • 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


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.

Do you have questions on the training?

When will I receive the final confirmation for my training booking?

Straight after you sign up, an automatic confirmation of receipt will be sent to the email addresses you provided. Once you have successfully verified the data you provided, you will receive your personalized sign-up confirmation, containing further information on course fees, the billing address, etc., by email within two to three working days.  

As soon as the minimum number of attendees has been reached, you will receive a final training confirmation containing further information. If you have booked an on-site training, we recommend that you wait until you have received this final confirmation before booking your travel and accommodation.

If the minimum number of attendees is not reached, we reserve the right to cancel the training seven days before it is due to start at the latest. We are happy to inform you on changing your booking to an alternative date. Please note that we accept no liability for hotel or travel bookings that attendees have already made.

When is the sign-up deadline for a training?

Training places will generally be allocated based on the order in which attendees sign up. For this reason, we always recommend booking for your desired date as early as possible.

As long as a coures still has free places, it can be booked.

At what time do the training courses begin and end?

Usually the training courses start at 9:00 am and end at 5:00 pm of the respective local time. The actual course times will be stated in the booking confirmation. Please note that, depending on the training host, there may be a possible time shift between your and the provider's local time. Therefore all local times are provided with the valid time shift to Greenwich Mean Time (GMT).
