What is a magnetic rotor?

Magnetic rotors are integral to high performance, highly efficient electric machines in a range of industries including:

  • Aerospace and defense
  • Industrial
  • Automotive
  • Energy regeneration

Why dynamically balance magnetic rotors?

Magnetic rotors often operate at very high speeds and require very tight tolerances – even the smallest amount of unbalance due to centrifugal forces during rotation will cause the assembly to vibrate. If left undetected, and as the rotational speed increases, so will the vibration, resulting in damage and premature component failure.

Dynamically balancing the magnetic rotor assembly will remove or minimise imbalance, allowing the rotor to run without vibration, and in turn extend its lifespan.

Why choose WDB Ltd?

With over 50 years’ experience delivering exceptional dynamic balancing services, the WDB Ltd team have an unrivaled depth of knowledge across a range of industries.

We are able to achieve extremely tight tolerances, using specially made non-magnetic equipment. Our handling expertise and use of protective materials means that the risk of foreign object damage (FoD) during balancing is greatly reduced.

In addition, our high precision balancing machines have the capacity to dynamically balance any rotating part from just a few grams to 30 tonnes. We also balance to any ISO grade such as G0.4 to G6.3, and over a wide range of service speeds.

Improving the service life of your magnetic rotor assembly

Specialist dynamic balancing will improve the service life, accuracy, and quality of your machinery by efficiently highlighting unbalanced components, saving your money in the long-run.

An in-house dynamic balancing service that is second-to-none

We pride ourselves on our excellent service to our customers, with short turnaround times to suit your requirements and a 24-hour breakdown service. On completion of the job, you will be provided with a Certificate of Conformity and detailed reports to suit your individual needs. Delivery and collection can also be arranged for you if required.
