Electric Motors

Electric motors are the heart of all electric drives. That is why LSP has been able to bundle 20 years of the experience necessary for developing and manufacturing customized electric drives. Our application spectrum ranges from servomotors in highly dynamic and precise systems to high-voltage motors for the automotive sector. We develop and produce our electric motors in-house at our facility near Munich.

What we offer:

LSP has a broad portfolio of electric motors that can be cost-effectively scaled to your specific application. If you need a customized drive solution, we can offer you an application-oriented redesign to meet your requirements. Our range of services includes the development of rough designs to the production and measurement of electric motors. Due to our specialization in prototypes and small series manufacturing, we are then able to offer short development and delivery times for finished prototypes. The advantage for you: early functional testing including validation of the final product.

Your advantages at a glance:

  • Extremely short development times
  • Products tailored to your application and cost structures
  • Broad existing portfolio means cost-effective development
  • Close collaboration during the entire project
  • In-house production of electric motors, up to small series quantities (10-1000 pcs. per year)
  • Testing and measurement of motors with suitable test benches

When developing electric motors, LSP works in compliance with the highest standards (ISO 9001, DIN 60034) and uses state-of-the-art methods. The design process at LSP includes all areas relevant to your needs: functionality, feasibility and costs. Thanks to many years of experience with complete systems, we inherently take into account all system-related aspects of a given motor and its purpose. Special attention is also paid to the interaction of electric motors, inverters and mechanical applications.

Our areas of expertise:

  • Electromagnetic design
  • Development of thermal designs and cooling concepts
  • CAD design incl. tolerance analyses and FEM structure analyses
  • Vibration analyses and acoustic optimization
  • Dynamic system simulations of electric motors on HiL test benches
  • Optimization for overall performance, including inverter
  • Application-specific design taking into account cost targets for small and large series production

LSP has a large portfolio of electric motors that can be customized to the scale of your customer requirements. We would also be happy to develop an individual concept to suit your specific needs!
