Reliability and service life

The reliability of Leroy-Somer solutions is due to proven and tested construction choices, including:

• Balancing classes that significantly reduce internal vibrations
• Electrical and mechanical dimensioning incorporating a thermal reserve to increase the service life of the windings
• Special surface treatments for increasing resistance to harsh environments
• Very high degree of concentricity of the bearing unit to increase the service life of the bearings
• High-efficiency solutions that reduce the temperature rise in the motors and increase their service life

Tried and tested technologies

To meet the expectations of manufacturers, operators and engineers, Leroy-Somer is at the forefront of fixed or variable speed drive technologies.

A network of specialists at your service Leroy-Somer solutions guarantee torque performance, fully matching application requirements.

The electrical and mechanical dimensioning of auxiliary drive systems allow machines to be installed in confined spaces.

Permanent magnet drive system solutions, integration of control electronics, and the choice of liquid cooling are alternatives for achieving still higher levels of compactness.
