Highly efficient solutions based on Leroy-Somer gear motors with energy-saving Dyneo® permanent magnet electric motors.
The creation of highly efficient solutions, equipment and technologies that allow customers to achieve maximum energy savings and maintenance savings has always been and remains the main criterion for the development of the Leroy-Somer company, thanks to which the company constantly finds new growth points.
All the equipment created by the company is the direct result of joint activities with customers and the pursuit of excellence.

Here is just a small list of questions that the manufacturer has already answered, putting them into the design of its equipment:
- Do you need to achieve the highest efficiency and energy efficiency of the entire electromechanical transmission?
- Do you need to achieve an increase in the output torque to 30% and at the same time maintain the overall size?
- Do you need to ensure a fixed speed or its regulation over the entire range while maintaining the constancy of the moment?
- Do you need to choose gear motors in the operating torque range up to 14,500 Nm?
- Do you need to ensure the ease of installation of the gear motor?
- Do you need to unify gear motors for your process equipment?
- Does your equipment work in different modes and conditions?
- Is it necessary to minimize the impact on the environment?
Currently, our company, together with Leroy Somer, is ready to offer you the latest generation of gear motors based on Dyneo® permanent magnet servo motors of the LSRPM, PLSRPM series. These electromechanical drive systems are, without exaggeration, one of the best in terms of efficiency available on the market today.
In combination with the Leroy-Somer frequency converter, both LSRPM and PLSRPM electric motors and electromechanical transmissions based on them provide the highest energy savings.
The use of this equipment in all operating conditions and modes is significantly more efficient than using asynchronous motors of class IE2 or IE3 (possible operating modes: adjustable speed, fixed or adjustable load, constant torque or quadratic torque, constant power).
By combining two highly efficient and high–performance solutions - gearboxes and electric motors, Leroy-Somer was able to offer the market a solution to the issue of significant energy savings in the form of high-tech electromechanical drives for modes with adjustable speed and high load factor.
Design features of increasing the efficiency of Leroy-Somer electromechanical transmission
The technology of gear reducers based on oblique teeth allows to achieve mechanical efficiency of over 95%. This technology makes it possible to install as close to the transmission shaft as possible, thus eliminating the need for intermediate parts such as a gear, chain or belt pulley, which gives additional savings of 15 to 20% in the efficiency of the working mechanism.
Another advantage of these new drive systems is a more compact motor; the size of the engine is reduced to half the size of the engines used in conventional technologies, thus the total weight of the gear motor is reduced by about 20% (which is half the weight of the engine).
Examples of savings in calculation for typical use cases
Transportation - an application area characterized by adjustable speed/load, with an intensity of use above 8 hours per day;Potential energy savings of the order of 30 - 50%.
Mixing/Mixer - a field of application characterized by constant power, with a potential intensity of use up to 24 hours per day;
The potential energy saving is about 15-20%.
Wind Generator - an application area characterized by adjustable speed/load in continuous operation;
Maximum energy output with minimum total weight.
Extrusion - an application area characterized by adjustable power in continuous operation;
Energy saving is achieved by optimizing the power used in accordance with the machine cycle.
