Case studies

We help you solve a wide variety of problems related to the development of high-level mechatronic solutions: responsiveness, superior knowledge of electromagnetism, multi-physical approach, integration, time-to-market, and compatibility with efficient mass production. 5 examples.

Eliminating technological barriers

Customer’s problem

One of our customers, experts in the manufacture of mechanical pumps, was developing an electrified pump for the first time: 18 months from the start of production, they reached a technological impasse.

MMT solution

We offered them a brushless motor solution based on one of our technologies. We helped them develop the product with a technology transfer, which allowed them to be ready on time.

Simplifying processes

Customer’s problem

One of our customers was tasked with delivering to an automotive transmission systems manufacturer a position sensor in the form of two sub-assemblies, one mounted on the transmission shaft, the other on its housing. The usual solutions (sub-assembly pairing, specific calibration at the end of the production line, etc.) for meeting the precision requirements despite the large mechanical tolerances were too expensive.

MMT solution

We offered them a magnetic sensor solution based on one of our technologies.Extremely robust to mechanical tolerances and therefore intrinsically very precise, this solution made it possible to avoid the final calibration step and to use the sub-assemblies without any pairing.

Passing tests

Customer’s problem

A car manufacturer asked us to produce electric motor prototypes as well as an electronic control for electrifying a heat engine function. The objective was to carry out tests on an engine test bench in order to assess the usefulness of the overall function. Because these tests are expensive, it was important for the device to work properly the first time.

MMT solution

As a result, and in addition to the challenges related to the development of the motors and electronic control, we worked with this manufacturer to develop a representative test bench, whichwas built at MMT. The goal was to deliver approved and functional components. The customer was able to carry out the tests without delay.

Adapting to the control architecture

Customer’s problem

Several automotive suppliers asked us to develop an electrical control valve in an extremely small space and for which existing actuators, using DC motors, were no longer suitable. The new solution had to remain compatible with the vehicle’s centralized electronic controls.

MMT solution

We devised a smart combination of simple and compact brushless motor technology, an integrated position sensor and an innovative electronic interface. MMT was able to offer an elegant and truly different solution, while remaining compatible with the electronic control architecture in place.

Being robust and affordable

Customer’s problem

As part of the development of a magnetic position sensor for 2-wheelers, one of our customers faced an extremely high level of magnetic field disturbance, which degraded the accuracy of this sensor unacceptably. The shielding solution they had put in place proved to be very expensive.

MMT solution

We worked on one of our position sensor technologies to develop a specific magnetization solution that maximizes magnetic field density, with reduced sensitivity to the interfering fields. MMT was able to offer a profitable solution for the customer, which is both sufficiently precise and minimizes the need for additional shielding.
