Case studies

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.

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.

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.

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.

Our customer was mandated by an Indian OEM so as to develop and locally manufacture a technology weakly established in this area so far. It dealt with a compact BLDC motor with an embedded electronic for a blower application in a light mobility vehicle solution. Controlling costs and development time were key criteria for the customer.

To meet these challenges, a simple brushless structure designed for mass-production was proposed to our partner. We also provided a relevant support for the embedded electronic development. Thanks to this, the product was launched on the market less than one year after kicking-off the project.

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.

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.

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.

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.
