Motor Control Units

Motor Control Unit (MCU) for Brushless DC Motor (BLDC Motors)

A customer-specific control unit from KYOCERA AVX (Salzburg) provides significant advantages for integration into the electric motor and into the existing installation space. The modules contain all the necessary components for the control of a brushless DC motor (BLDC motor). Their design is adapted, via the selection of the electrical components and the mechanical fasteners, also to the smallest installation space requirements and coordinated perfectly with the respective application. The comprehensive know-how of several product generations is used via sophisticated thermal and mechanical simulation. Each control unit meets the requirement of a perfectly coordinated solution with regard to space, reliability, manufacturability and cost efficiency. The specially developed contact and connecting elements also contribute to this and permit optimal connection to the external connector and, besides the mechanical reliability, provide an important cost advantage. Increasingly shorter development times in the automotive industry are achieved via specially developed platforms for hardware and software solutions. In that way it is possible to make the first prototype available within a few weeks and to successfully implement a closely coordinated project schedule as far as series production. All the platforms can be adapted at any time to the needs of other applications and automobile manufacturers. This applies to the power (30 W – 10 kW), to the on-board voltage (12 V – 810 V), and to the required communication (PWM, LIN, CAN) with the control unit.
