    FAQs Regarding Motor Controller for Electric Vehicles

      Ans. Our platform for motor controller for electric vehicle is completely customizable, configurable and ready-to-deploy solution for your Electric Vehicle Applications.

      We have designed a suite of Base Software, that consist of the Hardware Abstraction Layer (HAL) and Low-Level drivers (LLD). This Base Software can be customized for integration with your Application layer, helping you save substantial development time and cost (approximately 6-8 months).

      As an additional value-add, a critical software module of the Application layer, which is Field Oriented Control (FOC) algorithm, has also been implemented and can be readily integrated with your system.

      Depending on the project’s requirements, we can also partner for the development of other modules like regenerative braking, speed and torque limiting and so on, for the application layer.
