      What is an Automotive Motor Control System?

      How do you think the new power steering system work with minimal force applied by the driver? How does a seat go forward, backward, up and down with a push of a button? The answer of both these question is the automotive motor control system.

      In the simplest terms, a motor control application is a set of hardware and software components that drive a motor or multiple motors. These motors, in turn, perform actions such as opening-closing of windows, power steering movement and more.

      Type of motor control system

      Open Loop Motor: The motor control applications in which the quality of the output does not impact the input to the motor control process is called an open loop motor control system. It implies that they are open-ended system that do not have any feedback mechanism.

      Closed Loop Motor: A closed loop motor works on feedback mechanism and hence, it is also called feedback control system. An error signal is generated by the Gate Driver IC in case the actual output is different than the desired output. This error signal will go to the motor controller which will take necessary actions. In a way, it is a self-correcting motor control applications.

      What are the components of a Motor Control System?

      Microcontroller: This is where the motor is controlled from. Microcontroller will have the pulse-width modulation (PWM) control and other motor drive logic.

      Gate Driver Unit: This Integrated Circuit acts a power amplifier. It will accept a low-power input from the motor controller IC and gives high-power input to a switch that transfers it to the motor.

      MOSFETs: These are switches that will again amplify the signal received from the gate drivers. This signal will be passed to the stator of the motor causing an Electro Magnetic Flux, EMF.

      H-Bridge: H-bridge is again a circuit that helps a DC motor to run in both clockwise and anti-clockwise. It can apply the voltage to a load in any direction and this how it controls the direction of the motor.

      Motor: Motors can be DC, AC, Brushless, brushed etc. They are used depending on the use cases and the application.

      So, in order to run the motor, a set of data (PWM signals) flows from microcontroller to the motor via the gate drivers and MOSFETs.
