“Vehicle convenience features diversify, motor demand increases”

Motors, 50-60 per vehicle, high-end models have 100 or more
Infineon, One-Stop-Shop Total Solution and Support Tools

[Editor's Note] Among the mega trends in the automobile industry, the implementation of various functions that enhance vehicle convenience is emerging as a major trend. The introduction of automatic door/trunk opening/closing, built-in handles, electric curtains, electric seats, and vibration warning steering wheels, which did not exist in the past, is accelerating the increase in the adoption of motors in vehicles. Accordingly, motor control solutions are required for various devices, and the demand for meeting various standards and safety criteria is also increasing.

Meanwhile, Infineon will hold a webinar on the topic of low-power motor solutions on November 5. Infineon Korea Automotive Business Division Manager Kim Hyo-hoon will present a webinar on the topic of 'Low-power motor solutions and their use in body applications for improving vehicle convenience and safety.' We met with Manager Kim Hyo-hoon ahead of time to talk about the latest trends, Infineon's motor solutions, and an introduction to the webinar.

■The number of motors in vehicles has been increasing recently. The reasons for the increase in the use of motors and demand for motors in vehicles are as follows:

When we say 'motor' in a vehicle, we usually think of the drivetrain motor, also known as the traction motor. However, in reality, motors are widely used in various devices for user convenience, such as side mirrors, power seats, power windows, and wipers. Usually, about 50-60 motors are installed per vehicle, and in the case of high-end vehicles, over 100 motors are installed.

As convenience is mentioned as one of the recent mega trends in the automobile industry, the demand for motors is increasing as various functions for the convenience of passengers are required in recent vehicles compared to the past.

In addition, as safety standards and awareness have greatly improved, the demand for safety features that require motors, such as Electric Power Steering, Electric Parking Brake, and Reversible Seatbelt Pretensioner, is also increasing.

■Introduction and special features of motor solutions provided by Infineon

Infineon's motor driver products have proven high reliability and performance. Infineon's motor solution, MOTIX™, has the following special features:

First, Infineon has various solutions to satisfy various customer requirements. Infineon motor solutions are not only driver ICs for motor driving, but also have a diverse lineup of components required for motor driving, such as LDOs, transceivers, and MCUs. Therefore, it can provide the optimal solution suitable for various development environments and requirements of customers.

Second, Infineon has a total solution. As a 'One-Stop-Shop', it supports the most suitable product through a variety of lineups in terms of hardware, and also provides various support tools such as libraries and device drivers to shorten the user's development time in terms of software.

Depending on the need and application, reference boards and their design contents are also provided, so you can refer to them and apply them directly to your development application.

■Infineon's software solution for precise control of DC/BLDC motors

As demand for BLDC motors increases in recent body applications, more complex and precise control is required, including the need to implement control algorithms in software.

As mentioned earlier, Infineon provides a motor control example library to support this. If you are using a product with an MCU built in, there are also ways to get licensed software support directly.

Additionally, for products without a built-in MCU, device drivers are supported for each product, so there is an advantage in that registers and device settings can be conveniently set regardless of which MCU is used.

■Low-power motor application case for Infineon vehicle body applications

Infineon's motor solutions are used in a wide range of applications worldwide, to the point where it would be difficult to mention all examples. In particular, Infineon products are widely used in all motor solutions used in body and chassis applications of vehicles.

■A brief introduction to the November 5th webinar on low-power motor solutions and their use in body applications to improve vehicle convenience and stability

In this webinar, we will look at the latest trends in automotive motors, introduce Infineon's automotive motor solutions, and learn about the system configuration and operation required to drive the motor. We hope that this will be a useful time for everyone interested in low-power motors applied to automotive body and chassis applications.
