1. Background to the recent increase in demand for in-vehicle motors

Modern cars are equipped with dozens, or even hundreds, of motors, and this number is only increasing. The main reasons for the increasing demand for in-vehicle motors are:

Environmental standards: In order to meet vehicle emission reduction targets, demand for electric vehicles (EVs) and hybrid electric vehicles (HEVs) is increasing, as these vehicles require motors for driving and generating electricity.

Safety standards: As technology such as digital controls for automobiles improve, the use of motors for automatic braking and automatic parking functions in vehicles is becoming more common.

Increased comfort: Cars are equipped with a variety of features that improve comfort, and an increasing number of motors are used for air conditioning, power steering, window lifts, sunroofs, power seats, etc.

As a result, the demand for in-vehicle motors is increasing to improve the environment, safety, and comfort.In addition, the demand for in-vehicle motors is expected to continue to increase due to the electrification of automobiles and the evolution of autonomous driving.

2. Challenges and Solutions for Motor Application Development

The Multi Motor Evaluation Kit accelerates development by overcoming the challenges that arise when starting to develop a motor application for the first time.

Task	Solution
We are considering developing a motor application, but are unsure of the steps to begin selection and evaluation.	The MULTI MOTOR EVALKIT is built with market-proven chipsets, so it is guaranteed to work.
No experience in developing BLDC motor control software.	The MULTI MOTOR EVALKIT comes with a sample driver library for TLE9563-3QX and integrates motor control software (reviewed code) that supports field-oriented control algorithms. The sample source code allows you to check the operation of the BLDC motor in just a few steps.
I need to control multiple motors simultaneously, and I'd like an evaluation board that meets my needs.	The MULTI MOTOR EVALKIT is designed for applications that control multiple motors, supporting two BLDC motors and up to 18 DC motors.
There are security/safety requirements for motor control microcontrollers, and we are looking for a suitable microcontroller.	The Infineon automotive microcontroller CYT2B78CADQ0AZE installed in the MULTI MOTOR EVALKIT is ISO-26262 and ASIL-B compliant and implements HSM, making it applicable to safety/security requirements.

3. Ready to evaluate BLDC motor control

Infineon provides a ready-to-operate BLDC motor control sample for the TRAVEO™ T2G and MOTIX™ SBC TLE9563-3QX mounted on the MULTI MOTOR EVALKIT, so customers can start evaluation immediately and without hassle by simply preparing an evaluation environment and an appropriate BLDC motor.
