Motor Control Overview
Recommended MCUs & MPUs for Motors
Renesas provides motor control solutions to support the entire development process: devices that are particularly suitable for motor control, a motor control kit that can be used as a reference design, and complete software and tools.
Motor Types
Since this type of motor is driven by a DC power supply, it is also called simply a DC motor. To distinguish it from a permanent magnet synchronous motor (brushless DC motor), here we will call it a brushed DC motor. Since it is comparatively economical and easy to drive, the brushed DC motor is used for a broad range of applications.
Motor Control Algorithms
The field of motor control has undergone rapid expansion due mainly to the advantages of semiconductors in both power and signal electronics and the processing capability of micro-electronic microprocessors and DSPs.
Motor Control Solution
Renesas provides solutions that strongly support customers' development. We are preparing a number of solution such as devices suitable for motor control, a motor control kit that is a reference design, software and tools that you can easily try from what you want to do from learning to development.
Renesas Motor Control Solutions
Due to rising concerns about global warming issues and demands to reduce power costs, power consumption reduction requirements (energy-saving requirements) for electronic equipment and devices are becoming more severe. It is said that power consumption by motors in home appliances makes up over half of the total power consumption of a common household. Thus, it can be said that reducing motor power consumption is the key to saving energy.
There are various methods of controlling a motor. Among them, the best control method for reducing power consumption is inverter control. Although inverter control demonstrates a tremendous ability to achieve energy savings, there are more than a few challenges associated with its implementation. The difficulty of carrying out the inverter control itself, the complicated hardware, and high cost are the typical challenges. Renesas has developed and provides solutions that help overcome such challenges.
