Enhancing Motor Efficiency

A motor converts electrical energy into mechanical energy. A constant goal in motor control, drive, and design is to reduce energy loss and improve system efficiency during this conversion. With the global consensus on carbon emissions and environmental initiatives, the industry requires industrial motors and drives to achieve higher efficiency, lower costs, and greater integration, while also supporting new technologies and improving safety and reliability.

Motor control technology plays a significant role in improving the efficiency of motor systems. By adopting semiconductors with higher performance and integration, powerful and secure microcontrollers, and smarter sensors, combined with optimized software algorithms, it is possible to increase efficiency and reduce losses.

Intelligent Motor Control

Motor intelligence is a key component of smart industry. It can be realized in two main ways. First, by expanding the sensory range with additional sensors, such as vibration sensors, to monitor the motor's operating status. This allows for predictive maintenance or automated repairs before a failure occurs. Second, by using MCUs optimized for motor control that include a rich set of peripherals like high-speed ADCs, gate drivers, power modules, and motor control PWMs. On the software side, advanced AI algorithms can be incorporated for tasks such as processing environmental data and identifying the motor's own operating parameters.
