Motor Control: Why ADI... Why Now?

We can help you design motor control systems that are safer, more productive, and optimized for energy efficency.

Analog Devices knows that more stringent energy regulations worldwide demand smarter and highly efficient motor control systems. We give design engineers a system-level view with consideration of the critical isolation architecture, allowing systems to achieve the greatest level of efficiency while improving accuracy and reliability.

A System View of Energy Efficiency


With electric motors and their drive systems consuming up to 46% of the world’s electricity, regulatory agencies across the industrial countries have introduced minimum energy performance standards (MEPS), resulting in widespread demand for high-efficient motor drive systems.

Motor Drive Ecosystem for Optimizing Energy Efficiency

Automated machines and processes in a modern factory have multiple control layers that determine the efficiency of the motors and the overall production process. By taking a system view, there is a new capacity to optimize the operation of machines and processes and add new levels of efficiency in energy and productivity.


Efficient Torque Production to Improve Motor Efficiency

There are multiple control layers that determine the efficiency of the motors and the overall production process. The first layer adjusts the power inverter switching sequence to control the motor voltage and current, as well as maximize torque production efficiency. Motor efficiency is a function of the torque produced per amp supplied and motor construction and particularly the rotor field structure. Drive manufacturers now supply standard drive boxes that can be configured for a variety of motor models and types and include algorithms to optimize motor efficiency and monitor the drive health.  In addition, a growing trend is to connect the drives to the factory network to further improve efficiency by coordinating the operation of multiple drives.

Precision Isolation and Communication for Efficient Motion Control

The position and speed controller layer provides execution comments to operate automated machine efficiently. The communication and systems layer is growing in importance as multiple motors are now synchronized over high speed data networks, also connected to the factory network. The combination of precision in motion and communication timing enables shorter machine production cycles and reduces the amount of energy consumed to manufacture each part.

Modeling Tools Enable Rapid Customization to Optimize Energy Efficiency

Automated machines are complex interconnected systems requiring the support of multi-disciplinary engineering teams often working in different companies. Modeling tools support complete system models, including state control, motion algorithm, motor and machine load. While the complete design process cannot be fully automated, the number of prototype builds can be significantly reduced. Drive companies can thus rapidly deploy new control functions for specific applications to optimize energy efficiency and automation productivity.
