Key Points
• Motor control requires tailored approaches
because of varying performance, efficiency, and
reliability needs across AC, brushed DC, BLDC, and
stepper motors.
• AC motors benefit from inverter-fed systems that
enable full speed control, improving efficiency by
eliminating mechanical converters.
• Though BLDC motors excel in longevity and
efficiency, they require complex electronic
commutation for sensorless control at low speeds.
• While traditional open-loop stepper motor control
often sacrifices energy efficiency and reliability
by not using any feedback, advanced stepper
motor drivers use motor back-EMF to provide both
efficiency and reliability by adding sensitive load
detection.
• Analog Devices offers precise current and position
sensing solutions, integrated motor drives, and
advanced algorithms to enhance motor efficiency
and simplify control systems.
