Servo & stepper drives

Design high-bandwidth and high-precision closed-loop motor-control systems

Our single and multicore microcontrollers (MCUs) with integrated real-time motor-control peripherals, math accelerators, programmable real-time processors and configurable logic blocks enable:

• Low latency and high bandwidth chip-to-chip interfaces.
• Accurate fast position, speed and torque control.
• Parallel execution of control, communication and predictive maintenance algorithms.
• Less than 1-µs computing time for field-oriented or direct torque control to achieve high dynamic performance.
• Single-chip MCU with integrated industrial communication and real-time control peripherals remove the need for an external field-programmable gate array.

Design efficient, reliable and small-form-factor power stages with precise current sensing

Explore how our gallium nitride field-effect transistor (FET) power modules, isolated and nonisolated insulated-gate bipolar transistor and silicon-carbide FET gate drivers, and 100-V integrated three-phase smart gate drivers help you achieve high-efficient, high-performance and small-form-factor centralized and motor integrated power stages for input voltages such as 48 VDC or AC inputs as high as 690 VAC.

Our low-latency isolated and nonisolated current-, voltage- and temperature-sensing products with extended temperature ranges help you achieve precise and high-bandwidth current control and advanced motor diagnostics for predictive maintenance.

From multiprotocol Industrial Ethernet to Gigabit TSN

In smart factories, servo drives are used in conveyor belts, machines, tools and robots. These applications may require support from multiple real-time Ethernet protocols such as EtherCAT, Profinet Real Time/Isochronous Real Time, EtherNet/IP and, soon, gigabit Time-Sensitive Networking (TSN). Our Sitara™ microcontroller and microprocessors have multiprotocol capability built in, with additional resources for multiaxis motor control. 

Our Ethernet physical layers (PHYs) support a range of standard protocols, data rates and high electromagnetic compatibility immunity for implementation in harsh industrial environments. For closed systems such as robotics and machinery, 10-, 100- and 1-Gb single-pair Ethernet PHYs are available.
