Trinamic – Single Axis BLDC Modules

ADI Trinamic’s single-axis servo modules for BLDC motors are flexible, cost-effective solutions to decentralized, coordinated control of BLDC or BLAC motors. Equipped with field-oriented control using encoder signals, the servo controller module brings precise and dynamic positioning to your application while reducing overhead cost.

Ready for Connectivity
A motor drive system consists of several functional building blocks. The motion controller receives commands over a selected interface, in a defined protocol. The commands are translated into signals for the motor control and driver part. For this transformation of digital information into perfect physical motion, ADI Trinamic™ products cover a wide range of interfaces and protocols.

FOC Servo Out of the Box
Field oriented control (FOC) is the most efficient way to drive motors. It transforms actual phase currents from stator-fixed to field-synchronous coordinate systems by using two mathematical transformations. The resulting coordinate system has only two dimensions (magnetic flux and torque), which are orthogonal components and can be visualized as a vector; hence FOC may sometimes be called vector control. FOC was originally developed for high end applications and has traditionally been difficult to implement. ADI Trinamic™ technology offers FOC as an easy-to-use hardware building block.

Real-Time Feedback and Control
Under common conditions, the position of a stepper motor is deterministic and predictable, but what about when the motor does not behave as expected? Many devices demand real-world, real-time feedback from the motor for added safety and monitoring purposes. Closed-loop operation of motors can furthermore increase the efficiency and overall performance of your application, for example by reducing the current when the motor is on standby and increasing the current under load conditions. As such, closed-loop control increases the system’s control reliability and flexibility.
