Improved Motion and Efficiency for Advanced Motor Control Designs

June 28, 2013
Texas Instruments Inc.'s InstaSPIN-MOTION is a comprehensive torque-, speed- and motion- control software solution that delivers robust system performance at the highest efficiency for motor applications that operate in various motion state transitions.

 InstaSPIN-MOTION from Texas Instruments is a comprehensive torque-, speed- and motion- control software solution that delivers robust system performance at the highest efficiency for motor applications that operate in various motion state transitions. Built upon TI's InstaSPIN(tm)-FOC motor control solution, InstaSPIN-MOTION is uniquely designed to optimize complex motion sequences, reduce tuning to a single parameter and tracking desired trajectories with unmatched accuracy across operating ranges. It constitutes the easiest and most effective method for achieving optimized sensorless motor control.

TI's InstaSPIN-FOC takes advantage of the FAST(tm) premium software sensor for rotor flux measurement and provides motor identification, automatic current control tuning and sensorless feedback in a field-oriented control  (FOC) torque controller and speeds deployment of efficient, sensorless, variable load three-phase motor solutions.

InstaSPIN-MOTION further improves motor performance and development time. Adding additional motor control functionality, InstaSPIN-MOTION enables more expertise on chip. With the core algorithms embedded in the read-only-memory (ROM) on TI's 32-bit C2000(tm) Piccolo(tm) microcontrollers (MCUs), InstaSPIN-MOTION integrates SpinTAC(tm) components from LineStream Technologies, featuring optimized motion profiling, single-parameter tuning and a disturbance-rejecting controller, which speeds development and increases performance across changing speeds and loads.  InstaSPIN-MOTION can be used with sensored feedback or with the included sensorless InstaSPIN-FOC solution.

InstaSPIN-MOTION's SpinTAC(tm) components include:

  • IDENTIFY: Ensure optimum tracking and disturbance rejection, working with the real inertia of the system.
  • CONTROL: Minimize effort and reduce complexity with single coefficient tuning. Rapidly test and tune velocity control from soft to stiff response, defining a controller gain that typically works across the entire variable speed and load range of an application.  Actively estimate and cancel system disturbances in real time, providing maximum performance.
  • MOVE: Produce an automatically optimized motion profile based on start velocity, target velocity and system limitations for acceleration, jerk and motion trajectory type.
  • PLAN: Quickly build various states of motion (speed A to speed B) and tie them together with state-based logic.

Develop and evaluate quickly using the new motor control software infrastructure, MotorWare. Take advantage of modules, drivers, system examples and documentation representing the latest in C object-oriented and API-based coding techniques.

InstaSPIN-MOTION is available today on the production-ready, 90 MHz, 32-bit floating point Piccolo F2806xM microcontrollers starting at $10.22 USD per 10 Ku.  Designers can begin their latest InstaSPIN-MOTION motor designs with a low-voltage, low-current motor control kit for $299 (DRV8312-69M-KIT, low-voltage, high-current motor control kit for $299 (DRV8301-69M-KIT or high-voltage motor control kit for $699 (TMDSHVMTRINSPIN.
