Texas Instruments Inc. has recently unveiled its new InstaSPIN-MOTION motor control solution. TI's latest offering 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 the company's InstaSPIN-FOC motor control solution, InstaSPIN-MOTION is uniquely designed to optimise 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 optimised sensorless motor control.

The InstaSPIN-FOC solution, which was announced earlier this year, takes advantage of the FAST 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.

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 32bit C2000 Piccolo microcontrollers (MCUs), InstaSPIN-MOTION integrates SpinTAC components from LineStream Technologies, featuring optimised 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 is available today on the production-ready, 90MHz, 32bit 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). If designers have a previously purchased a TI motor control development kit, they can order the modular InstaSPIN-MOTION-enabled Piccolo controlCARD for $99 (TMDSCNCD28069MISO).
