TI InstaSPIN™ Motor Control Solutions

TI InstaSPIN sensorless, three-phase motor solutions makes designing motor control applications easier whether you have a simple application or a complex design. TI's InstaSPIN-enabled MCUs provide expertise to designers of sensorless (velocity and torque) or sensored (position, velocity and torque) motor control applications and are enabled by a special library on select Piccolo™ microcontrollers. 

InstaSPIN-FOC

Sensorless (FAST software encoder) torque or velocity control for any three-phase motor

  • Motor parameter identification
  • Applications: compressors, pumps, and AC drives

InstaSPIN-MOTION

Sensored position or velocity motion control for any three-phase motor

  • Single variable position/velocity control tuning
  • Applications: robotics, CNC, and servos

Tools & software

InstaSPIN solutions are offered on a variety of evaluation modules in order to make it easier to evaluate and develop

  • GUIs for evaluation and development
  • Software with documentation and support

InstaSPIN-FOC

InstaSPIN-FOC (field-oriented-control) technology enables designers — even those with limited motor control experience — to identify, tune and fully control any type of three-phase, variable speed motor control system in just minutes.

InsatSPIN-FOC features

InstaSPIN-FOC features

Motor identification

  • No datasheet required
  • One time parameter identification based on simple motor nameplate data (max voltage, current)
  • Optional Rs on-line feature can track resistance changes and provide compensation during operation

FAST software encoder

Universal three-phase motor software encoder

  • Rotor flux observer / estimator
  • Requires no tuning
  • Stable, reliable, and recoverable feedback to control system
  • Unique, high quality feedback signals for use in control systems

Control loop tuning

  • FOC current controllers automatically tuned for stable operation
  • User tuned speed controller
  • PowerWarp technology saves energy under partial loads

System flexibility

  • Created for any three-phase motor system
  • Simple API interface
  • Full customization for expert users

Field control

  • Field weakening allows for the rotor to obtain higher speeds than designed and enables optimum sizing of motor
  • Field boosting increases the magnetic field of the motor and enables optimum sizing of the motor

Software architectures

The flexibility of the library allows for a variety of configurations including: 

  • Using the library only for feedback
  • Fully abstracted sensorless FOC torque or torque and speed loop with minor user control adjustments
  • Fully customizable control system 

InstaSPIN-MOTION

TI InstaSPIN-MOTION is powered by SpinTAC from LineStream Technologies.  InstaSPIN-MOTION is ideal for applications that require accurate speed and position control, minimal disturbance, and for applications that undergo multiple state transitions or experience dynamic changes. 

InstaSPIN-MOTION is a super-set solution, including all features and capabilities of InstaSPIN-FOC.

InstaSPIN-MOTION features

InstaSPIN-MOTION features

Identify inertia

  • Uses inertia to provide the most accurate system control across a wide range of inertia change
  • The SpinTAC intertia estimator automatically measures system inertia by spinning the motor and measuring feedback

Simple tuning

  • Single coefficient tuning to quickly test and tune your control from soft to stiff response
  • Reduce complexity and system tuning time in multi-variable PID based systems with single gain (bandwidth) that works across the entire variable speed, position and load range of an application
  • A single parameter tunes both position and speed

Disturbance rejection

  • SpinTAC controller automatically rejects disturbances caused by:
    • cycle transitions
    • changing loads
    • environmental disturbances
  • Maximize control and recover more quickly than a PI controller, with less oscillation, and minimal over/undershoot

Execute motion profiles

  • SpinTAC runs on the processor to create smooth configurable trajectories between two positions/speeds
  • The Motion Engine automatically generates the best curve to satisfy the user-entered jerk and acceleration constraints for each move

Plan trajectories

  • Quickly build various states of motion (point A to point B) and tie them together with state based logic (hold for time, wait for interrupt, move to state C or D based on logic, etc.) in minutes
  • Directly embed the trajectories into the C code on the microcontroller

Software architectures

Example projects are designed in a modular structure to demonstrate the flexibility of adding InstaSPIN-MOTION features to your application. Architectures include:

  • Sensorless speed control
  • Sensored speed control
  • Sensored position (servo) control
