TI InstaSPIN™ Motor Control Solutions

Breakthrough motor control technology is here!
With premium control in all three phase variable speed, variable load applications

The motor ID and auto tuning solution in all variable-speed, variable-load motor applications

TI 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, sensorless, synchronous or asynchronous motor control system in just minutes.

This new technology removes the need for a mechanical motor rotor sensor to reduce system costs and improve operation using TI's new software encoder (sensorless observer) software algorithm, FAST™ (flux, angle, speed and torque), embedded in the read-only-memory (ROM) of Piccolo devices. This enables premium solutions that improve motor efficiency, performance and reliability in all variable-speed and load-motor applications.

Field Control

Field Weakening
  • Reduction of produced magnetic field of the motor
  • Allows for the rotor to obtain higher speeds than designed
  • Resulting loss of torque production
  • Needed for most efficient systems where high speeds are only needed for relatively short period of times
  • Enables optimum sizing of motor
Field Boosting
  • Increased magnetic field of the motor
  • Higher torque than designed
  • Needed for high starting torque applications
  • Enables optimum sizing of motor
Examples in the MotorWare™ software
  • Automatic and manual field weakening
  • Manual field boosting
