InstaSPIN™ Motor Control Solutions

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



Rotor FLUX

  • High quality Flux signal for more stable flux monitoring and field weakening and boosting applications

Rotor Flux ANGLE

  • Best rotor flux Angle estimation accuracy over widest speed range
  • Provides reliable angle tracking within one electrical cycle of rotation
  • With quality sense inputs can track at under 1 Hz frequency
  • Angle tracking is completely robust under dynamics and FAST recovers and re-locks after an over load stall event
  • Typical angle accuracy within +/-1 count of a 1024 mechanical encoder steady state
  • Angle estimate for induction machines is independent of rotor resistance

Rotor Flux SPEED

  • Mechanical and electrical rotor speed estimations (including slip for induction)
  • Without position derivative quantization seen in standard observers
  • Reduces phase lag in control systems
  • Best speed input into the control system

Shaft TORQUE

  • Accurate rotor shaft torque signal for load monitoring
  • Use in custom control systems for flow rate monitoring, unbalanced load detection, and motor health diagnostics

FAST™ Software Encoder

Universal 3-phase motor software encoder supports

  • Synchronous (BLDC, SPM, IPM)
  • Asynchronous (ACI) motors
  • Unique, high quality feedback signals for use in control systems

Performance

  • Stable estimations
  • Tracks below 1 Hz
  • Tracks through zero on speed reversals
  • Stable feedback to control system when rotor is at zero speed

Motor Parameters

  • Relies on fewer parameters than other observers
  • Off-line commissioning learns the needed electrical motor parameters
  • Optional on-line observer tracks parameter changes to insure estimation accuracy over time and temperature

Tuning

  • No tuning of the observer required
