Higher Performance; Higher Efficiency Pump Motor Control
Pump controls using IRís iMOTION Integrated Design Platform have low-loss, low EMI space vector pulse width modulation and
high efficiency sinusoidal current control for quiet operation and higher efficiency. The modular approach eliminates software
programming, increasing efficiency and simplifying design. In addition, the single shunt current sensorless control does not
require voltage feedback sensing and increases reliability.
- Sinusoidal current control for quiet operation and higher efficiency
- Single current-shunt, sensorless control eliminates voltage sensing and increasing reliability
- Graphical algorithm editor eliminates coding
- Low loss; low EMI pulse width modulator
The iMOTION mixed-signal control IC implements a sensorless FOC algorithm in
hardware eliminating the need for software development. The sensorless algorithm
detects the rotor position based on the motor current measurement only, while the control
hardware allows motor winding currents to be measured without expensive isolation circuits.
