One popular sensorless ... motor torque and flux. The other control functions include the rotor-angle estimation, field weakening for high-speed operation and the phase-current reconstruction block.

One emerging control technique is field-oriented control (FOC). FOC is a sensorless method that reads the trapezoidal-shaped feedback voltages from the motor ... a detailed block diagram of ...

For an EV powertrain to drive smoothly, the control scheme should be such that the motor is able to operate over a wide range of speed and produce ... We see in the diagram that this value is fed to ...

Its sensorless design saves the space and cost of a Hall sensor. The built-in closed loop speed control regulates and maintains the motor’s rotational speed during dynamic power supply fluctuations ...
