In software design, rotor position capture, current sampling, the calculation of speed had been completed.

Next, an initial rotor position estimator is proposed to avoid the motor operating in an opposite rotating direction.

The state observer observes the precise load torque, rotor position and speed with only a low accuracy position sensor.

A rotor position detecting circuit is designed to obtain high-resolution rotor position signal from a low-resolution discrete Hall sensor.

The simulation results demonstrate the rotor position can be detected correctly, and the motor can start reliably.

This system can provide information of rotor position and speed by taking the place of the traditional sensor.

By detecting the back electromagnetic force (EMF), the rotor position of micro motor can be obtained.

The exact rotor position of the elevator traction motor is a pre-request for the driving control system.

Finally, the stator resistance effect of rotor position estimation in high frequency voltage signal injection is investigated.

A kind of variable speed control system of a brushless DC motor without a rotor position sensor was designed.

After that, a rotor position estimator is proposed. By detecting the back emf, a rotor position of the motor can be obtained.

The system of the rotor position using the eddy current measurement sensors.

Voltage waves are deduces on lower bridge arm PWM modulation and theory of rotor position detection based on EMF is introduced.

This paper presents an approach of rotor position estimation for switched reluctance motor based on support vector machine (SVM).

Rotor position sensor tracking linked with the motor shaft.

Directly take the Permanent E. M. F from the model of PMSM to calculate the rotor position and speed So it is simple and transpicuous.

An approach of detecting the rotor position for Switched Reluctance Motors (SRM) based on BP neural network is presented.

In sensorlees control aspect, the key issue lies in the accuracy of estimated rotor position and speed.

Rotor position feedback is required in some form and traditionally this is done with a rotor mounted sensor.

A way to measure the rotor position of permanent magnet synchronous motor (PMSM) was introduced.

CPLD is employed to deal with the brushless DC motor's rotor position signal in order to realize.

A new method was proposed to identify rotor position based on motor saliency effect.
