In this paper,a novel method of detecting rotor initial position of the PM BLDC motor based on inductance method is studied.

This paper analyzes the method used by Guangzhou Pumped Storage Power Station to detect the rotor initial position through the control logic of the static frequency convertor(SCF), pointing out that the bug in the method is to depend on the exterior circuit.

In this paper,a novel method of detecting rotor initial position of the PM brushless DC motor based on inductance method was studied.

The estimation accuracy of the initial rotor position for a permanent-magnet synchronous motor(PMSM) directly determines whether the motor could be started-up successfully or not, the operation behavior would be better or worse and the high performance control strategy could be realized or not.

A novel initial rotor position estimate method is proposed on the surface mounted permanent magnet synchronous motor(PMSM), which is based on the PMSM de-coupled model analysis.

Checking method of initial position for surface-mounted permanent magnet linear synchronous motor;

The initial position and velocity of pulverized coal at oxygen coal lance outlet has been proposed,thus injection of pulverized coal in the blast furnace can be simulated.

The inaccurate measurement of initial position of motor rotor when the motor starts is a problem existing in a servo system applying increment photo-electricity pulse coder.
