Abstract

Currently the special algorithms are used to determinate an initial position of rotor angle of the permanent magnet synchronous drives. This is especially important for providing of smooth load at the electric drive starting, for example, for gearless elevator hoist drive. For this the position sensors are used in simple electrical drives, but system cost is increased. Paper describes a developed new algorithm, which determines an absolute angular position of rotor of the permanent magnet synchronous motor. Stator is magnetized by leakage currents of windings at applying the specific voltage pulses to the motor. This algorithm allows calculating absolute position of the rotor in practice. The main advantage of presented algorithm is a functioning without motor parameters. Simplicity and algorithm efficiency are confirmed by obtained experiment results by simulation for determination of initial position of rotor of the permanent magnet synchronous motor. Therefore, this method can be widely used by engineers of electrical industry.
