Incremental encoder electronic commutation signal alignment method introduction

The incremental encoder with transponder signal UVW electronic transponder signal phase and rotor magnetic pole phase, or said electrical angle between the phase alignment method is as follows: 1, with a DC power supply to the motor's UV winding less than the rated current DC, U in, V out, the motor shaft directed to a balanced position; 2, with an oscilloscope to observe the encoder's U believe the number of signals and Z signals; 3, according to the operation and control of the According to the convenience of operation and control, adjust the relative position of the encoder shaft and the motor shaft, or the relative position of the encoder shell and the motor shell; 4, one side of the adjustment, while observing the encoder U believe the signal jump along, and the Z signal, until the Z signal is stable (Explanation: solid and stable; there is no change) in the high level, locking the encoder and the motor of the relative position of the relationship; 5, back and forth to twist the motor shaft, after the spreading of the hand, if the motor axis each time free return to the equilibrium position, the Z signal can be stabilized on the high level, then the alignment is valid. Remove the DC...
