STEPPING MOTORS DRIVING CIRCUIT
■This method performs constant excitation of one phase only. The input is small and little temperature increase occurs, so a small power supply is sufficient.The attenuation vibration for each step, however, is large, so hunting can occur easily.
●phase exciting method
■This method performs constant exciting of two phases,and one phase is always exciting during phase switch-over. This results in braking effects during operation,and starting torque is always applied, so hunting decreases and the self starting frequency can be increased. The input is twice that of the 1 phase exciting method.
●1-2 phase exciting method
■This method alternately performs the 1 phase excitation method and the 2 phases excitation method,with the angle deviation being half that of the 1 phase excitation method and the 2 phases excitation method.The response frequency is approximately double.
