ABSTRACT:
A method of generating pulses includes setting a cycle based on a frequency of reference clock, determining a total number of the pulses to be generated during the cycle, calculating the number of one or more first reference clocks used to determine a width of one or more first pulses, the number of one or more second reference clocks used to determine a width of one or more second pulses, a first pulse number for the first pulses and a second pulse number for the second pulses on the basis of the cycle and the total number of the pulses, and generating the first pulse number of the first pulse and the second pulse number of the second pulses during the cycle. A motor control system employs the above pulse generating method and a pulse generator using the method to improve accuracy of controllability of a motor by generating the total number of the pulses during a cycle, and decrease a manufacturing cost.
