Dc servomotor driving device
专利汇可以提供Dc servomotor driving device专利检索，专利查询，专利分析的服务。并且PURPOSE:To prevent resonance generation without delaying the control system response by a method wherein a ripple reducing reactor is serially connected with a motor and along therewith an LC serial resonance filter adjusted to the mechanical system frequency is connected in parallel with the motor. CONSTITUTION:When controlling a DC servomotor 6 with a PWM control, device, along with serially connecting a ripple reducing reactor 8 with a motor 6 an LC serial resonance filter consisting of a condensor 9 and a reactor 10 is connected in parallel with the motor 6. The resonance frequency of said LC serial resonance filter is equally set to the mechanical resonance frequency of charge 7 and only the resonance frequency component contained in the driving power source is made to bypass. Said constitution enables to make the reactor 8 small thus preventing the mechanical system resonance generation without delaying the control system response.，下面是Dc servomotor driving device专利的具体信息内容。
