Abstract：Aiming at the problem that the frequency control of motor speed control system runs unstably caused by the non-standard selection of the reactor，the basis and the way to form a complete set of additional reactor were studied. On the basis of practical experience and circuit analysis the significance and function of additional reactor were illustrated，the design and selection of DC reactor were presented according to the relevant circuit calculations of radio interference suppression reactor，alternating straight after rectifying power supply side AC reactor，improving the power factor of the gist. And the specific additional reactor design and the selection scheme

recommendation table were provided. Experimental results show that different models of inverter power supporting various types of reactor in the frequency control of motor speed control system can work stably and reliably，to improve the system power factor and reduce the temperature rise and noise of the motor.
