The invention discloses a device and method for carrying out hovering control on a variable frequency driven load non-position encoder. The device comprises a speed/hovering linkage control module and a rotor field oriented vector control module, wherein the speed/hovering linkage control module outputs a given torque signal to a current control link, and a frequency signal of a rotor is output to the speed/hovering linkage control module in a frequency control link; in the current control link, according to the given torque signal output by the speed/hovering linkage control module and a rotor flux angle signal output in the frequency control link, an exciting voltage and a torque voltage are output to a pulse modulation link through calculation; and in the pulse modulation link, according to the exciting voltage and torque voltage output in the current control link and the rotor flux angle signal output in the frequency control link, a modulating pulse signal is output to the outside. According to the invention, the purposes of achieving an effect of long-time hovering and realizing the no-impact switching between speed control and hovering control under the condition of variable frequency driven lifting load non-position encoders are achieved.
