Abstract
A variable-speed integrated machine and a wellsite apparatus are disclosed. The variable-speed integrated machine includes: a driving device which includes an electric motor and a housing; an inversion device which is disposed on the housing and electrically connected with the electric motor; an inversion heat dissipating device which is disposed at one side of the inversion device away from the housing and configured to perform heat dissipation on the inversion device in a liquid-cooling heat dissipating way; and a driving heat dissipating device, at least one portion of the driving heat dissipating device being disposed on the housing and configured to perform heat dissipation on the driving device in at least one selected from the group of a liquid-cooling heat dissipating way and an air-cooling heat dissipating way, the inversion device and at least one portion of the driving heat dissipating device are disposed on a same side of the housing.
