The invention discloses a milk foam machine directly driven by a motor, comprising a cup cover, a cup body, an inner cup, a stirrer, a control panel, an electric heating tube, a motor and a power supply base. The milk foam machine adopts a sleeved structure that an upper piece and a lower piece of an electric connector are respectively arranged below the cup bottom and on the power supply base; and after the upper piece is sleeved with the lower piece, an external power supply in the power supply base is connected with a circuit below the cup to supply power for the electric heating tube and the motor. An aluminum sheet is compounded on the electric heating tube; the motor is arranged below the cup through a motor fixed piece; a driving shaft of the motor passes through the cup bottom from the eccentric position and extends into a container; a stirrer for stirring or foaming is sleeved at the shaft end; a sealing ring with more than two rings of flange rings is arranged between the driving shaft and a shaft hole; the flange ring of an inner ring is protruded into a high lug boss for sealing the shaft hole and the shaft; and the flange ring of an outer ring is used for sealing the surface space between the cup bottom and the fixed sheet. The invention has the advantages of favorable sealing performance, simple structure, favorable foaming effect and stable heating. The milk foam machine is applicable for heating or not heating and foaming or only heating liquid state milk.
