The invention provides a three-phase induction motor transient temperature rise calculation model and a measuring calculation method. Users often hope that one continuous duty motor can drive heavier loads to work for a short time to improve the service efficiency of the motor, but at the moment, the users generally have difficulty in determining whether normal start of the motor can be guaranteed under heavier loads and whether the working hours of safe operation of the motor can be maintained or determining the conditions of the loads which can be driven by the motor in different working hours. The three-phase induction motor transient temperature rise calculation model comprises a shell and a PC (personal computer) and is characterized in that a transient temperature rise rotor network equivalent module, a transient temperature rise stator network equivalent module and outgoing lines of measurement nodes are respectively installed in the shell (9); the outgoing lines of the measurement nodes converge and are connected on a terminal board (4); the terminal board is connected with the PC (5). The three-phase induction motor transient temperature rise calculation model is applied to the measuring calculation method.
