A method for distributing electrical power to electric motors in an electric powertrain, in which the electric motors are electrically connected to a shared power supply, includes receiving input signals via a supervisory controller. The input signals include a total torque request of the electric powertrain and electrical limits of the power supply. The method includes determining an open-loop torque command for each respective motor in response to the input signals. In response to the total torque request and the power supply limits, the controller also determines maximum and minimum power limits of motor, with the maximum and minimum power limits including a calibrated power reserve for executing a predetermined torque operation. The method includes transmitting the open-loop torque command and the power limits to a respective motor control processor of each motor to thereby control the torque operation.
