1. A method for determining motor capability, the method comprising:
determining, for a motor, a voltage constraint based on a d-axis voltage component associated with the motor and a q-axis voltage component associated with the motor;
determining, for the motor, a supply current constraint and a regenerative current constraint based on the d-axis voltage component associated with the motor, the q-axis voltage component associated with the motor, a d-axis current component associated with the d-axis voltage component associated with the motor, a q-axis current component associated with the q-axis voltage component associated with the motor, a supply voltage associated with motor, a supply current associated with the supply voltage associated with the motor, and an electrical resistance associated with the motor;
determining, for the motor, a motor current constraint based on the d-axis current component associated with the d-axis voltage component associated with the motor, the q-axis current component associated with the q-axis voltage component associated with the motor, and a motor current associated with the motor;
determining, for the motor, a first operating torque based on the voltage constraint, the supply current constraint, the regenerative current constraint, and the motor current constraint; and
at least one of selectively controlling the motor based on the first operating torque and generating information associated with the first operating torque.
