Abstract
Technical solutions are described for controlling a surface-mounted permanent magnet (SPM) motor. A method for controlling a surface-mounted permanent magnet (SPM) motor includes: determining a peak torque value; determining a limited torque command based on a torque command and which does not exceed the peak torque value; determining, based on the limited torque command, a voltage command; and commanding, based on the voltage command, an inverter to apply an output voltage to the SPM motor. Determining the peak torque value includes: determining a voltage angle of the output voltage relative to a q-axis; and calculating the peak torque value based on the voltage angle of the output voltage and based on an available voltage to an input of the inverter.
