Technical solutions are described for controlling a brushed direct current (DC) motor, including: determining, based on one of a motor current command or an actual motor current, a brush voltage drop across a set of brushes of the brushed DC motor; determining, based on the brush voltage drop, at least one of: a first torque limit based on a supply current value not exceeding a supply current limit, and a second torque limit based on a controller supply voltage value not exceeding a maximum available voltage; determining a final torque limit based on the at least one of the first torque limit and the second torque limit; determining a limited torque command based on a torque command and not to exceed the final torque limit; determining a voltage command based on the limited torque command; and applying a DC voltage to the brushed DC motor based on the voltage command.
