Work machine accessory motor load protection

A method comprising:

• driving a first group of one or more hydraulic accessories of a work machine with a first pump operatively connected to an electric motor;
• driving a second group of one or more hydraulic accessories of the work machine with a second pump motor operatively connected to the motor;
• estimating a torque of the second pump;
• estimating a total torque of the motor as a sum of a current operating torque of the motor and the estimate of the torque of the second pump;
• and
• on condition the total torque of the motor is greater than a threshold torque, lowering an operating torque of at least one of the first pump or the second pump.

A work machine comprising:

• a first hydraulic circuit including a first pump configured to drive a first group of one or more hydraulic accessories of the work machine;
• a second hydraulic circuit comprising a second pump configured to drive a second group of one or more hydraulic accessories of the work machine;
• a single electric motor operatively connected and configured to drive the first pump and the second pump;
• and
• a controller configured to:
• estimate a total torque of the motor;
• compare the total torque to a threshold torque;
• and
• on condition the total torque is greater than the threshold torque, lower an operating torque of at least one of the first pump or the second pump.
