Protection device of electric power steering device for e.g. motor vehicle limits current supply to motor based on limiting values determined based on thermal time constants of motor and control circuit
Protection device of electric power steering device for e.g. motor vehicle limits current supply to motor based on limiting values determined based on thermal time constants of motor and control circuit
A limiting value setting unit sets two current limiting values based on thermal time constants of a control circuit or an electric motor (1). The current supply to the motor is controlled based on the limiting values, to prevent overheating of the control circuit and motor.
