摘要： Examples include a method for determining a static load torque at standstill applied to a salient pole synchronous motor. The method comprises fixing a first non-zero torque-producing current component and controlling motor speed using a speed loop regulation of a first regulated component to reach a first zero motor speed steady state corresponding to the fixed first non-zero current component, the motor being subjected to the specific static load torque. The method further comprises controlling motor speed using a speed loop regulation of a second regulated component to reach a second zero motor speed steady state corresponding to a fixed second non-zero torque-producing current component, the motor being subjected to the specific static load torque, the first non-zero current component and the second non-zero current component corresponding to different values. The load torque is estimated as a function of components of the first and second zero motor speed steady states.

摘要： Embodiments of this application provide a heating control method and apparatus, an oil pump, and a heat exchange system. The method includes: in a cold state, injecting a heating current into an oil pump motor, where when the oil pump motor is not started, a torque that the heating current is capable of generating is zero, and after the oil pump motor is started, heating power of the heating current is greater than heating power of an energy-saving current, where the energy-saving current is a current capable of enabling a first motor to reach a target operating condition when oil temperature is greater than a preset temperature threshold.
