AI Technical Summary
In the existing technology, the discharge protection method of motor controller relies on time monitoring, which may cause the discharge resistor to carry a large current for a long time under abnormal operating conditions, resulting in overheating and damage, and the discharge protection performance is insufficient.
By setting discharge safety limits based on historical and current discharge data of the discharge resistor, the actual discharge status is monitored and compared in real time, triggering the motor controller to immediately stop the discharge operation under abnormal conditions, thus preventing the discharge resistor from overheating.
This improves the discharge protection performance of the motor controller during the discharge process, prevents the discharge resistor from overheating and being damaged, and ensures the operational reliability of the motor controller.
