Brushless dc motor controller when use if they are not used in strict accordance with the instructions, it is not safe, so we set up protection measures in production, small make up for the next everybody simple introduction: controller for brushless dc motor drives have protective measures, even when the load is too large or improper use will cause large current and will power transistor burn down. In order to protect the damage due to current exceeds specifications drive, often to increase the resistance of power transistor current or add current sensor as a protection. Second when the motor controller workload big, in the stop is rotated by the motor controller side back to drive energy and overvoltage will endanger the drive, it can cooperate with overvoltage protection circuit with energy dissipation circuit to control retrogradation. There are other hall -Sensor is normal or not judge may also affect the correctness of the PWM control, it can be controlled by the department and timely warning. About protection of brushless dc motor controller is said to here, my company at reasonable prices, quality service, efficient service to win the support and recognition of users. On the basis of many years of experience and strong solid, if necessary please contact, we will serve you wholeheartedly. Small make up: Sara
