About the brushless dc motor controller believe everyone will know, because it in the application of life is becoming very popular. Brushless dc motor controller in the main controller, which is the main use of the equipment control velocity components. And the realization of the controller to control the speed is benefited from the adjustment of the spring: 1, disconnect the power supply, open the box machine, out of the box cover, remove the lid. 2, use hex wrench to adjust each tension spring screws, brushless dc motor controller is the controller in the rod into the runtime achieve the best results. 3, if the time jitter phenomenon in a bar, balance the tension of the spring is too large, repeat the above operation. 4, 7 brake power, press bring or ▼ button of the controller, the brushless dc motor controller controller running four to five times up and down 90 degrees, such as pole time jitter phenomenon in a bar, that balance spring tension is not enough, the brushless dc motor controller controller running to the vertical state. 5, if the lever, the brushless dc motor controller is the controller's operation and brushless dc motor controller controller action, that balance tension spring tension is insufficient, adjusting the tension spring state or increase the tension spring, until the brushless dc motor controller controller running normally. Above is today we are going to introduce you to all of the contents of the brushless dc motor controller, if you have any questions, you can call contact us, we will provide you a detailed answer.
