For brushless dc motor controller of some relevant knowledge we already know, but for its how to load test of the brushless dc motor controller is new, only to learn more, will be more helpful when using, the following will make a detailed introduction for you, please read. Brushless dc motor controller under the rated speed, according to its rated torque of 25%, 50%, 75%, 100%, 110%, 125% load tests are carried out step by step. Load experiment, record every 10 minutes a time, the oil temperature, rotational speed and torque. For bidirectional work or did not indicate the direction of rotation of brushless dc motor controller should be positive and negative respectively to test; For the work of one-way brushless dc motor controller can be single to experiment, its direction of rotation must be the same as the direction of the work. In the thermal power load test of the brushless dc motor controller in the oil pool temperature stability constant two hours. Its temperature should comply with the requirements, the seal, heads, heads are not allowed to have oil leakage. For the brushless dc motor controller knowledge understanding, hope to help everyone, so in the later use believe that will be more favorable to us.
