What should I pay attention to when purchasing a brushless motor?
Brushless motors are widely used. It is usually used on equipment with high control requirements and high speed, such as model aircraft instruments and meters that strictly control the motor speed and achieve high speed. So what should we pay attention to when purchasing a brushless motor?
According to the requirements of power insulation, ensure the normal operation of the driver.
2. Pay attention to the current of the motor
Let's choose the peak current of the driver. The method for selecting the peak current is that, given the rated input current Ir (A) of the motor, the peak current Ip (A)=2xIr. Otherwise, there is no certain engineering margin for the output current of the driver during use. If the rated output power or output power Pr (W) and driving voltage Vr (V) of the brushless motor are known, the peak current Ip (A) is ≥ 4xPr/Vr.
3. Pay attention to the operating temperature of the motor
We can also set the motor according to the parameters, but we need to set the appropriate parameters for different motors, and of course, we also need to consider the application range of temperature. The wider the temperature, the higher the price will be.
4. Pay attention to the voltage of the motor
The voltage is provided by an electronic switch circuit controlled by the output of the position sensor. To choose a brushless motor product, the first step is to select the correct voltage, and the rated voltage should be selected according to the driving voltage parameters required by the customer. Please note that the voltage used during the no-load and full load processes should not exceed the range specified by the driver.
The above are the things we need to pay attention to when purchasing a brushless motor. We hope that the above suggestions can be applied in practice and have a substantial impact. For more related questions, please follow our website.
