The brushless DC motor is composed of a motor body and a driver, and is a typical electromechanical product. Which parameters should be referred to when selecting a brushless DC motor?
1. Larger torque: Brushless DC motor can be obtained by adding load torque, rotational inertia and friction. In addition, there are some additional factors that affect the larger torque, such as the resistance of the air gap.
2. Square mode torque: It can be approximated as the continuous output torque required by the actual application, which is determined by many factors: larger torque, load torque, acceleration and deceleration, and running time.
3. Rotation speed: This is the speed required by the application. The speed demand of the motor can be determined according to the speed trapezoidal curve of the DC brushless motor. Usually, a margin of 10% should be left in the calculation.
The above are the main parameters that need to be referred to for the brushless DC motor type. You must pay more attention to the selection to prevent future troubles.
