Many friends are not very familiar with the structure of brushless motors, and do not know how to start in the selection, in fact, the choice is not so difficult to master the main parameters of a few good, how specific?

Brushless DC motor selection of the main parameters.

Бесщеточный двигатель постоянного тока BLDC

Brushless DC motor torque size, look at the load torque, friction and the size of the rotational inertia, add up, there are some other factors, such as air gap and air resistance, etc.

2. Brushless DC motor square mode torque, there are also many parameters to determine, such as the size of the load torque, rotational inertia, upper limit torque, acceleration and deceleration, as well as the running time, etc., almost the actual continuous output torque size.

Brushless DC motor speed: according to the speed trapezoidal curve to see the motor speed requirements, in practice, for the required speed, generally retain almost 10% margin can be.

Щеточный/бесщеточный двигатель

The above points are the main parameters that need to be referred to when selecting brushless DC motors, master these basic related knowledge to ensure that the choice of motor for their own, to meet the needs of production.
