There are two types of miniature three-phase brushless motors, the housing is made of aluminium alloy and there are two types inside, the A type is infinite, the KV value is about 260, and the B type is limited, the angle of rotation is about 210 degrees.

 

Weight of the B motor: approx. 34.5 grams

       As the B model motor is limited in position and has a rotation angle of approximately 210 degrees, we are unable to test its parameters, so please understand.
