4 Classification and model
4.1 Classification
Motors are classified into two types according to structure: split and assembled type.
4.2 Model
4.2.1 Model structure
The model of motors consists of four parts: the frame number, the product name code, the performance parameter code and the derivative code. The product name code is represented by uppercase Chinese Pinyin letters.
a) LW represents brushless DC torque motors (Al-Ni-Co);
b) LWX represents brushless DC torque motor (rare earth).
