Parameters of Miniature Motors

The performance of various types of miniature special motors varies significantly, making it difficult to define their parameters uniformly. Generally speaking, motors used for driving machinery focus on power efficiency during operation and startup; those used as power sources prioritize output power, waveform, and stability; while control-oriented miniature motors emphasize static and dynamic characteristic parameters. The characteristic parameters of the first two types are similar to those of conventional motors.

Only control-oriented miniature motors have unique characteristic parameters.

Meaning of Miniature Motor Model Codes:

The first letter represents the shape: R for round, F for flat, S for rectangular.
The second letter indicates the brush type:
- E, A, U: Metal brush
- F, D: Metal fork-shaped brush
- C, K, H, S, T: Carbon brush
The third digit represents the rotor diameter.
The fourth digit indicates the magnet or housing length.
