Selection assistance for determining the brake series
To avoid iterative loops during selection and dimensioning, it is important to make a well‑suited preliminary selection of the brake series based on fundamental characteristics.
The following table shows the permitted servomotor and brake combinations:
| BK.. | BP.. | BR.. | BY.. | BY..C | BY..D | BZ.. | BZ..D | BZ..Z | BKB.. | |||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

Based on the functional principles described above and their respective strengths, the following perspective emerges for the brake portfolio of SEW‑EURODRIVE with regard to common requirements for characteristics:
CM.. | CMP.., CMPZ.. | CM3C.., ECM3C.., CM3P.. | DRC.. | CMSB.. | CM3G. | |||||
|---|---|---|---|---|---|---|---|---|---|---|
BR.. | BP.. | BK.. | BY.. | BK.. | BZ.. | BY.C | BP.. | BK.. | BKB.. | |
Compact length/low mass | -- | ++ | ++ | -- | + | 0 | - | 0 | 0 | ++ |
High cycle rate | - | 0 | ++ | - | ++ | - | - | 0 | ++ | ++ |
Low rotational clearance | 0 | 0 | ++ | 0 | ++ | 0 | 0 | 0 | ++ | ++ |

High safety requirements | 0 | - | --Permanent magnet brakes can remain open if the braking work W Insp is exceeded, even in the absence of voltage. This state must be taken into consideration in applications with high safety requirements. | ++ | --1) | ++ | 0 | - | --1) | --Permanent magnet brakes can remain open if the braking work W Insp is exceeded, even in the absence of voltage. This state must be taken into consideration in applications with high safety requirements. |
The individual distribution of the strengths of each series has a corresponding effect on the suitability for certain types of applications. The following table provides a basic overview:
CM.. | CMP.., CMPZ..
| CM3C.., ECM3C.. | DRC.. | CMSB.. | CM3G.. | |||||
|---|---|---|---|---|---|---|---|---|---|---|
BR.. | BP.. | BK.. | BY.. | BK.. | BZ.. | BY.C | BP.. | BK.. | BKB.. | |
