8WS servo motors are available in various sizes (1, 2, 3, 4). These differ in dimensions (especially flange dimensions) and power data. The different sizes are distinguished by a number (c) in the model number. The larger this number, the larger the flange dimensions and power data of the respective motor.

A servo motor of type 8WSA32 with a nominal speed of 8,500 rpm was selected for an application. Protection class IP66/67 is required. The hybrid motor cable on the motor should be 3 m long.

The code (c) for the selected size (3 = ø 32 mm) is 3.

The code (d) for the selected length (2 = 20) is 2.

The code (ee) for the encoder system (SSI encoder, single-turn) is F0.

The code (nnn) for the selected nominal speed (8,500 rpm) is 085.

The code (ff) for the selected motor options (protection class IP66/67) is V4.

The code (gg) for the selected cable length (3.0 m) is LE.

The code (h) for the motor version (0) is 0.

The model number for the necessary motor is therefore 8WSA32.F0085V4LE-0.

A servo motor of type 8WSA43 with a nominal speed of 5,500 rpm was selected for an application. A hygienic design with protection class IP69K is required. The hybrid motor cable on the motor should be 0.5 m long.

The code (c) for the selected size (4 = ø 40 mm) is 4.

The code (d) for the selected length (3 = 30) is 3.

The code (ee) for the encoder system (SSI encoder, single-turn) is F0.

The code (nnn) for the selected nominal speed (5,500 rpm) is 055.

The code (ff) for the selected motor options (protection class IP69K) is V8.

The code (gg) for the selected cable length (0.5 m) is LB.

The code (h) for the motor version (0) is 0.

The model number for the necessary motor is therefore 8WSA43.F0055V8LB-0.
