Motor characteristic values reported in the tables refer to Brake current consumption values refer to a rated voltage of operating condition and should be regarded with a tolerance continuous duty (S1), 50 Hz frequency, ambient temperature 230V AC single-phase. of ± 3dB. mad i 40 °C, altitude up to 1000 m. above sea level operating 3. table shows the sound pressure noise level, measured 4. The rated torque Tn (Nm) for motors can be calculated as condition. at one metre range from the motor according to the Acurve follow: Tn (Nm) = 9,55 x Pn (W) 2. The expressed brake torque is the max admissible one. (ISO 1680). The shown noise levels refer to motor no-load rpm |
