| | | MCS synchronous servo motors have been developed in particular for dynamic drive tasks and therefore feature very high standstill and maximum torques. These optimised characteristics enable a smaller motorto be selected for many applications than if the motor was dimensioned in accordance with the rated data. You can find a brief overview of the most important data and relationships for dimensioning a servo motor below: Gearbox ratio For optimum dynamics | | |

| | | The thermal design of the motor takes the effective torque and the average speed into account. In the case of short load cycle steps and cycle times < 1 min, the following applies: Effective torque Mean speed | | |

| | | T = 2/At; | | |
| | | |
| | | If the thermally effective working point nm,Meff is below the characteristic curve for continuous operation or the following relationship is true Meff<M0+(MN-M0)^L and all working points Mz,nz are below the torque limit line, then the thermal design of the motor is sound. | | |
| | | |
| | | Illustration of correct thermal motor design: Lines Meff and nm intersect below the characteristic for continuous operation, and all working points Mz,nz are below the torque limit line (dependent on motor and servo controller selected). | | |
