AC servomotor / synchronous / compact

New motor technologies help in producing enhanced dynamic motors with lower inertia. Almost all motor developments strive to achieve extra torque with a compact design along without reducing the size of the loads. In fact the motors are expected to carry higher amount of loads.

The motor design requires the torque to be calculated which helps to measure the mass inertia ratio from the quotient of reduced load moment of inertia and rotor moment of inertia of the motor.

This mass inertia ratio should be limited to 5:1 and in case of more than 10:1 ratios, the motor needs to be redesigned. Calculation the external inertia is made by the CYMEX design software and the mass inertia ratio is automatically taken after motor selection.
