This introduction provides a comprehensive overview of the MSK076C-0300-NN-M1-UP0-NNNN motor, highlighting its key features, application scenarios, and technical parameters.

Stepper motors generally do not have overload capability. AC servo motors have strong overload capability.

Take Panasonic AC servo system for example, it has the capability of speed overload and torque overload.

Its maximum torque is three times the rated torque, which can be used to overcome the inertial torque of the

load at the moment of startup. Stepper motors, because they do not have this overload capability, often need to

select a motor with a larger torque in order to overcome this inertial torque when selecting a model, but the machine

does not need such a large torque during normal operation, resulting in torque waste.

Five, different running performance

The control of the stepping motor is open-loop control, and it is easy to appear stepping loss or stall when

the starting frequency is too high or the load is too large, and it is easy to appear overshoot when the speed is

too high at stop, so in order to ensure its control accuracy, the acceleration and deceleration problems should

be handled well. The AC servo drive system is a closed-loop control, and the drive can directly sample the feedback signal

of the motor encoder, and the internal composition of the position loop and the speed loop, generally will not appear stepping

motor stepping loss or overshoot, and the control performance is more reliable.
