This introduction provides a comprehensive overview of the MSK050C-0300-NN-M1-UG1-NNNN motor, highlighting its key features, application scenarios, and technical parameters.

Servomotors need more space due to the requirements of absolute encoders. The lower pole count allows it to produce higher torque at higher speeds.

Stepper motors can operate in an open loop without an encoder, making them more compact.

Stop accuracy

For positioning applications, one of the key requirements that we must meet is the accuracy of the motor”s stop. Both stepper and servo motors can stop accurately.

The stop accuracy of a stepping motor depends on the quality of the winding (electrical) and the tooth structure (mechanical), while the accuracy

of a servo motor depends on the assembly accuracy, the encoder resolution andalgorithm.

Remember that the air gap between the rotor and stator is very thin, and the only friction is from its ball bearings. Frictional torque or gravity

load will cause a deviation in the actual stopped position, so there is a little error when you move from one position to another.

The errors that occur when we plot one full rotation of the motor are shown in the figure below.
