This introduction provides a comprehensive overview of the MDD112B-N-030-N2L-130PAO motor, highlighting its key features, application scenarios, and technical parameters.

A stepper motor is an actuator that converts electrical pulses into angular displacement.

Simply put, when a stepper driver receives a pulse signal, it drives the stepper motor to rotate

a fixed angle (and step angle) in the set direction.
You can control the angular displacement by controlling the number of pulses to achieve accurate

positioning; At the same time, you can control the speed and acceleration of the motor rotation by

controlling the pulse frequency, thus achieving the purpose of speed regulation.
There are three types of stepper motors: permanent magnet (PM), reactive (VR), and hybrid (HB)
Permanent magnet stepping is generally two-phase, with small torque and volume, and a stepping

angle of generally 7.5 degrees or 15 degrees;
Reactive stepping is generally three-phase and can achieve high torque output. The stepping angle

is generally 1.5 degrees, but the noise and vibration are both significant. In developed countries such as

Europe and America, it was already eliminated in the 1980s;
Hybrid stepping refers to the combination of the advantages of permanent magnet and reactive methods.

It is divided into two phases and five phases: the two-phase step angle is generally 1.8 degrees, while the five

phase step angle is generally 0.72 degrees. This type of stepper motor is most widely used.
