Buying a stepper motor has the following main characteristics:
1 the stepper motor must be driven to operate, and the driving signal must be pulse signal. When there is no pulse, the stepper motor is stationary. If appropriate pulse signal is added, it will rotate at a certain Angle (known as step Angle).The speed of rotation is proportional to the frequency of the pulse.
2. The stepping Angle of the three-phase stepping motor is 7.5 degrees, and it needs 48 pulses to complete a circle of 360 degrees.
The 3 step motor has the superior characteristic of instant start and quick stop.
4 Changing the order of pulses can easily change the direction of rotation.
Therefore, at present, the printer, plotter, robot, and so on equipment all take the stepper motor as the power core.
