The difference between stepping motors
Hybrid stepper motor: the step motor is divided into three types: permanent magnetic (PM), reactive (VR) and hybrid (HB). The permanent magnet step is generally two phases, the torque and volume are small, the step Angle is usually 7.5 degrees or 1.5 degrees. The reaction type step is generally three-phase, can realize the big torque output, the step Angle usually is 1.5 degrees, but the noise and vibration are very large. Developed countries such as the United States and Europe were eliminated in the 1980s. Hybrid step refers to the advantage of mixing permanent magnet and reactive type. It is divided into two phase, three-phase and five phase: two phase stepper Angle of 1.8 degrees commonly and five phase stepping Angle of 0.72 degrees commonly, hybrid stepping motor as the increase of the number of phase (several) winding the power supply, the stepping Angle decreases, and improve the precision and the application of the stepper motor is more extensive.
Take a look at this step into the motor's encyclopedic card, and you don't know how to do it before. 42 and 56 (the flange dimensions are generally 56.4 mm, people are used to saying 57 motor) is the size of the flange disk of the step motor.
Stepper motor is installed flange type specification, 42 refers to the stepper motor, 42 mmx42mm 56 is similar, the motor should be a hybrid stepper motor, stepper motor is the biggest difference between torsion and interval Angle, determine its general motors fuselage length and diameter of torsion, step away from the Angle of provided by the manufacturer, at present most is given priority to with the hybrid stepping motor, general interval Angle is 1.8 1.2 0.9 degrees, 0.72 degrees,
