Hybrid stepping motor is a mixture of permanent magnet and the advantages of reactive. It is divided into two and five phase: two phase stepper Angle generally to 1. 8 degrees and five phase stepping Angle generally is 0. 72 degrees. The application of the stepper motor is more extensive, and the stepping motor subdivided driving scheme is chosen. Stepper motor has a technical parameters: no-load start frequency, the stepper motor under no-load condition can normal boot pulse frequency, if the pulse frequency is higher than the value, the motor does not start properly, may be lost or blocked. In the load cases, start frequency should be lower. If you want to make the motor to achieve high-speed rotation, the pulse frequency should be to accelerate the process, namely the start frequency is low, and then in a certain high frequency acceleration to want (Motor speed from low speed to high speed)。 Stepper motor with its remarkable characteristics, in the era of digital manufacture plays a significant purpose. With the development of digital technology and stepper motor itself, improve technology, stepping motor will be applied in more fields.
