Precautions for the use of hybrid stepping motors
7 Precautions for the use of hybrid stepping motors1) The stepper motor is used in low-speed occasions --- the speed does not exceed 1000 revolutions per minute, (6666PPS at 0.9 degrees), preferably between 1000-3000PPS (0.9 degrees), and it can be used here by a deceleration device. At this time, the motor has high working efficiency and low noise.2) It is better not to use the full-step state for the stepping motor, because the vibration is large in the full-step state.3) D...

What is a synchronous motor
A synchronous motor is also an AC motor. It is mainly used as a generator, but also as a motor. It is generally used for production machinery with high power and no adjustment of speed, such as large water pumps, air compressors and mine fans. In recent years, due to the development of permanent magnet materials and electronic technology, miniature synchronous motors have become more and more widely used.One of the characteristics of a synchronous motor is that there is a str...

Working principle of synchronous motor
Establishment of the main magnetic fieldThe excitation winding is passed with a DC excitation current to establish an excitation magnetic field between polarities, that is, the main magnetic field is established.Current-carrying conductorThe three-phase symmetrical armature winding acts as a power winding and becomes the carrier of induced electric potential or induced current.Cutting motionThe prime mover drives the rotor to rotate (input mechanical energy to the motor), the...
