What is the phase number of the step drive motor, and how does the user select several phases of step motor?
There is no necessary connection between the wiring and the phase number of the step motor. It depends on the actual application. For example 8 lead two/four phase motor, can be used according to the requirements and two-phase motor into 4 wire, and can also connect line root 5 or 6 thread four phase motor. Six lead wire may be 3 phase motor already, can also be 2/4 phase motor, also may be 5 phase motor. Multimeter on X1 measure, (1) can be divided into three separate windings is 3 phase motor; If the three heads are connected, and the other three are not, it is a two-fourth phase step motor. If it is a 5 phase step motor, 5 lines correspond to 5 phases, and the other is the common. I can make a list of different phase motor points. Two phase motors: the lead can be four or eight. Four phase motors: the lead can be 5, 6 or 8. Three-phase motor: the lead can be 3 or 6.
To understand the number of phases of the step motor drive, the first step is to understand the phase number of the step motor, which is the number of coils. Several phases of stepping motor are matched with several phases of drive. Two, three, four, five stages of the motor are two, three, four, five sets of coils. N phase stepper motor windings have N, N the windings shall be evenly embedded in the stator, so the number of stator poles must be N integer times, therefore, the steps of one revolution of the rotor should be integer times of N; That is to say: the steps of one revolution of the three phase stepper motor is integer times of 3, 4 steps one revolution of the stepper motor is 4 integer times, the steps of one revolution of the five phase stepper motor is 5 integer times; If the basic step for developing the stepper motor is apart from the Angle of theta, round number is M, the number of phase step motor is N have the following relations: theta = 360 / M for these mechanical symmetry principle, M is necessarily phase number N integer times. As you can see from the above analysis, the base step Angle cannot be arbitrary. There is no necessary connection between the wiring and the phase number of the step motor. It depends on the actual application.
The phase number of the step motor is the number of coils within the motor, and the two phase, three phases, four phases and five phase stepping motors are commonly used. The number of the motor is different, the Angle of the step is different, the Angle of the step distance of the second phase motor is 1.8 degrees, the third phase is 1.5 degrees, and the fifth phase is 0.72 degrees. In the absence of a breakdown driver, the user mainly selects the steps of different phases to meet the requirement of the step Angle. If you use a subdivision drive, the number of phases becomes meaningless, and the user simply changes the score on the drive to change the step Angle.
