How to understand the number of stepper motors?
The so-called "phase number" is the number of coilsTwo or three, four or five phase stepper motor, respectively, corresponding to 2, 3, 4, 5 coilN N phase stepper motor windings, the N winding should be uniformly embedded in the stator, so the number of poles of the stator must be integer times of N, therefore, the number of steps in the rotor rotates a circle should be the integer times of N; that is to say: the 3 phase stepper motor a turn step the number is an integer multiple of 3, 4 phase stepper motor to turn the step number is an integer multiple of 4, 5 phase stepper motor to turn the step number is an integer multiple of 5; if the basic step angle of stepping motor for theta, turn the number of steps is M, stepper motor the number is N has the following relation: 9 =360/M due to the mechanical principle, the M must be integer times of phase number N. According to the above analysis we can see, the basic step is not to take any value.
There is no necessary connection between the external wiring of the stepping motor and the number of phases. It is determined by the actual application needsFor example, 8 lead line two / four phase motor, according to the requirements of use and can be connected into 4 lines of two-phase motor, can also be connected to 5 lines or 6 lines of four phase motorSix lead wire may be 3 phase motor, it is also possible that 2/4 phase motor, may also be the 5 phase motor. The multimeter in X1 block measure, 1. can be divided into three independent windings 3 phase motor; 2. if three heads connected, while the other three heads is not. 2/4 phase stepping motor; if 3. is the 5 phase stepper motor, 5 lines corresponding to the 5 phase, the other one is a common end.
I can list the motors in different phases, and I would like to make a list of them1, two-phase motor: the lead line can be 4 or 82 and four phase motors: the lead line can be 5, 6 or 83, three-phase motor: the lead line can be 3 or 64 and five phase motors: the lead line can be 5, 6 or 10
