What is the difference between the two-phase step motor control and the three-phase step motor control
The same size of the synchronous motor, the third phase will be more precise than the 2 phase. The owner also depends on the size of the step Angle of the machine, the smaller the Angle, the more accurate. So the torque is related to the velocity, and that's going to be the total power.
Step motor: It refers to the number of coils within the motor, which are currently used in two phases, three phases, four phases and five phase stepping motors. Step motor phase number is different, it is apart from the different Angle, the general step of the two-phase motor pitch Angle is 0.9 ° / 1.8 ° and 0.75 ° of three-phase / 1.5 ° and 0.36 ° of five phase / 0.72 °. When the driver is not broken, the user mainly depends on the step of the different phase to meet the Angle of the step. If you use a subdivision drive, the "phase number" will become meaningless, and the user simply changes the score on the drive and can change the step Angle. Now more commonly used stepping motor including reactive stepper motor (VR), permanent magnet stepper motor (PM), hybrid stepping motor (HB) and single-phase stepper motor, etc. The permanent magnet step motor is generally two phases, the torque and volume are small, and the step Angle is usually 7.5 degrees or 15 degrees. The reaction type step motor 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. The rotor magnetic circuit of the reactive step motor is made of soft magnetic material, and there is a multi-phase excitation winding on the stator, and the torque is generated by the variation of the magnetic conductance.
The two phase motor is controlled by the current of A and B, and the three-phase motor needs to control the A, B, and C three phase current. The motor should be a two phase, you choose to standard drives such as EZM552, using pure sine wave control, built-in segment function, maximum segment of 512 segments, application is very simple.
