Tips: Difference between 2 phase stepper motor and 4 phase stepper motor

There are two phase stepper motors, four phase stepper motor and five phase stepper motors in the market. But no matter what kind of stepper motor, their working principle is the same. When current flows through the stator winding, the stator winding generates a vector magnetic field. The magnetic field will drive the rotor to rotate in an angle, so that the pair of magnetic field directions of the rotor are consistent with the magnetic field directions of the stator. When the vector magnetic field of the stator rotates by an angle. The rotor also rotates an angle with the magnetic field. Each time an electric pulse is input, the motor rotates one angle to move forward.

The angular displacement that it outputs is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. Change the sequence of winding energization, and the motor will reverse. Therefore, the number of pulses, the frequency and the energization sequence of each phase winding of the motor can be used to control the rotation of the stepper motor.

The differences between 2 phase stepper motor and 4 phase stepper motor are:

Different internal leads: there are 4 lead wires for 2 phase motors, and there can be 5 or 6 lead wires for 4 phase motors.
Different ways of working: 2 phase permanent magnet motors have windings on the stator and the rotor is composed of soft magnetic materials. The structure is simple, the cost is low, and the step angle is small, up to 1.2 degrees. The 4 phase high torque motor is a permanent magnet stepping motor, its rotor is made of permanent magnet material, and the number of poles of the rotor is the same as that of the stator. Its characteristics are good dynamic performance and large output torque.

1.8 degree stepper motor teardown & construction display

In the case of non-overload, the speed and stop position of the motor only depend on the frequency and pulse number of the pulse signal, and are not affected by the load change. That is, when a pulse signal is added to the motor, the motor rotates through a step angle. The existence of this linear relationship, coupled with the characteristics of the stepper motor having only periodic errors and no cumulative errors. This makes it very simple to use stepper motors to control the speed, position and other control fields.

I’d give it 10 stars if I could!

This is a well-made closed loop stepper motor. It fits the standard Nema 34 stepper dimensions. Come with an enough wire. I use this stepping motor for my CNC machine, works great. I’d give it 10 stars if I could!

I’ll be ordering more!

I bought this Nema 34 closed loop stepper motor to replace my cheap one and I am sure glad I did. This stepping motor runs so quiet and cool especially with matched driver. I’ll be ordering more!
