Tips: Factors that determine the step angle of a stepper motor

When the stepper motor switches the excitation current of the stator winding once, the rotor rotates by a fixed angle, that is, the step angle. The step angle is generally obtained from the rotating torque generated by the switched phase current, so the number of poles per phase is required to be an even number. Motors are usually more than two-phase, of course, there are some special single-phase motors with only one coil.

Although it is single-phase, the direction of the magnetic flux generated by a coil reverses alternately to drive the rotor to rotate. The phases of practical motors are single-phase, two-phase, three-phase, four-phase, and five-phase. Most of the stepping motors currently use permanent magnet rotors. The reason why permanent magnets are commonly used is their high efficiency and high resolution.

The factor that determines the step angle is the resolution of the motor. The higher the resolution of the stepping motor (the number of steps per revolution, 360° divided by the step angle), the higher the position accuracy. In order to obtain high resolution, the number of poles should be large. For PM type rotors, N and S poles are alternately placed on the outer surface of the rotor core at equal pitches. The number of rotor poles is the sum of the number of N poles and S poles. To simplify the explanation, assume that the number of pole pairs is 1. Here it is determined that the step angle θs of the motor whose rotor is a permanent magnet is represented by the following formula, where Nr is the number of rotor pole pairs and P is the number of stator phases.

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.

Existing reviews of Nema 23 Stepper Motor, 2 Phase, 2.5A, 0.4N·m

Quality Nema 23 stepper motor, great precision.

These are great Nema 23 stepper motors and they are very strong. I purchased 8 of these and I use them for my projects. I like them, and if the power they offer is enough for your application, these are definitely recommended for whatever you are going to do with them.

Very happy with the stepper motor.

I used this 2 phase stepper motor to replace my old one on 3D printer. It has been printing non-stop for a few weeks now and haven’t failed me. Very happy with this stepping motor. Powerful enough for the job of any of the printer functions.
