Is it possible to reduce the step size if we replace the rotor and stator having different no of teeth? say 72 rotor teeth and 70 stator teeth will we get a step angle of 1.25 deg?

I have worked on many industrial robots at an automotive company, All used servo motors with encoders attached and harmonic drives. The harmonic drive is a very high ratio speed reducer and doesn't use gears so there is almost no play, The encoder is hooked directly to the motor shaft, it consist of a thin wheel with small perforations and a led on one side and light detection on the other. As the motor turns the light going through the perforations are read and counted. So when the robot goes from point a to point b the encoder keeps track of the number of flashes there probably is a 1000 or so perforations around the disc so even a very small fraction of a rotation is even monitored. So to repeat the same moment from home position 0 point the controller just runs the servo to the same point by using the encoder data stored. A little more to it than that such as it can also tell how fast it is moving and direction by the encoder. So there is where you get the extreme accuracy, even 1/1000 of the motor rotation is counted and the harmonic drive may be 50 to 100:1 ratio.

position encoder is feedback device. it is mounted directly on motor shaft (in most cases) reading motor movement and feeding it back to driver. hence the term - closed loop gathered information can be used to verify motor movement, accuracy and repeatability, compensate for high load, overload detectoin, detection an compenastion of mechanical parts wear and many more...

That is not entirely true. Servo motor has a closed loop system to achieve precision, meaning it has an encoder on the motor itself and a driver that reads encoder information to achieve/correct positioning. Many motor types can be used as a servo motor. AC servos are most commonly used, not steppers.

@craig21041981

Spot on mate AC servos are most common in automation and are completely different from stepper motors. Typically using resolvers or hyperface encoders to provide a closed loop feedback of the motor position.

This video helped me a lot to understand and visualize the topic, thanks!

Aren't the hybrid's windings wrong? I mean, their magnetic fields seems to be backwards. If we follow the current direction through the coils, every instance where it says north it should be south and vice versa.

hi guys I am helping someone with a stepper motor though I am not into motors .. I would like to use a smaller stepper motor for an application but is it possible to deliver the same torque with gears? and how does the ratio matter of the bigger and smaller stepper motor relate to each other? does 2 times a diameter deliver a 2 times higher torque?

Simple demonstration of a complicated operation. Great!!!!

Let's assume we're looking at only 1 of the 48 stator teeth. Call it tooth 'x'. Also, let's assume we're looking at only 1 of the 50 rotor teeth. Call it tooth 'y'. We know one of the following cases could occur: 1- 'y' is left-half aligned with tooth 'x' 2- 'y' is perfectly aligned with tooth 'x' 3- 'y' is right-half aligned with tooth 'x' 4- 'y' is unaligned with tooth 'x' or any other stator tooth Therefore, we have 4 possible scenarios for each rotor tooth. This means we have 50*4=200 different rotor tooth positions. We also know that rotating 1 revolution means rotating 360 degrees. Do the calculations: [360 degrees]/[200 positions] = 1.8 degrees/position

@Lesics

It is clear from the diagram. Each time the rotor has to move 1/4th of angular pitch to align with the new North pole. The special geometrical arrangement facilitates this.

hobby machines may use stepper motors, but older machines used dc brush servos and new machines use ac servos. There's really no excuse to not have closed loop feedback control in a machine that requires consistent precision.
