However, there are three methods to improve the accuracy of a stepper motor. a Raspberry Pi or Arduino) to individually energise each electromagnet and make the motor shaft turn. At any given moment, it is very likely that you are near at least one or more types of motors … But (and correct me if I'm wrong) it seems servos can turn a certain ° but only up to 180° and then it needs to rotate in the other direction. However thanks to micro-stepping steppers can obtain higher resolutions. One is to use a stepper motor with more teeth. When compared to Servo Motors, Stepper Motor are considered to have low accuracy. Where a servo motor uses a continuous rotation DC motor and integrated controller circuit, stepper motors utilise multiple toothed electromagnets arranged around a central gear to define position. Apr 12, 2016, 06:55 am. Stepper motors are not as flexible with torque as are servo motors.
