In this article we are going to discuss about the difference Between Stepper Motor and Servo Motor Motor Selection. Here are some general guidelines for choosing between steppers and servos: If low cost is needed, a stepper is a good choice. If loads are unpredictable and create extra torque. The stepper motor needs to be driven by a special stepper motor driver, which is composed of impulse control unit, power drive unit and protection unit. The power drive unit amplifies the pulse generated by the pulse generation control unit and is directly coupled with the stepping motor, which belongs to the power interface between the stepping motor and the microcontroller The stepping motor. The stepping motor is an open-loop control element stepping motor that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the motor speed and stop position only depend on the frequency of the pulse signal and the number of pulses, And not affected by the load change, when the stepper driver receives a pulse.

Speed-torque curves highlight the difference between stepper and AC permanent magnet (PM) servo motors of equal volume (Figure A). Steppers typically generate higher continuous torque at lower speeds than servo motors. However, servo motors produce intermittent peak torques in this same low-speed range and produce peak and continuous torques. Difference Between Stepper Motor and Servo Motor. The servo mainly depends on the pulse to position, basically can understand this way, the servo motor receives 1 pulse, will rotate the angle corresponding to 1 pulse, thus realize the displacement, because, the servo motor itself has the function that sends out the pulse, so the servo motor When rotate one angle, it will send out the. Servo and stepper motors have the same structure and use the same operating principle. Both motors include a permanent magnet rotor and a stator with wound windings. Both are operated by electricity or applying DC voltage to the stator windings, which means that the rotor moves.

AMCI's Motion Control Product Manager, Matt Tellier, presents this 20 minute webinar where he explains the topic of stepper vs servo. This video will help you fully understand the differences between stepper and servo motors, and how to select the best motor for your application. Matt covers motor basics including construction, current, functions. The only difference though between a servo (generically speaking) and a non servo motor is that the servo motor has feedback using an encoder or potentiometer. Steppers can slip and you end up losing position over time without feedback, though this only happens with heavy loads or very long time spans In a nutshell, a servo motor is a regular motor with an encoder disk on the back of the shaft that may be read by an optic. The motor has a brake as well. The motor spins, reads its position on the encoder disk and then stops the shaft upon command.
