What are the advantages of step-motor versus private motor?
Do you mean that servo motors have advantages over stepper motors? In turn... Stepper motor's advantage, must say yes, that is wiring simple, low prices (wiring simple actually not much, high-performance stepper motor price is not cheap). The precision of stepping motor can be much lower than servo motor, it is easy to lose step, the servo motor does not have the problem of missing step. If the drive is driven, the driver of the servo motor is much more complex than the step motor, which is the advantage of stepping into the motor. But now the driver system is a set of actuators and motors. It's not a lot of people who think about homemade drives? The workload is too heavy.
Stepping motor: can control the rotation Angle accurately, angular velocity. So it can also control the speed. A (private) clothing machine: it can control the speed of the revolution, of course, it can control the speed accurately. It's a real thing, and it's not a real thing Comparison: the speed control can be satisfied, but the need to control the angular velocity must be stepped into the motor
The servo motor has more than one feedback function, namely, one coder. The stepping motor and servo motor are both the receiver of the upper machine pulse or the analog model to control the rotation Angle and speed of the motor. But the step motor has no feedback function to run the ring. The servo motor has the encoder feedback, for the closed-loop operation. So the accuracy of the servo is higher than the step motor, and the accuracy of the servo motor depends on the encoder resolution.
