First, the speed of the stepping motor is much slower than that of the servo motor.
The second difference is that the resolution of the motor is higher than that of the servo motor. Linear stepper motor is a kind of motor that can directly produce direct motion without conversion equipment (such as screw rod or belt).
In this way, we can easily know the advantages of linear stepping motor compared with servo motor. Because the transmission belt (or screw rod) is removed, the start and stop of the working head is faster. Without the transmission part, of course, there is no action distortion in the transmission process.
