What is the difference between a servo motor and a step motor?
Low speed models Easy from the separation of the same type and general AC motor reducer a size reducer for high strength, high precision, general equipped with a variety of deceleration machine servo motor standard products. Great inertial drive The volume has shrunk dramatically
In positioning system, the most commonly used motor makes a stepper motor and servo motor, the stepper motor can be mainly divided into two phase, 5 phase, the micro stepping system, servo motor is mainly divided into two kinds of DC servo and AC servo. The following characteristics of servo motor and stepping motor are introduced: Due to the stepper motor in excitation state stops, has a great deal of retention, so even if you don't use mechanical brake can also keep the stop position (with excitation state stops, and motor current is proportional to the retention). The stepping motor is not maintained during power failure, so use the electromagnetic brake machine when the power failure is needed. It can realize the high precision positioning function of stepping motor through high precision machining. Resolution is depends on the structure of the motor, the general type HYPRID five phase stepper motor step 1 level is 0.72 ° precision depends on the machining precision of the machine, no stop precision of the load error of plus or minus 3 (plus or minus 0.05 °).

AC servo motors can be fully utilized when used in the organization shown in the left. The system is run after the X axis is run, and then run the Y-axis. In this case, it is very convenient because it can output the END of the X axis. If the X axis has an abnormal stop, it may affect other organizations. But it is very convenient because it sends a warning signal to the abnormal condition. High speed, high torque The characteristic of stepping motor is to be able to output great torque in low speed domain, but the torque will gradually decrease in high speed. AC servo motor can achieve stable high torque even in high speed. Therefore, it is suitable to use AC servo motor according to the long stroke.
