Servo motor and stepper motor

There are more motors used in industrial production equipment, and the types of motors have different performance, so there is still a lot of choice when it is used. Now more popular is the servo motor, there is a servo motor, the servo motor is essentially a variant of the servo motor, so the two have similarities and differences, in the selection of the motor, you can refer to the performance of the two differences for targeted selection. Next, Xiaobian will tell you what the specific difference is between servo motor and stepper motor.

Precision: The application of the servo motor is relatively high in processing requirements, because it has high-precision micro-end movement ability, and the servo motor is basically used in some occasions where the requirements are not too high.

Low frequency characteristics: the performance difference between the two motors under low speed operation is also relatively large, and the stepper motor will have a relatively obvious low-frequency oscillation phenomenon, which is very unfavorable to the operation of the machine. The servo motor will be relatively stable, and there will be no obvious oscillation phenomenon.

Overload capacity: overload capacity is mainly reflected in the adaptability of the output inertia moment above, because now most of the mechanical operation will appear a large inertia moment, and the stepper motor in order to overcome this inertia moment, you need to use a larger torque model, the servo motor adaption torque is three times the rated torque, so it is very good to overcome the inertia moment.

Speed response: From the professional data point of view, the acceleration time of the servo motor needs 200-400 milliseconds, which can be accelerated to the rated speed, and the use of the servo motor takes only a few milliseconds.

Through the above performance comparison, we can find that the servo motor actually has more obvious advantages, but today's servo motor is basically higher than the price, because its cost is very high, and the production and processing requirements are not generally available to manufacturers, so when choosing the motor, you can also start from an economic point of view to see what kind of motor is really suitable for you.
