The same is servo, which is suitable for forging enterprise servo press?

With the continuous promotion and application of servo technology in forging industry, more and more enterprises begin to realize servo press.Which kind of servo press is suitable for forging press enterprises?

First, how it works

Stepper motor: For each input of a control pulse, the motor rotates one step at a given Angle.This Angle right here is the step Angle.Step Angle depends on the structure and driving mode of the motor.If the period of input pulse is long, the motor will turn slowly; if the period is short, the motor will turn fast.

Servo synchronous motor, servo motor itself have a pulse function, so every rotation Angle of a servo motor, send out the corresponding number of pulses, in this way, and the servo motor to accept pulse forming the echo, or closed loop, as a result, the system will know how many pulses sent to the servo motor, how much charge pulse back again at the same time, in this way, can be very precise control of the motor rotation, so as to realize accurate positioning, can reach 0.001 mm.

The difference between stepper motor and servo motor

Control mode: Stepper motor: analog control;Servo motor: Pulse control.

Control mode heat dissipation mode is different: stepper motor: fan heat dissipation;Slow heat dissipation servo motor: water cooled heat dissipation.

Different speed regulation performance: Stepper motor: poor speed regulation performance;Servo motor: switch between high speed and low speed at will.

Different overload capacity: Stepper motor: does not have overload capacity;Servo motor: it has strong overload capacity.Speed response performance is different: stepper motor: it takes 400 ms to work from rest to acceleration;Servo motor: accelerates from rest to rated speed in a few milliseconds.The difference between stepper motor and servo motor

Development of Zhengzhou Hualong Servo forging press

Stepper motor

Hualong switched from switched reluctance motors to stepper motors in 2009.However, during a short period of time from 2009 to 2010, this kind of motor was eliminated due to the high temperature of the stepper motor, the difficulty in solving the heat dissipation problem, the large starting current, the poor power saving effect and the high failure rate.

Synchronous servomotor

After hualong's constant exploration and long-term market research, we finally chose the synchronous servo motor.Compared with stepper motor, it has fast reaction speed, high-speed hammer attack, no heating of motor, and small starting current, and no impact on the power grid.The effect of electricity saving is obvious.

When everyone attention gradually to the servo press, how to choose the more suitable for forging press, fully understand the advantages and disadvantages of all kinds of servo motor, combined with the production technology of forging, synchronous servo motor drive forging press not only improve the flexibility and intelligent level of the equipment, improve the working characteristic of the press, has become a new generation of the direction of development of the press.
