Servo motor can optimize acceleration and deceleration. Its rotor uses a small diameter to reduce inertia, and a long rotor to recover the lost torque. Of course, the inertia increases with the length of the rotor, but only linearly. From the appearance of the servo motor, it is obvious that its diameter is small but its length is large. Servo motors only need 0.05 seconds from 0 to 2000 rpm, so using variable speed servo motors to drive oil pumps can only slow down productivity in less than 5 seconds cycle. The permanent magnet is used to generate the magnetic field of the rotor, and the copper loss and iron loss of the rotor are also avoided.
Variable speed of servo motor is realized by frequency conversion principle of controller. The AC current of 50Hz or 60Hz is converted to the required frequency after rectification and drives the servo motor. Therefore, in different frequency areas, as long as the voltage is suitable, it has no effect. This is different from asynchronous motors. The rotating speed of asynchronous motor at 60Hz is 20% faster than that at 50Hz. The controller also has feedback control of pressure and speed, and PID control of pressure and flow rising and falling.
Servo motors are virtually identical to generators. What kind of function to play depends on how to drive it, supply three-phase electricity, it is a motor; supply power to rotate its spindle, it is a generator. Servo motors change into generators when braking (e.g. open-mode shutdown). Mould-locking cylinders are driven by inertia (kinetic energy) of the moving template and the moving model, and then oil pumps are driven (when the oil pump changes into an oil motor). Then the spindle of the "generator" is driven to generate voltage. After braking resistance, it turns into electric current, then into thermal energy, and emits into the atmosphere. Although this energy has not been recovered, it also serves the purpose of fast and precise braking.
