How to choose the injection molding machine servo motor

Injection molding machines are also known as injection molding machines or injection machines. It is the main molding equipment for making thermoplastic or thermosetting materials into plastic products of various shapes by using plastic molding dies. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic and applies a high pressure to the molten plastic to eject it to fill the mold cavity.

Servo motor selection:

1. Confirmation of speed and encoder resolution.

2, the calculation and selection of the regenerative resistor, for the servo, generally 2kw or more, to be configured outside.

3. Calculation of load torque on the motor shaft and calculation of acceleration and deceleration torque.

4. Calculate the load inertia and the inertia match. For example, the Yaskawa servo motor can match the inertia of some products up to 50 times, but the actual smaller the better, so the accuracy and response speed are good.

5, cable selection, encoder cable twisted shield, for the Yaskawa servo and other Japanese products absolute encoder is 6 core, incremental is 4 core.
