The documented pairing
The LS590 documentation states its motor plainly: a permanent-magnet synchronous servo motor, driven with closed-loop vector control. In the documented application — hydraulic servo systems for injection moulding and similar machines — the motor drives the servo pump, and the system's published performance figures (position repeatability, pressure-holding stability, response time) belong to the drive-motor-pump combination, not to the drive alone. The drive specification is on the servo drives page.
Motor data: what is and is not published
The LS590 documentation specifies the motor type — a permanent-magnet synchronous servo motor under closed-loop vector control — and publishes the drive's model table (7.5–75 kW). It does not publish a servo motor catalogue table: motor ratings, frame dimensions and shaft details for a specific motor are not published in the LS590 documentation. If a motor is to be supplied with the drive, that is an enquiry item — state the requirement and ask what can be offered for it.
The architecture the documentation describes belongs to that hydraulic servo application: a servo motor driving a hydraulic pump, with the drive integrating injection speed and pressure-holding control alongside the machine controller's stability control. The drive's published LS590 model table (7.5–75 kW, 380 V class) fixes the drive side of the pairing; the motor side is an enquiry item, per application. Name the machine type and the pressure-holding requirement with the enquiry, and ask for the applicable documentation to be stated in the quotation.
What to send with an enquiry
- The duty: hydraulic servo pump (injection moulding, extrusion, die casting) or another servo application.
- Required power and torque, or the motor you are replacing (nameplate photo).
- Rated speed of the application and whether a pressure sensor is already fitted (the LS590 documents a pressure sensor as a necessary accessory for the hydraulic application).
- Whether one axis or several pumps in parallel (multi-pump confluence) are planned.
Where the application is a conventional VFD duty rather than a servo duty, the product index routes you to the right series instead.
The documented application
The LS590 documentation describes the drive controlling the servo pump of an injection moulding machine, integrating the process control of injection speed and pressure holding with the stability control of the machine's own controller, and lists its application fields: plastic moulding, pipe extrusion, shoe making, rubber production and metal die casting. Its stated system features include multi-pump confluence — paralleling drives for larger flow — and a built-in braking unit and braking resistor. The performance figures the documentation states for that application are on the servo drives page. When you enquire, a description of the machine and its controller is as useful as the motor data itself.
Frequently asked questions
Are motors sold separately from the LS590 drive?
The published servo line is the LS590 drive line. Motor supply for a specific application is an enquiry item — send your requirement and ask what can be offered.
What motor data is published?
The drive's documentation establishes the motor type (PMSM), the drive's model table and the system's performance figures. A separate motor table is not published in the LS590 documentation; for motor data for a specific pairing, ask with your enquiry.
Can the LS590 run an induction motor?
The LS590 documentation specifies permanent-magnet synchronous servo motors. For induction-motor duties, the VFD lines on this site are the documented route.
Send us your motor rating and application
Tell us the motor power, the supply voltage on site and what the drive will run — pump, fan, machine tool or lift. Minimum order is 1 piece on the main catalogue lines, as published on the platform store; ask for price and lead time for your model and quantity to be stated in the quotation.
