MELSERVO-J5 Series Linear Servo Motor Features

Linear Servo Motors

Basic Performance

  • Maximum speed: 5.0 m/s (LM-H4M series), 6.5 m/s (LM-AJ series)
  • Maximum thrust range: 122 N to 7200 N. Small size and high thrust are achieved by the increased winding density and the optimized core and magnet geometries as a result of electromagnetic field analysis.
  • Seven series are available: core (three series), liquid-cooling core, magnetic attraction counter-force core, and coreless (two series) types.
  • The linear servo motors are compatible with a variety of serial interface linear encoders. The linear encoder resolution ranges from 1 nm and up.
  • High-performance systems such as high-accuracy tandem synchronous control are achieved with CC-Link IE TSN.
  • The linear servo motors feature environmental resistance, designed for an altitude of 2000 m and an ambient temperature of up to 60 ℃. *1, 2
  • *1. Derate the speed/thrust when using the linear servo motors at an altitude exceeding 1000 m and at high ambient temperatures.
  • *2. LM-AJ series/LM-AU series are designed for an altitude of 1000 m and an ambient temperature of up to 40 ℃.

Ideal for Multi-Head Systems

Optimum for a linear drive system which requires a high speed and high accuracy. Easily achieve a tandem configuration or multi-head configuration.

Tandem configuration

The linear servo motors configured in tandem are suitable for large systems that require highly accurate synchronous operation between two axes.

Tandem configuration

Multi-head configuration

Multi-head systems enable control of two motor coils independently, thereby simplifying machine mechanisms. This system is suitable for machines that require a short cycle time.

LM-H4M Series NEW

Module Connection Mechanism Patent pending

Combining the primary-side modules with a minimum unit length of 60 mm allows selection of the optimum stroke length and thrust for each application. For details of the combinations, refer to "LM-H4M Series Specifications" in "LM-H4M Series New Product Release (SV2511-1E)"

Module Connection Mechanism

High-Speed/High-Thrust/Compact

Compared with the previous model LM-H3P3, the motor is more compact and provides higher thrust, helping reduce the overall machine size. In addition, the maximum speed of 5.0 m/s leads to a shorter cycle time of the machine.

Module Connection Mechanism

Expanding Combinations of Servo Amplifiers and Linear Servo Motors

Combining the servo motor with a larger-capacity servo amplifier increases the thrust and speed, leading to a shorter cycle time of the machine.

Module Connection Mechanism

Simplified Inventory Control

The LM-H4M series uses a single type of primary-side module, eliminating the need for managing different models for each motor length as required in the previous series. This simplifies inventory and spare parts control.
Connecting the primary-side modules enables a broad thrust range, suitable for various applications and specification requirements.
