Basic Performance

• Maximum speed: 2 m/s to 6.5 m/s
• Maximum thrust range: 122 N to 1800 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.
• Three series are available: core (two series) and coreless (one 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.
• LM-H3 series features 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 ℃.

Higher Machine Performance

For higher machine performance

• Improved productivity due to high-speed driving part.

For easier use

• The linear servo motors enable a simple and compact machine with high rigidity.
• Smooth operation and clean systems are achieved.

For flexible machine configurations

• Multi-head and tandem systems are easily configured.
• The linear servo motors are suitable for long-stroke applications.

[Offers more advantage than conventional ball screw driving systems]

Ideal for Multi-Head Systems

• The linear servo motors configured in tandem are suitable for large systems that require highly accurate synchronous operation between two axes.
• 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-H3 Series / LM-AJ Series

LM-H3 Series / LM-AJ Series Structure

• The motor primary side consists of laminated core and motor coil. The coil is inserted into the slots on the core. The entire section is molded with resin.
• The secondary side consists of permanent magnets and a mounting plate. The permanent magnets are precisely positioned and fixed on the mounting plate, and then covered with stainless steel plate.

LM-AU Series

LM-AU Series Structure

• The motor primary side consists of motor coil and no laminated core. The coil is precisely positioned on the base, and molded with resin.
• The secondary side consists of permanent magnets and a mounting plate. The permanent magnets are precisely positioned and fixed to face each other on a U-shaped mounting plate.
