PacDrive 3 Lexium SHS servo

Lexium SHS servo motors are stainless steel servo motors that are based on Lexium SH3 servo motors and designed for a high-torque output with relatively low current consumption in a stainless steel jacket.  Lexium SHS stainless steel servo motors and hybrid cable are the ideal choice to meet the requirements for dynamics, precision, and surroundings in the food and pharma industries.
Seven different types of Lexium SHS servo motors are available, in the following variants:

• 3 flange sizes: 055, 070, 100 mm
• Peak Torque: 3.2 to 28.3 Nm (2.36 to 20.87 ft-lbf)
• Available speed: up to 6000 rpm
• Equipped with multi-turn encoder and optionally with holding brake
• Laser marking of identifcation label

One cable solution
The range of stainless steel motors has been designed with a new type of hybrid cable to connect the drive to the motor based on a single-cable connection. This reduces the effort required for cabling and cleaning.  Lexium SHS servo motors are suitable for machines used in the food industry, which may have special requirements for materials, surfaces, soiled edges, and cleaning all parts of the machine.

General functions
Lexium SHS servo motors offer the following features:

• Overload protection with an integrated temperature sensor (external evaluation required)
• Low moment of inertia
• Excellent dynamics
• Stainless steel surface: fewer “soiled edges”, easy cleaning (CIP), hygienic design
• Certifcation to e, UL, and CSA
• Construction in accordance with EHEDG Guidelines
• Stainless steel motors are integrated in ECAM Database
• Degree of protection: IP 67 and IP 69k (shaft and housing)
• High overload capability
• Easy commissioning through electronic type plate and low maintenance
• Lexium SHS motors can be operated with Lexium 62, Lexium 52, and partly for Lexium 32. Suitable cables are available for every drive. Lexium SHS motors can also be operated with PacDrive M.

Integrated encoder
Lexium SHS servo motors are fitted with a SinCos Hiperface® high-resolution multi-turn (131,072 points/turn x 4096 turns) encoder providing angular precision of the shaft position, accurate to less than ± 1.3 arc minute (0.021°).
This performs the following functions:

• Gives the absolute motor position to allow flow synchronization
• Measures the position information for the servo drive controller
• Sends data from the servo motor to the servo drive, which allows automatic identifcation of the motor when the servo drive starts
