Overview of the Schneider Electric Lexium Servo Drive and Motor Series
Servo motors are rotary or linear actuators that rotate and push machine parts with precision. Servo drives are mainly used for an angular or linear position as well as specific speed and acceleration. Today we will take a closer look at Schneider Electric Lexium servo drives ad motors.
Design and Construction of Lexium Servo Drives and Motors
A servo motor is made up of dozens of parts, each of which plays a vital role in the operation of the device. Here are its most important parts and the important roles they play in the functionality of servos.
- Stator. The stator creates a rotating magnetic field to efficiently generate torque.
- Winding. The current flowing through the winding creates a rotating magnetic field.
- Shaft - The shaft transmits the power output of the engine. This load is transmitted through a transmission mechanism.
- Rotor. The rotor is a permanent magnet located outside the shaft.
- Encoder - An optical encoder always observes and calculates the number of revolutions made and monitors the position of the shaft.
Every part of a servo motor serves a huge purpose in making the servos function or work properly.
Schneider Lexium mdrive motors BSH are low inertia AC synchronous servo motors designed for highly dynamic positioning applications. The drive system consists of a servomotor and a corresponding drive. To achieve maximum performance, the motor and drive must be matched to each other.
Servo motors are characterized by the following characteristics.
- Overload protection with built-in temperature sensor.
- Low moment of inertia.
- High power density.
- Excellent dynamics.
- High overload capacity.
- Wide torque range.
- Special winding for low-phase currents.
- Motor connection via circular connectors or terminal box.
- Easy commissioning via electronic nameplate in the SinCos encoder.
- Low costs.
The motors can be equipped with an optional shaft sealing ring. With a shaft sealing ring, they have a degree of protection IP65. The shaft sealing ring limits the maximum speed of rotation to 6000 min-1.

Programming and Control of Lexium Servo Drives and Motors
Thanks to the SinCos Hiperface rotor encoder of BSH motors, the Lexium inverter automatically obtains the nominal motor data. Manual adjustment of motor parameters is not required. The "Simply Start" menu of the PowerSuite software allows you to get the machine up and running in a matter of seconds. The Lexium auto-tuning function with a new algorithm automatically determines the optimal gains of the control loops depending on the mechanical part of the installation for various types of movement, including vertical.
BSH motors can be controlled by the Lexium servo drive in one of the many modes.
- Positioning mode: relative and absolute movements.
- Electric shaft mode.
- Speed control with position control.
- Direct speed control.
- Current regulation.
- Manual movement for ease of setup.
Easy to install, connect, configure, and operate.
- Powerful built-in software environment to facilitate the servo setup process.
- The new "auto-tuning" function allows you to get the best settings for the servo.
- The Lexium features removable, color-coded power and control connectors for easy commissioning and maintenance.
- SoMove configuration software from PC via Bluetooth or connection cable.
