BMH0701P02A2A - servo motor - SCHNEIDER ELECTRIC

BMH and BSH servo motors:

dynamics and power BMH and BSH servo motors are three-phase synchronous type motors. They are fitted with a SinCos Hiperface® encoder for automatic transmission of data from the servo motor to the servo drive and are supplied with or without a holding brake.

BMH servo motors

BMH servo motors are medium inertia motors. They are well suited for high load applications and provide robust motion adjustment. This range covers a range of continuous torques at standstill from 1.2 to 84 Nm for a nominal speed ranging from 1200 to 5000 min-1

High performance

The Lexium 32 servo drive offer increases machine performance thanks to the following characteristics:

- overload capacity: the high peak current (up to 4 times the direct current) increases the dynamics of the movement,

- power density: the compactness of the servo drives offers maximum efficiency in a small footprint,

- high bandwidth: good speed stability and greater acceleration improve the quality of regulation,

- engine control: reduction of vibrations, speed observer and additional notch filter reinforce the quality of regulation.

A design adapted to the different automation structures

The versatility of the characteristics gives the range of Lexium 32 servo drives great flexibility for integration into different automation structures.

Depending on the model, the Lexium 32 servo drive has logic or analog inputs and outputs as standard, configurable for good adaptation to the applications.

It also has command interfaces for simple access to the different levels of architecture:

- it is equipped with a control interface for control by pulse train,

- it incorporates a combined CANopen/CANmotion port for increased automation performance,

- it also connects to major industrial communication buses and networks using various communication cards.

The following protocols are available: PROFIBUS DP V1, DeviceNet, EtherNet/IP and EtherCAT

Functions dedicated to security

The range of Lexium 32 servo drives fits into the automation safety chain by integrating the “Safe Torque Off” (STO) function which prevents accidental restarting of the servo motor. This function complies with standard IEC/EN 61508 level SIL3 on electrical installations and with power drive standard IEC/EN 61800-1. It simplifies the implementation of installations requiring a complex safety device and improves performance during maintenance operations by reducing intervention times. An additional eSM module is available to access increased security functions.
