Product Description

The SD-B5.250.020-00.000 is a brushless servomotor regulated and controlled by an SM..-T servo module for optimum performance. Manufactured by Bosch Rexroth, it is used in a wide array of servo applications in an industrial environment. This type is regulated by the SM 25/50-T module which features a host of monitoring functions such as tacho fault, PSU fault, and module fault, among others. They are mainly stored in an optional diagnostics card for an automated monitoring. Another function that ensures the SD-B5.250.020-00.000 runs as intended is the current regulator functioning.

The function compares the actual current value with the speed regulator output as a current command and sends a suitable control signal to the pulse inverter of the motor. Together with the commutation encoder, the pulse inverter controls the bridge circuit semi-conductors regulating the current in the motor windings. This enables the production of instant torque depending on the position of the rotor. The speed of the SD-B5.250.020-00.000 is monitored via the speed regulation function of the servo module. It uses three signals. An actual speed signal and two speed command signals. The SM 25/50-T unit has numerous ports such as test points, motor feedback, and control inputs, among others that provide seamless motor control.

This servo module connected to the SD-B5.250.020-00.000 motor features a rated current of 25A, maximum DC link voltage of 700V, a peak current of 50A, and maximum power loss of 200W. It should be mounted in a control cabinet that has a protection degree of IP 54 or IP 44. Forced ventilation cooling method is recommended and space of 100mm should be left above and below the module.
