Product Description:
Bosch Rexroth Indramat manufactures the SF-A5.0460.030-10.030, a member of the SF Servo Motors series. This brushless synchronous drive element converts high-voltage DC energy into controlled rotary motion for precise positioning tasks in automated production cells. With a frame size A5 housing, the device fits compact machinery layouts while its brushless construction eliminates commutator wear, making it suited for continuous duty positioning axes.
During operation the motor is supplied from a DC bus at 670 V; the sinusoidal back-EMF profile allows the inverter to modulate current with low torque ripple. Under rated conditions the rotor reaches 3000 min⁻¹, and every ampere delivered to the windings produces 1.58 Nm/A of torque. Start-up stresses are defined by a locked-rotor current of 29 Arms which develops 46 Nm of stall torque for break-away loads. The synchronous electromagnetic circuit keeps the electrical frequency in step with mechanical speed, and the IM mounting format identified as IM B5 provides a flange interface for rigid coupling to gear stages or direct-drive loads. A sinusoidal EMF shape further minimizes audible noise at high speed and supports smooth vector control.
Control feedback and thermal monitoring are integrated. An Absolute Value Encoder on the rotor provides single-turn position data to the drive controller, removing the need for homing moves after power-up. The field is excited by a set of Permanent Magnet poles, so no external energizing current is required and dynamic response remains constant over the speed range. An electronic rating plate is embedded in the encoder memory to pass identification and parameter data to compatible drives, and temperature supervision is handled by Two NTCs embedded in the stator to signal overload before insulation limits are reached.
