Product Description:

The SF-A4.0230.030-00.035 is a servo motor produced by Bosch Rexroth Indramat. It is intended for industrial automation axes that demand rapid acceleration, accurate speed regulation, and consistent positional feedback. When paired with an appropriate drive controller, the motor supplies controlled torque to conveyors, index tables, and pick-and-place modules, allowing repeatable cycle times and synchronized operation with other actuators on the line. This makes the unit suitable for packaging, transfer, and assembly equipment where axis response must remain stable during frequent start-stop cycles. Its electrical interface and feedback functions support straightforward integration into modern PLC-based motion platforms.

The motor uses a permanently excited synchronous design, which gives the rotor a fixed magnetic field for high torque density and reduced rotor heat. Because the magnetic field is created by permanent magnets rather than rotor excitation current, thermal losses stay concentrated in the stator where cooling is easier to manage. Its windings operate from a 670 V DC link, so the connected inverter must provide that intermediate bus level to reach rated speed and torque. Phase currents are switched with sinusoidal E.M.F. commutation, which helps the motor produce smooth torque with minimal cogging at low speed. Mechanical installation uses the IM B5 flange arrangement, allowing the housing to bolt directly to a machine wall while the shaft passes through to the driven load.

Position feedback is provided by an absolute value encoder, allowing the drive to recover shaft angle immediately after power is restored without a homing move. Absolute feedback also helps preserve the position reference after short power interruptions on axes that cannot tolerate repeated referencing sequences. Winding temperature is monitored by 2 NTCs, so the controller can reduce output or shut the motor down before insulation limits are exceeded. An electronic motor data memory stores motor parameters digitally, allowing the paired drive to read the stored values during startup. This supports automatic parameter recognition within the SF Servo Motors line and keeps motor identification data available to the control system.
