Product Description:

The SF-A5.0460.030-10.056 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. It functions as a drive-controlled actuator that delivers commanded torque and speed to automated axes in material-handling, packaging, and general motion systems. In closed-loop operation, it responds to inverter commands so rotary motion can be matched to changing load and positioning demands. Its synchronous design supports repeatable torque production during frequent starts, stops, and reversals. No mating connector is supplied, so compatible power and feedback plugs must be selected separately.

The motor is energized from a DC bus rated at 670 V, and this voltage is supplied by the inverter intermediate circuit. The drive must accommodate the corresponding back EMF as shaft speed increases during operation. During shaft lock or start-up, the winding can draw up to 29 A. Under the same stalled condition, it can resist load with 46 Nm of locked-rotor torque, which supports controlled indexing before motion begins. Once underway, it reaches a rated speed of 3000 rpm, giving a balance between throughput and mechanical life. The electromagnetic design produces torque in proportion to current at a constant of 1.58 Nm/A, which helps the servo drive regulate output in a predictable way.

A rotor inertia of 166 × 10⁻⁴ kg·m² moderates acceleration profiles, helping the axis respond quickly without becoming overly abrupt. The housing tolerates shocks up to 6 g, so the motor can be mounted on machinery that experiences rapid stops or intermittent impact. When operating, airborne sound pressure does not exceed 58 dB(A), which helps keep noise levels moderate in surrounding work areas. Two integrated temperature sensors, listed as 2 NTCs, provide thermal data for protective monitoring by the drive. This allows the control system to reduce output or stop the axis if winding temperature rises too far during repeated duty cycles. The motor uses IM B5 flange mounting, which supports standard face mounting on compatible machine structures and direct attachment to many machine frames or adapter plates.
