Product Description:

The SF-A5.0460.030-10.068 is a synchronous servo motor built by Bosch Rexroth Indramat for the SF Servo Motors series. The unit belongs to the permanent-magnet motor range and is intended to serve as the rotary actuator inside closed-loop positioning axes found in CNC equipment, pick-and-place gantries, and other industrial automation cells. By coupling to a matched drive controller, it supplies commanded torque and speed with high repeatability, allowing motion programs to translate directly into mechanical movement across repeated positioning tasks.

During operation, the motor is supplied from a DC bus held at 670 VDC, a level typical of high-power multi-axis drive systems. Its rated speed of 3000 rpm sets the continuous operating speed limit, while the torque constant of 1.58 Nm/A links generated torque to phase current for accurate current-mode control. When the shaft is blocked, the windings can accept 29 A and produce a stall torque of 46 Nm to start static loads without external gearing. Sinusoidal back EMF supports smooth vector control, and electronic commutation removes the need for mechanical brushes. The permanent-magnet excitation creates a fixed rotor field, so dynamic response depends mainly on stator current rise time. Two integrated NTC temperature sensors report winding temperature to the drive and help prevent thermal overload.

Mechanical integration follows the IM B5 flange mounting pattern, allowing direct coupling to gearboxes or machine frames in face-mounted installations. The assembly withstands shocks up to 6 g, which helps on axes subject to sudden deceleration or tooling impact. Continuous service is specified for ambient air not exceeding 40 °C, and rated performance is maintained up to 1000 m installation altitude without derating. Electronic commutation and temperature feedback support stable operation during repeated motion cycles.
