Product Description:

The SF-A5.0460.030-00.015 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. Designed for closed-loop position and velocity control, the unit supplies rotary motion for automated machinery that requires repeatable precision. In typical axis applications, it supports accurate starts, stops, and speed changes under servo control. It uses IM B5 construction with a flange pilot diameter of Ø180 j6, and a DIN 332-DS M12 center hole supports accurate alignment during coupling. A feather key sized A10 × 8 × 50 ensures positive torque transmission to the driven load.

During normal operation, the motor reaches a rated speed of 3000 rpm. A torque constant of 1.58 Nm/A links armature current to generated torque, helping the drive calculate setpoints for precise acceleration. When the shaft is prevented from turning, the motor can develop up to 46 Nm of locked-rotor torque while drawing 29 A, indicating strong short-term holding and load pickup capability. Total rotational inertia, including the encoder, is 166 × 10⁻⁴ kg·m², which affects how quickly the axis responds to command changes. This inertia level influences acceleration behavior, especially where fast reversals or short positioning moves are required. Two integrated NTC temperature sensors pass winding and housing data to the controller so thermal limits can be monitored during operation.

The assembly weighs 35 kg, so the mounting structure must support substantial motor mass. Torque is transferred through a shaft measuring Ø32 × 58 mm, and the keyed output supports secure coupling to the driven load. A housing depth of 383 mm must be considered where installation space is limited, particularly behind the mounting face. The drive must supply a DC-link voltage of 670 V, which matches the motor's electrical requirements for rated operation. Rear clearance is also needed for the motor body and connected hardware.
