Product Description:
The SE-B5.570.030-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. This unit converts three-phase electrical power into precise shaft rotation for machine tools, packaging stations, and material-handling axes. It serves as the actuating element in closed-loop drive systems where accurate speed control, high peak torque, and compact mechanical dimensions are required on industrial production lines. Its operating role suits axes that must start, stop, and reverse with repeatable motion while remaining responsive to commands from the connected drive.
The holding brake is energized at 24 V DC ±10% and produces 56 Nm of retentive torque so suspended loads remain stationary after power loss. Under rated conditions, the rotor turns at 3000 rpm and can deliver a continuous static torque of 63 Nm, which supports steady operation during constant-duty motion. During rapid indexing, the drive may command up to 369 A, supplying the current needed for fast acceleration. A surface-ventilated housing channels airflow along the 487 mm stator body, removing heat from the 51 kg assembly and permitting a maximum electromagnetic torque of 138 Nm. Combined with an inertia value of 23.6 × 10⁻3 kg·m², these characteristics support controlled acceleration and stable running under changing loads.
Electromagnetic conversion efficiency is set by a torque constant of 0.96 Nm/A, so the motor produces nearly one newton-meter for each ampere supplied. The generated back EMF follows a voltage constant of 115 V/1000 rpm, which helps the drive match motor speed to the applied voltage during operation. Phase characteristics include an inductance of 2.2 mH and a resistance of 0.094 Ω; together they affect current rise, copper loss, and heat generation at standstill. The smooth shaft supports coupling to external transmission elements without adding keyway geometry. These electrical values also affect how quickly the motor responds to current commands during low-speed and holding conditions.
