Product Description:

The SE-B5.320.020-04.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It is engineered to deliver closed-loop speed and torque control for automation axes that require precise positioning and repeatable velocity. In conveyor sections, tooling stations, or gantry drives, the motor converts electrical energy from a servo amplifier into tightly regulated mechanical rotation that can be synchronized with machine cycle commands. This operating profile suits machinery that must respond quickly to changing loads while maintaining stable motion.

The motor mounts to machine frames through a flange that measures 190 mm in diameter, allowing direct coupling to gearboxes or load shafts. During continuous operation, it can reach a nominal speed of 2000 rpm, which supports steady motion across a broad range of axis tasks. At zero speed, the rotor can hold a static load with 39 Nm of torque, showing the maximum shaft load that can be sustained without movement. Each ampere supplied by the drive contributes approximately 1.60 Nm/A of torque, so current demand can be estimated directly from the required load. When the shaft is locked, the windings draw a standstill current of 24 A, which helps determine holding-duty electrical demand and conductor loading.

The rotor’s inertia is 13.6 ×10⁻³ kg·m², which helps predict acceleration behavior when the motor is matched to the connected load. A holding brake supplies up to 56 Nm of torque and engages through a control circuit powered at 24 V DC ±10% to secure vertical loads when the drive is disabled. This brake arrangement helps prevent unintended movement during power-off conditions or controlled stops. Including the brake, the assembled motor weighs 37 kg, so the mounting surface and lifting method must support that mass during handling and installation.
