Product Description:
The SE-B5.320.030-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. It is designed for industrial automation axes that demand precise torque and velocity control, such as pick-and-place units, gantry loaders, and packaging spindles. When integrated with a compatible servo drive, the motor converts three-phase electrical power into tightly regulated rotary motion that follows position and speed commands from the machine controller. This operating role makes the motor suitable for applications that require repeatable starts, stops, and position changes during frequent duty cycles.
The unit reaches a nominal speed of 3000 rpm, allowing high cycle rates without overspeeding the rotor assembly. Its static torque rating of 38 Nm indicates the continuous stall capability, while the permissible maximum torque of 92 Nm provides short-term headroom for rapid acceleration or load changes. With a torque constant of 1.11 Nm/A, the drive produces predictable output per ampere, and the inverter must supply up to 256 A of peak phase current to use that reserve. Electrical parameters include a winding inductance of 4.6 mH and a winding resistance of 0.22 Ω, which affect current rise time, copper loss, and current-loop response. The back EMF level is characterized by a voltage constant of 118 V per 1000 rpm, which supports drive regulation during speed changes and regenerated energy flow.
A holding brake integrated at the non-drive end delivers 56 Nm to clamp the shaft when power is removed. The brake is energized by 24 VDC and draws 1.5 A during release, which supports secure holding at standstill. The circular mounting face follows a 190 mm flange pattern, and the smooth IP65 enclosure blocks dust and low-pressure water jets so the motor can be installed outside sealed cabinets. Total rotating mass is governed by a rotor inertia of 13.6 × 10⁻³ kg·m², supporting stable control on medium-load axes. Power is transmitted through a Ø32 × 58 mm shaft without a keyway, facilitating coupling with shrink-fit hubs or clamped collars while reducing stress concentrations around the shaft surface.
