Product Description:
The SE-LB3.075.030-14.150 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It translates electrical commands from a servo controller into controlled rotary motion in automated machinery. The motor supports positioning, indexing, and continuous-speed tasks in industrial processes where regulated torque and accurate movement are required.
The motor reaches a nominal speed of 3000 rpm and delivers a static torque of 9.3 Nm, providing useful operating data for sizing a coupled gearbox or direct-drive axis. A standstill current of 9.5 A allows the motor to produce its specified static torque at zero speed. The torque constant is 0.98 Nm/A, indicating the amount of torque produced per ampere of phase current. Back EMF rises in proportion to speed according to a voltage constant of 113 V/1000 rpm, which assists with selecting a compatible inverter and DC bus. The mechanical time constant is 10.2 ms, indicating how quickly the rotor responds when torque is applied. The winding has a resistance of 2.1 Ω and an inductance of 21 mH, and these values support current-loop tuning and thermal loss calculations. These electrical characteristics should be considered with the connected drive’s current limits and control settings to maintain stable motor operation throughout the intended speed range.
The integrated brake engages in 25 ms and releases in 40 ms. It operates from a 24 V DC ±10% supply and can secure the axis when controlled by suitable brake circuitry. With the brake installed, the motor weighs 13.5 kg and has an overall length of 327 mm, providing clear values for structural loading and installation space. A 95 mm pilot diameter centers the housing within a matching precision bore. The 19 mm shaft is machined to a length of 40 mm and provides coupling space for a key, clamping hub, or backlash-free collar. The mounting structure must support the motor’s mass and maintain alignment between the shaft and the connected mechanical load. Proper alignment helps limit unwanted bearing loads and reduces stress on the selected coupling during repeated acceleration and braking cycles.
