Product Description:

The SE-LB3.075.060-00.100 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. This motor is intended for precision positioning and velocity control in automated machinery. It converts drive inverter commands into accurately regulated shaft motion for tasks such as pick-and-place axes, feeders, and spindle drives. Closed-loop operation allows the connected drive to adjust torque and speed as operating loads change.

The motor supports a rated speed of 6000 rpm, allowing high-cycle operation without gear reduction. At standstill, it can develop 8.2 Nm of holding torque while drawing a continuous phase current of 14 A. A torque constant of 0.58 Nm/A links current setpoints from the drive to proportional output torque. The voltage constant is 62 V/1000 rpm, providing predictable back electromotive force during operation and regenerative voltage during deceleration. Dynamic response is influenced by an electrical time constant of 9.3 ms, which indicates how quickly the current approaches its commanded value through the 0.9 Ω phase winding. These electrical values support fast closed-loop control and rapid load reversals in motion applications.

The rotor has an inertia of 1.66 × 10⁻³ kg·m², balancing quick acceleration with stable load behavior. The motor weighs 12.8 kg and measures 319 mm in overall length. Its A-flange is oil-tight, allowing installation in environments where lubricants may contact the mounting interface. Thermal saturation is moderated by a time constant of 25 min, providing time for intermittent overload operation before the winding temperature rises significantly. A centering diameter of Ø95 j6 positions the motor accurately against the mounting surface. The output interface consists of a Ø19 × 40 mm shaft with an A6 × 6 × 32 mm key for positive engagement with a coupling or pulley. The shaft permits an axial force of 133 N when the motor is connected to ball-screw or belt-driven machinery.
