Product Description:

The SE-LB3.095.060-00.100 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. It provides closed-loop rotary motion for tooling, handling, and feed modules in industrial automation systems. This unit uses the long construction version and integrates an oil-tight drive-end plate, so it can mount directly to lubricant-filled gearboxes. Its Ø19 × 40 mm shaft accepts standard keyed couplings, and the overall length of 351 mm supports compact axis layouts.

The motor is rated for a nominal speed of 6000 rpm, allowing high surface velocities on spindles or linear actuators driven through belts. Under continuous operation, it delivers 9.5 Nm of static torque, giving machines enough stall capacity for holding or low-speed feed tasks. A torque constant of 0.64 Nm/A characterizes the electromagnetic conversion between current and mechanical output, so the drive controller can predict load response accurately. During acceleration or disturbance rejection, the winding can accept a peak current of 92 A, and its electrical time constant of 12.7 ms sets the current rise time that influences servo loop bandwidth. Additional values such as a voltage constant of 64 V/1000 rpm and a tachogenerator EMF of 1.8 V/1000 rpm ±5% support speed feedback and back EMF calculations for commutation.

The housing mass of 14.9 kg contributes thermal inertia, delaying temperature rise under cyclic loads. Rotor inertia is 2.07 × 10⁻³ kg·m², which balances rapid positioning with overshoot control. The magnetic circuit has a winding inductance of 8.4 mH, which filters current ripple from the power stage, and a winding resistance of 0.66 Ω, which sets copper losses at rated current. These values suit closed-loop motion applications that require stable electrical response and controlled mechanical acceleration.
