Product Description:

Bosch Rexroth Indramat manufactures the SE-LB3.095.030-10.100 as part of its SE Synchronous Servo Motors series. This synchronous servo motor delivers controlled rotary motion for feeders, pick-and-place heads, and tool drives that demand precise positioning. Integrated feedback lets Rexroth drives translate digital commands into accurate speed and torque on each axis.

The motor runs at a nominal speed of 3000 rpm, which is its rated shaft velocity under continuous load. At standstill, the windings can develop 11.6 Nm of torque, providing reliable holding capability before motion begins. The phase current at standstill is 10.5 A, while acceleration events are supported by a peak current of 63 A that the drive must supply for short periods. Electromagnetic force scales predictably because the torque constant is 1.10 Nm/A, so every ampere increases torque by slightly more than one newton-meter. Coil energy storage is represented by an inductance of 18 mH, which influences current rise time and requires matching controller bandwidth. The electrical time constant of 2.8 ms and the mechanical time constant of 10.8 ms establish how quickly the system responds to command changes.

The rotor has an inertia of 2.07 × 10^-3 kg·m², balancing quick direction changes with speed stability during cutting or indexing tasks. The thermal time constant is 35 minutes, indicating that the winding temperature rises slowly and that the motor can handle intermittent overloads without immediate overheating. Back electromotive force is characterized by a voltage constant of 118 V/1000 rpm, which the inverter uses for field-oriented control. A phase resistance of 1.68 ohms contributes to copper losses and determines the steady-state current at a given voltage. The assembly withstands shocks of up to 6 g, making it suitable for presses or gantries that experience abrupt stops. An oil-tight end plate prevents lubricant ingress. The smooth shaft is supplied without a keyway, so couplings must use clamping hubs.
