Product Description:

The SE-LB3.075.060-00.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. In machine-tool axes or packaging stations, it converts drive commands from a matched servo amplifier into rotary motion for precise position and speed regulation. Its synchronous design supports closed-loop motion tasks that require repeatable response during indexing, contouring, and rapid speed changes.

At its rated speed of 6000 rpm, the rotor can follow high-frequency motion profiles without mechanical overshoot. The standstill torque of 8.2 Nm reflects the static shaft capability at zero speed, and it is achieved with a standstill current of 14 A. Each ampere delivered by the drive yields 0.58 Nm/A of torque, so load calculations can scale directly from commanded current. During constant-velocity operation, the back EMF rises linearly to 62 V/1000 rpm, which must be accommodated by the servo amplifier’s DC bus. The IM B5 flange mounting and a Ø19 × 40 mm shaft facilitate direct coupling to gearboxes or timing pulleys.

The motor has a total mass of 12.8 kg, and its overall length does not exceed 319 mm, which helps with placement in compact frames. A rotor inertia of 1.66 × 10⁻³ kg·m² moderates acceleration spikes while still allowing rapid reversal. The electrical time constant of 9.3 ms shows how quickly winding current reaches its commanded value, while the thermal time constant of 25 min reflects the period over which copper and iron temperatures stabilize during cyclic duty. The phase winding resistance is 0.9 ohm, which influences I²R losses at elevated currents. An internal tachogenerator supplies 1.8 V/1000 rpm ±5% for legacy speed loops, furnishing an analog velocity signal that parallels the digital drive feedback. This separate velocity output can also support systems that monitor speed through an analog channel alongside the main servo control loop.
