Product Description:

The SE-LB3.033.030-10.015 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. In automated machinery, it provides controlled rotary motion. This allows the drive amplifier to position loads with high repeatability and short cycle times. Its operating profile fits packaging, handling, and indexing equipment that depend on consistent servo control.

This model reaches a nominal shaft speed of 3000 rpm and can deliver a static torque of 4.2 Nm at standstill. Torque develops in proportion to current, reflected by the torque constant of 1.02 Nm/A, so 1 A of drive current produces just over one newton-meter. During acceleration, the peak current can rise to 24 A, while the mechanical time constant of 7.6 ms shows how quickly the rotor speed follows a step change in voltage. The standstill current is 4.0 A, and a winding resistance of 7.9 Ω limits steady-state thermal losses during continuous operation. Electrical dynamics are also characterized by a 5.8 ms electrical time constant and a winding inductance of 60 mH, values that guide current-loop bandwidth settings and response tuning in the drive.

A protection rating of IP67 seals the housing against dust ingress and temporary immersion. The back-EMF slope is 112 V/1000 rpm, which the inverter must accommodate during regenerative events. Thermal equilibrium is reached slowly thanks to a 19-minute thermal time constant, which means heat buildup changes gradually under sustained load, while ramp-up from zero to rated speed completes in 32 ms. The motor has a laminated steel shaft measuring 19 mm in diameter by 40 mm in length with no keyway, so couplings rely on friction or a custom hub for torque transfer. The lack of a mating connector simplifies cable selection but requires the user to supply a compatible plug for installation.
