Product Description:

The SE-LB3.033.030-14.015 synchronous servo motor is produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It serves as an electromechanical actuator that links a digital drive to mechanical loads. The motor provides closed-loop speed and position control in automated machinery such as indexing tables and pick-and-place gantries.

The A-flange and housing provide IP67 protection against temporary immersion and airborne contaminants, allowing the motor to be mounted outside a control cabinet. The integrated holding brake develops 8.0 Nm of torque to secure moderate vertical loads when power is removed. It draws only 0.8 A from a dedicated 24 VDC supply, minimizing demand on auxiliary power circuits. The electrical time constant is 7.6 ms, indicating how quickly the stator current reaches its commanded value and supporting responsive operation in high-cycle applications. The brake inertia is 0.12 × 10⁻³ kg·m², which adds little to the rotating assembly compared with typical driven-machine inertia. A winding resistance of 7.9 Ω governs steady-state thermal loss at standstill current.

Total mass, including the brake, is 9.2 kg, allowing cantilevered mounting on compact robot wrists. The rated speed is 3000 rpm, which supports direct coupling to 1:1 belt transmissions without exceeding the motor’s speed limit. A rotor inertia of 0.81 × 10⁻³ kg·m² balances acceleration capability against load decoupling. The torque constant of 1.02 Nm/A indicates how much steady torque is produced per ampere, simplifying current-loop tuning for the connected drive. The motor produces 4.2 Nm of standstill torque at a standstill current of 4.1 A. These values describe continuous operation when the shaft remains stationary during process dwell periods.
