Product Description:

The SE-LB3.075.060-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It serves as an electromechanical actuator that translates commanded drive currents into tightly regulated shaft rotation, making it suitable for high-speed positioning and spindle functions in automated machinery. The motor is intended for applications that require precise speed control, responsive acceleration, and stable operation during repeated motion cycles.

The motor has a nominal speed of 6000 rpm, and at this rotational rate it can deliver continuous mechanical output without overheating. Short bursts are supported by a peak current of 84 A, enabling acceleration to a maximum torque of 22.0 Nm when paired with an SM 25/50 drive module. The torque constant is 0.58 Nm/A, which relates commanded current to produced torque. A spring-applied brake is released by a control line supplied with 24 V ±10%, allowing operation from a standard control cabinet power source. Additional electrical values include a standstill current of 14 A, a static torque of 8.2 Nm, a back-EMF coefficient of 63 V/1000 rpm, a winding inductance of 8.7 mH, and a phase resistance of 0.90 Ω. These values support current control and field-oriented regulation in the matching drive.

Mechanical integration is simplified by a shaft that measures Ø19 × 40 mm and is supplied without a keyway, which supports the use of friction couplings or shrink discs. With the brake installed, the overall body length is 327 mm, allowing the motor to fit into compact machine layouts where installation space is limited. Rotor inertia is 1.66 × 10⁻³ kg·m², which helps the motor respond quickly while maintaining stable control behavior. When power is removed, the integrated brake supplies a holding torque of 8.0 Nm to secure vertical or load-bearing axes until controlled motion resumes. The assembly weighs 13.5 kg, which supports use on compact handling systems and lightweight gantries.
