Product Description:
The SE-C4.170.030-00.015 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It converts controlled drive current into rotary motion for positioning duties in industrial automation, including pick-and-place arms, carton formers, and indexing tables. A keyed Ø24 × 50 mm shaft allows direct coupling to gearboxes or belt pulleys, while feedback from the integrated sensor enables Rexroth drives to maintain precise speed and torque control within multi-axis assemblies.
The motor reaches its rated operating point at 3000 rpm, a speed suitable for fast-cycle machines that still require high positional accuracy. At standstill, it can deliver a static torque of 17 Nm to support stationary loads while the motor remains energized. Short acceleration bursts draw up to 111 A from the inverter, and the current rises with an electrical time constant of 13.6 ms, indicating a quick electromagnetic response. The laminated stator has a winding inductance of 9.3 mH. Its winding resistance is 0.68 Ω, which affects the current-loop response of the connected drive. The standstill current is 19 A, while the mechanical time constant is 3.5 ms. The rotor reaches its reference speed from zero in a ramp-up time of 35 ms.
For peak-load events, the electromagnetic circuit provides up to 43.0 Nm of torque, giving the motor additional capacity for punch presses or rapid indexing. Dynamic behavior is influenced by a rotor inertia of 4.08 × 10⁻³ kg·m², which balances quick acceleration with smooth operation under variable loads. The winding temperature rises according to a thermal time constant of 31 min, allowing intermittent overloads without an immediate temperature increase throughout the motor. The motor produces predictable force because its flux linkage results in a torque constant of 0.91 Nm/A. A voltage constant of 104 V per 1000 rpm supports compatibility with suitable Rexroth drive outputs.
