Product Description:
The SE-C4.170.030-14.000 is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the SE Synchronous Servo Motors series. The unit converts three-phase electrical power into tightly controlled rotation, providing the position and velocity accuracy needed for gantry drives, palletizers, and CNC feed axes in industrial automation. Its electromagnetic design supports closed-loop feedback interfaces, enabling integration with digital motion controllers that coordinate multiple axes in real time.
The motor has a nominal speed of 3000 rpm, which suits standard 1 kHz control loops. At that speed, the shaft can apply a continuous torque of 17 Nm, and short bursts can raise output to 43.0 Nm during acceleration. Those transients are supported by a peak line current of 111 A, while routine motion relies on a standstill current requirement of 19 A. The electromagnetic conversion ratio is 0.91 Nm/A, letting the drive compute torque directly from phase current feedback. Current buildup inside the windings takes 13.6 ms, and speed changes propagate through the rotor mass within a mechanical time constant of 3.5 ms. A rotor inertia of 4.08 × 10⁻³ kg·m² balances responsiveness with load stability.
When power is removed, an internal holding brake secures the shaft with 18 Nm of torque and uses a coil that draws 1.0 A from the controller’s brake output. Long-term heating is moderate, and the thermal time constant reaches 31 min, giving the motor time to absorb cyclic loads before equilibrium temperature is reached. Electrical characteristics include a phase inductance of 9.3 mH and a winding resistance of 0.68 Ω, which influence drive PWM settings and loss calculations. Back-EMF data include a voltage constant of 104 V/1000 rpm and a tachogenerator signal of 2.7 V/1000 rpm for speed regulation.
