Product Description:
The SE-C4.170.030-10.150 is a synchronous servo motor produced by Bosch Rexroth Indramat in the SE Synchronous Servo Motors series. It delivers closed-loop rotary motion for automation axes and pairs with servo drives to execute precise position, speed, and torque commands on production equipment. Its synchronous design supports repeatable motion in packaging machines, transfer systems, indexing units, and other servo-controlled machinery where accurate shaft response is required.
With an electrical time constant of 13.6 ms, current in the stator windings rises quickly after the drive issues a command, supporting tight torque regulation during changes in load. This response helps the motor track command changes without sluggish current buildup. The housing carries an IP67 rating, so internal parts are sealed against dust and water exposure. Under rated conditions, the rotor reaches 3000 rpm, and short-term surges are handled by a peak phase current of 111 A; continuous holding at standstill draws 19 A. A static torque capacity of 17 Nm helps the motor overcome load inertia during startup and low-speed positioning. The IM B5 construction places a mounting flange on the drive-end face, and the smooth shaft is supplied without a keyway for clamp couplings. Electromagnetic parameters of 9.3 mH winding inductance and 0.68 Ω winding resistance shape how the motor responds to voltage pulses from the converter.
Dynamic performance also depends on a rotor inertia of 4.08 × 10⁻³ kg·m², which supports moderate acceleration without excessive current demand during indexing moves. Heat rises slowly, and the thermal time constant is 31 min, so brief overloads can be absorbed before winding temperature becomes critical. A torque constant of 0.91 Nm/A links commanded current to shaft torque, while a back-EMF value of 104 V/1000 rpm helps keep generated voltage within the drive's DC-bus range at speed. This balance of inertia, thermal behavior, and voltage generation suits axes that need frequent starts, stops, controlled speed changes, and stable torque delivery near the driven load.
