SE-C4.170.030-14.015
SE Synchronous Servo Motors
The SE-C4.170.030-14.015 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the SE Synchronous Servo Motors series. This framed-size unit is intended for precision axes in packaging equipment, handling robots, and machine tools where fast speed changes and tight velocity control are required. It works as the electromechanical link between the drive amplifier and the mechanical load, providing closed-loop torque and position response while occupying modest installation depth within a compact square flange.
The motor’s nominal speed reaches 3000 rpm, allowing a direct match to gearless transmissions that favor high shaft velocity. At standstill it can deliver 17 Nm of static torque while drawing a standstill current of 19 A, so holding forces are supplied without motion. During transient events the drive may command up to 111 A; this peak current lets the rotor generate a maximum torque of 43.0 Nm for short acceleration or shock loads. Electrical dynamics are characterized by an 13.6 ms electrical time constant, meaning current in the windings builds quickly enough for responsive torque modulation. The 142 mm flange and 24 × 50 mm shaft interface with standard IEC couplings, and the overall length stays within 315 mm when the optional holding brake is omitted.
Mechanical inertia couples with drive algorithms to let the rotor accelerate from zero to nominal speed in 35 ms, supporting short cycle duties. Each ampere produces 0.91 Nm/A of torque, and the resulting back-EMF is quantified by a voltage constant of 104 V/1000 rpm, important for sizing the DC bus. Magnetic energy storage is set by a 9.3 mH winding inductance while copper losses depend on a winding resistance of 0.68 Ω. An integrated parking brake supplies 18 Nm of holding torque to secure vertical axes when power is removed.
