Product Description:

The SE-B4.170.050-14.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It converts drive current into controlled rotary motion, allowing machine controllers to regulate torque and speed precisely. This responsive motion supports indexing, sealing, and insertion tasks throughout automated assembly and material-handling lines.

This motor reaches a nominal velocity of 5000 rpm, giving drives a wide regulation range before field weakening becomes necessary. During continuous stall, it can hold a load with 14 Nm of static torque, indicating the maximum force available without rotor movement. Transient load surges are handled through a peak phase current of 145 A, so the inverter must support that instantaneous demand. The torque response is represented by a constant of 0.58 Nm/A, meaning each ampere supplied produces just over half a newton-meter at 20 °C. Back electromotive force at the terminals is represented by a voltage constant of 67 V/1000 rpm, which the controller uses for real-time flux estimation. A standstill current of 24 A and winding resistance of 0.37 Ω establish the continuous thermal load that the stator can dissipate under locked-shaft conditions.

Mechanical installation uses a square flange measuring 142 mm, while the housing length with the holding brake does not exceed 362 mm. The motor has a total mass of 21 kg with the electromechanical brake, which must be considered when selecting mounting hardware and vertical-axis counterbalances. Dynamic behavior is influenced by a rotor inertia of 4.08 × 10^-3 kg·m², providing a balance between quick acceleration and smooth drive response. The brake operates from a supply of 24 V DC ±10% at 1.0 A and acts on the Ø24 × 50 mm shaft. The shaft is machined without a keyway to accommodate clamp-style couplings.
