Product Description:
The SE-B3.055.060-14.000 is a synchronous servo motor built by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It is intended for closed-loop industrial drives where accurate shaft positioning, repeatable velocity, and rapid torque modulation are required. Integrated feedback devices allow motion controllers to regulate the motor without mechanical gear reduction, so the unit can directly handle tasks such as pick-and-place axes, indexing tables, or secondary packaging stations that demand precise electrical control rather than pneumatic or hydraulic actuation.
The motor reaches a rated shaft speed of 3000 rpm, supporting controlled operation with a compatible servo drive. Its continuous holding capability is supported by a static torque of 6.8 Nm, ensuring that the load can be maintained whenever motion is stopped. A torque constant of 1.02 Nm/A relates drive current to mechanical output, helping the servo amplifier calculate instantaneous demand without oversizing the power stage. During acceleration or brief overloads, the drive may deliver up to 40 A. The rotor inertia of 1.21 × 10⁻³ kg·m² keeps response times short while limiting overshoot in finely tuned position loops. The standstill current is 6.7 A, and copper losses are influenced by a winding resistance of 3.53 Ω and a phase inductance of 30 mH.
For transient load spikes, the shaft can develop a maximum torque of 16.2 Nm. A back-EMF coefficient of 113 V/1000 rpm supports operation with common 560 V DC bus systems. With its brake fitted, the assembly weighs 10.9 kg and measures 295 mm in overall length. The brake releases when supplied with 24 V DC ±10% and engages when power is removed, allowing it to secure vertical axes during a power loss. The electrical time constant is 8.4 ms, reflecting the relationship between winding inductance and resistance. A 19 mm smooth shaft without a keyway supports attachment to clamp hubs or precision gearheads while avoiding the stress concentration associated with a keyway.
