Product Description:

The SE-B5.700.030-14.037 servo motor is produced by Bosch Rexroth Indramat as a member of the SE Synchronous Servo Motors series. It is intended for precise rotary positioning in packaging machines, transfer lines, and similar duty-cycle-intensive equipment where accurate starts, stops, and repeatable motion are required. This operating profile suits axes that must reverse direction often and settle accurately at target positions. The motor reaches its rated mechanical speed quickly thanks to an electrical time constant of 19.0 ms and a motor inertia of 28.8 × 10⁻³ kg·m². A normally closed holding brake rated at 56 Nm keeps the load secure when power is off, and its actuation is supplied by 24 V DC at 1.5 A with an added brake inertia of 4.5 × 10⁻³ kg·m².

The motor delivers a nominal rotor speed of 3000 rpm while generating a continuous static torque of 71 Nm at standstill. During acceleration, the winding can accept up to 70 A of continuous current and a momentary peak of 446 A to overcome load inertia. Maximum torque capability tops out at 147 Nm, permitting brief overloads without demagnetization. A thermal time constant of 53 minutes allows heat to disperse gradually, which helps the motor handle intermittent high-current bursts during indexing, forming, and servo press motions.

The electromagnetic parameters support responsive control and steady current regulation across changing loads. The torque constant is 1.02 Nm/A, and the back-EMF voltage constant is 117 V/1000 rpm, matching common 560 V DC bus drives without excessive voltage margin. Low copper impedance enhances current-loop performance because phase inductance is 1.4 mH and phase resistance is 0.074 Ω. These values help the axis maintain stable torque output during rapid speed changes and repeated positioning cycles in automated assembly cells and material-handling gantries.
