Product Description:
The SE-B4.090.030-05.000 servo motor is built by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It serves as a compact rotary actuator for machine tools, packaging equipment, and transfer stations where programmable drives must maintain tight velocity and position control. A 142 mm square flange and a shaft measuring 24 mm in diameter by 50 mm in length simplify mounting to standard mechanical interfaces, while the integral power terminals accept 2.5 mm² conductors.
The motor delivers a nominal speed of 3000 rpm, allowing direct coupling to gearboxes or belt stages that operate at a constant base speed. At standstill, the rotor can produce 9.0 Nm of static torque, while short-duration load demands are supported by a peak torque of 17.3 Nm. Each ampere supplied to the stator windings produces 0.87 Nm/A, allowing the drive current to be matched accurately to load requirements. The motor supports a continuous phase current of 10 A and a maximum current of 62 A for dynamic peaks. The rotor inertia is only 2.18 ×10⁻³ kg·m², supporting responsive acceleration while limiting overshoot during rapid changes in speed. The motor accelerates from standstill to its rated speed in 45 ms, providing a short ramp-up period at the beginning of each operating cycle.
Electromagnetic response is governed by an electrical time constant of 8.2 ms and a mechanical time constant of 5.1 ms. These values indicate that current and speed can settle quickly after a command change, which supports precise control during indexing and positioning movements. The laminated core stores magnetic energy through a winding inductance of 16.1 mH, while copper losses are influenced by a winding resistance of 1.92 Ω. A back EMF coefficient of 97 V/1000 rpm allows the controller to anticipate the voltage generated as the motor rotates. This generated voltage is especially relevant during deceleration, when mechanical energy can return through the motor and into the drive. The electrical characteristics support rapid motion changes, controlled dwell periods, and stable holding operation throughout an automated machine cycle.
