Product Description:

The SE-B2.020.030-10.015 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for tightly controlled industrial axes, it converts electrical input from a matched drive into precise angular motion needed for positioning tables, pick-and-place heads, or light conveyor sections. Its mechanical interface follows a square A-flange, while internal windings and feedback components allow the motor to be integrated directly into servo loops that demand fast acceleration and stable speed regulation.

The A-flange carries an ingress protection rating of IP67, so the housing resists dust and temporary immersion, and a dry-running shaft seal keeps contaminants away from the bearing surfaces. When a start command is issued, the rotor reaches rated velocity in 24 ms. This acceleration profile allows short index times on packaging or assembly lines. Current in the stator builds almost instantaneously and is characterized by an electrical time constant of 5.0 ms. The motor uses the face-style IM B5 mounting pattern, simplifying alignment on gearboxes or adapter plates. Low inertia, measured at 0.44 × 10⁻³ kg·m², reduces torque demand during rapid direction changes, while the available standstill torque of 2.9 Nm supports holding loads when the shaft is motionless.

During continuous operation, the shaft turns at a nominal speed of 3000 rpm when supplied with appropriate frequency and voltage from the drive. The motor draws a standstill current of 2.7 A, which is used for sizing power stages and thermal monitoring. Its thermal time constant is 17 minutes, indicating how slowly the winding temperature rises under load before equilibrium is reached. The electromagnetic design produces torque in proportion to current with a constant of 1.10 Nm/A, and it generates a back EMF of 109 V per 1000 rpm that the drive must overcome. Copper resistance of 15 Ω affects steady-state power loss and low-speed control resolution.
