Product Description:
Bosch Rexroth Indramat manufactures the SE-B2.020.060-10.015 servo motor as part of the SE Synchronous Servo Motors series. The device is a permanent-magnet rotary actuator intended for closed-loop motion control in automated lines and robotic handling modules. Connected to a matching drive, it converts commanded current into repeatable torque and speed so that downstream machinery can index, position, or follow a velocity profile with the precision required in industrial production.
At its rated operating point, the motor reaches a nominal speed of 6000 rpm, delivers a static torque of 2.0 Nm, and draws a standstill current of 5.0 A. The electromagnetic conversion efficiency is characterized by a torque constant of 0.40 Nm/A, meaning each ampere supplied by the drive translates into 0.40 newton meters at the shaft. Copper losses are governed by a phase winding resistance of 4.43 Ω, and the winding inductance is 20.8 mH, which influences current ripple and servo-loop bandwidth. An electrical time constant of 10.2 ms links these values and shows how rapidly the winding current builds when a voltage step is applied. The 6.5 kg housing helps keep thermal rise moderate at this load point.
A rotor moment of inertia of 0.44 × 10⁻³ kg·m² lets the drive accelerate or decelerate the shaft quickly without oversizing the controller, and the related mechanical time constant of 4.6 ms shows that the speed loop can settle within a few milliseconds after a command change. Installation is simplified by a centering diameter of Ø95 j6, an overall body length of 230 mm, and a shaft machined to Ø14 k5 with a 30 ±0.5 mm extension that accepts standard couplings. The assembly withstands shocks up to 6 g, making it suitable for equipment that experiences rapid indexing stops or mechanical impacts during duty cycles.
