Product Description:
The SE-B5.700.020-00.015 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for closed-loop positioning and speed control, the unit converts electrical energy into regulated mechanical torque for industrial automation axes, presses, and packaging machinery. Its construction includes a 190 mm square flange and a sealed A-face, allowing direct mounting in washdown areas while protecting internal components from moisture and contaminants.
Under rated conditions, the motor reaches a nominal shaft speed of 2000 rpm, giving predictable velocity when driven by a matched inverter. The motor has a static torque rating of 74 Nm, which indicates the continuous standstill torque available without overheating. Its torque constant of 1.71 Nm/A links drive current to produced torque, which helps match the motor with an appropriate power stage. At startup, the windings draw a standstill current of 43 A, and that value affects conductor and protection selection. The electrical time constant is 21.3 ms, showing how quickly winding current rises and how fast commanded torque becomes available at the shaft.
Dynamic response is supported by a rotor inertia of 28.8 × 10⁻³ kg·m², which balances acceleration demand with load stability. The overall mass is 51 kg, and the maximum housing length is 495 mm, giving the motor a compact form for heavy gantry axes and other high-load applications. Heat generated by copper losses is absorbed over a thermal time constant of 61 min, so short overload events do not cause an immediate temperature rise. The A-face has a protection rating of IP67, which helps the motor withstand water exposure and coolant splash during operation. The shaft uses keyway and feather-key machining with a Ø32 × 58 mm output journal, and the electrical design is matched to drives that use a voltage constant of 183 V/1000 rpm and a winding resistance of 0.19 Ω.
