Product Description:

The SE-B5.700.020-00.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It is intended for precision positioning and velocity control in automated machinery where closed-loop feedback from a drive regulates current and speed. The motor couples directly to mechanical loads, eliminating gear backlash and simplifying layouts in packaging lines, transfer stations, and material-handling axes. That direct-drive arrangement helps the axis respond smoothly during repeated starts, stops, and speed changes.

This model delivers a nominal speed of 2000 rpm and can hold a shaft at rest with a static torque of 74 Nm; during acceleration its maximum torque rises to 149 Nm. A torque constant of 1.71 Nm/A links commanded phase current to delivered torque, while the rotor moment of inertia of 28.8 ×10⁻³ kg·m² gives predictable response times under drive control. Mechanical interface details include a shaft diameter of Ø32 k5, a shaft length of 58 ±0.5 mm, and an A10 × 8 × 50 feather key that locks the shaft to couplings. The 190 ±1.5 mm flange centers the frame, and the overall motor length stays within 495 mm, which helps the motor fit in compact equipment bays. Copper losses are influenced by a winding resistance of 0.19 Ω, and a cast housing helps moderate thermal gradients around the stator windings.

An enclosure rated IP65 helps keep out dust and low-pressure water jets, supporting use on wash-down lines. Total mass is 51 kg, which can help stabilize the assembly and support heat dissipation without auxiliary cooling. The back-EMF slope of 185 V/1000 rpm means drive voltage must rise in proportion to speed, and a winding inductance of 4.2 mH influences current rise and ripple during rapid duty cycles.
