Product Description:

The SE-B2.020.060-14.000 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It converts controlled drive current into rotary motion. This supports accurate speed and position control for pick-and-place heads, light conveyor sections, and indexing tables that must accelerate quickly yet stop with high repeatability. Its compact format also suits installations where mounting space is limited.

The motor reaches a rated velocity of 6000 rpm, allowing short cycle times in small-frame machinery. At standstill it can deliver 2.0 Nm of static torque, enough to hold loads during dwell periods without mechanical locks. A torque constant of 0.40 Nm/A links commanded current to produced torque, while the continuous phase demand under zero speed is 5.0 A. The winding resistance is 4.43 Ω, and in combination with that current it contributes to copper loss and influences drive sizing. The electromagnetic circuit presents a winding inductance of 20.8 mH, which shapes current rise time and assists the controller in suppressing ripple at high PWM frequencies. A smooth Ø14 × 30 mm shaft without a keyway simplifies coupling to low-inertia pulleys or collets, and the mechanical length with the brake installed remains 260 mm, aiding installation in tight panels.

Mechanical energy stored during rapid starts is limited by a rotor inertia of 0.44 × 10⁻³ kg·m², supporting responsive acceleration while helping reduce overshoot during quick reversals. When power is removed, the integrated holding brake clamps the shaft with 3.5 Nm of torque; it releases within a 25 ms interval and re-engages just as quickly, using a 24 V DC supply that draws only 0.11 A. The complete assembly weighs 6.9 kg, so it can be mounted on moving carriages without excessive mass loading while still providing the stiffness required for precise servo loops.
