Product Description:
Bosch Rexroth Indramat’s SE-B4.090.050-00.018 belongs to the SE Synchronous Servo Motors series and is engineered for closed-loop positioning and velocity tasks in automated machinery. As a permanent-magnet AC servo motor, it converts drive current into precise shaft rotation. This allows packaging lines, handling gantries, and tool heads to follow programmed motion profiles without mechanical backlash.
The motor’s nominal speed reaches 5000 rpm, allowing fast cycle times while staying below the mechanical limit of its 252 mm maximum overall length. During rapid acceleration, the electromagnetic circuit can deliver a maximum torque of 23.0 Nm, and the inverter may momentarily push phase current up to 85 A; continuous stall current is limited to 14 A to avoid overheating. Electromagnetic conversion efficiency is characterized by a torque constant of 0.57 Nm/A, meaning each ampere of armature current produces just over half a newton-meter of torque. Dynamic response is influenced by a winding inductance of 9.0 mH, which affects current rise time and helps guide drive filter tuning to prevent overshoot. These values indicate the electrical range required from a compatible servo drive.
The mechanical envelope centers on a 130 mm flange diameter, a Ø24 × 50 mm shaft prepared with Feather Key A8×7×40 for rigid coupling, and a housing length that caps at 252 mm. A static torque of 8.0 Nm holds loads at zero speed, while rotor inertia of 2.18 × 10-3 kg·m² limits overshoot during direction changes. Thermal capacity is summarized by a time constant of 27 min, giving the frame adequate soak time before steady-state temperature is reached. Copper losses are influenced by a winding resistance of 0.94 Ohm, and the voltage constant of 68 V/1000 rpm helps determine drive PWM voltage selection. The aluminum housing weighs 13.0 kg, adding mass that helps damp vibration and provide conduction paths for heat into the machine structure.
