Product Description:

The SE-D1.010 030-04.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It delivers precise rotary motion in automated machinery that requires tight speed regulation and repetitive positioning. By converting drive current into controlled shaft torque, the unit can connect directly to ball screws, gear stages, or timing pulleys in packaging cells, pick-and-place arms, and small processing lines.

The motor develops a continuous static torque of 1.0 Nm at a nominal shaft speed of 3000 rpm. During closed-loop operation, a standstill current of 1.0 A maintains the rated torque without overheating, while a rotor inertia of 0.074 × 10⁻³ kg·m² supports quick acceleration. Dynamic response is aided by an electrical time constant of 1.36 ms, which governs the rise of current in the windings. A mechanical time constant of 5.1 ms characterizes the speed response of the rotor and connected load. The laminated stack is 227 mm long, and the stator has a winding inductance of 91.4 mH that smooths current ripple for finer velocity control. Internal copper resistance is 67.4 Ω, which limits current flow and contributes to heat generation during operation. A three-phase tachogenerator supplements drive feedback by producing 20 V peak-to-peak per phase at 1000 rpm, enabling analog speed monitoring.

A holding brake rated for 0.38 Nm locks the shaft when power is removed. The brake operates from a 24 V DC supply with a tolerance of ±10% and draws 0.21 A. With the brake installed, the assembly weighs 3.1 kg, which limits the additional frame load on vertically mounted axes. Steady torque production scales linearly with the torque constant of 1.00 Nm/A. The motor has a back-EMF voltage constant of 115 V/1000 rpm, which supports drive selection based on the intended operating speed. Thermal dissipation is influenced by the winding resistance of 67.4 Ω, which works with the coil inductance to affect electrical response and heat rise.
