Product Description:

The SE-B3.033.030-14.150 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It serves as a compact rotary actuator for industrial automation, converting drive current into controlled torque and speed for positioning tables, gantry axes, and packaging machinery. Integrated with Rexroth digital drives, the unit helps maintain tight motion profiles where fast acceleration and stable velocity are required. Its compact design suits axes that must start, stop, and reverse direction repeatedly while maintaining accurate motion.

During operation, the motor reaches a nominal speed of 3000 rpm, which matches common servo applications that need quick cycle times and stable running speed. Each ampere delivered by the amplifier produces torque according to a constant of 1.02 Nm/A, while a static holding capacity of 4.2 Nm helps keep loads in place at zero speed. Dynamic events draw up to 24 A of phase current, whereas routine positioning uses a 4.0 A standstill level. Current in the windings rises with an electrical time constant of 5.8 ms, supporting rapid torque modulation during short indexing moves and repeated speed changes. Additional electrical data include a tacho back-EMF of 2.7 V per 1000 rpm for velocity feedback, a winding resistance of 7.9 Ω, a 1.0 Ω plug brake resistor, and a DC-link ripple tolerance of 1.5%.

Mechanical transients settle within a time constant of 7.6 ms, aided by a rotor inertia of 0.81 × 10⁻³ kg·m². When the shaft is stopped, the plug brake can absorb 785 Ws of kinetic energy before reaching its thermal limit, and the coil inductance of 60 mH helps smooth current changes from the inverter. Heat rises gradually, taking 19 minutes to approach thermal equilibrium under load. A voltage constant of 112 V per 1000 rpm relates shaft speed to back-EMF, which supports stable control behavior during acceleration and deceleration.
