Product Description:

The SE-B4.090.030-00.000 synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. Designed for closed-loop industrial positioning tasks, the unit converts controlled electrical input into precise mechanical rotation that automation axes require. Its synchronous design supports accurate speed regulation and repeatable positioning in machinery that relies on coordinated motion. It is intended for machine axes that need consistent response during repeated start, stop, and hold cycles.

The motor mounts through a 142 mm square flange, setting the mechanical interface for gear reducers or direct-drive installations. Its die-cast housing carries an IP67 ingress rating that shields internal windings from dust and coolant splash. When the controller commands full load, the shaft can reach 17.3 Nm of maximum torque, while continuous duty is centered on 3000 rpm for stable operation. Because output torque scales linearly with current at 0.87 Nm/A, the drive can match motor demand with predictable torque response. Holding a stationary load imposes 10 A of standstill current, and the motor has a static torque of 9.0 Nm during energized idle. The 252 mm overall length and 13.0 kg mass support use in confined axes.

For dynamic profiles the drive may deliver a momentary 62 A peak current, supporting rapid acceleration before thermal limits intervene. Low combined friction and a rotor inertia of 2.18 x10^-3 kgm² allow quick velocity changes with controlled response. Electrical back-EMF is characterized by a voltage constant of 97 V per 1000 rpm, which helps predict regenerated voltage during deceleration, while the 16.1 mH phase inductance smooths switching harmonics. A winding resistance of 1.92 Ohm contributes to steady-state copper losses during continuous operation.
