Product Description:
The SE-B4.130.030-00.015 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. Designed for closed-loop positioning and speed control, the unit converts electrical energy into precise rotational movement suited to pick-and-place modules, packaging axes, and other industrial automation equipment. Its electrical and mechanical characteristics allow integration with Rexroth digital drives in applications that require compact dimensions and moderate continuous torque.
The motor develops a standstill torque of 13.8 Nm when supplied with a standstill current of 15 A, indicating its continuous torque capability at zero speed. It can accelerate from zero to rated speed with a nominal load in 36 ms, aided by an electrical time constant of 9.2 ms that permits a fast rise in winding current. A torque constant of 0.89 Nm/A relates commanded phase current to produced torque, while the back-EMF voltage constant is 105 V/1000 rpm. The winding resistance is 1.02 Ω, which affects voltage demand and current response during operation. A thermal time constant of 27 minutes indicates how quickly winding temperature changes under sustained loading and helps establish suitable operating cycles.
The A-flange has a protection rating of IP67 and a square face measuring 142 mm, supporting secure installation while resisting dust and temporary water immersion. The rotor reaches a rated speed of 3000 rpm, making the motor suitable for positioning and speed-controlled axes that require responsive motion. Its moment of inertia is 0.00308 kg·m², permitting rapid acceleration and reversal without excessive mechanical load on the drive system. The overall length without a holding brake is 283 mm, and the assembly has a mass of 16 kg, allowing installation in medium-frame machinery where size and weight must remain controlled. Power is transmitted through a shaft end with a keyway and feather key. The shaft end measures 24 mm in diameter and 50 mm in length, providing secure engagement with gears, pulleys, or rigid couplings.
