SE-B4.170.050-00.000

The Bosch Rexroth Indramat SE-B4.170.050-00.000 servo motor from the SE Synchronous Servo Motors series offers a compact, high-performance solution for demanding motion control applications. With a minimal power loss of 25 W and a rated leakage current of 35 mA, this unit ensures energy efficiency and enhanced electrical safety in industrial environments. The motor operates on a dual-frequency supply of 50/60 Hz, allowing global compatibility and seamless integration into standard power infrastructures. Weighing just 6 kg and measuring 80 x 398 x 200 mm, the SE-B4.170.050-00.000 provides both a high power-to-weight ratio and reduced inertia for rapid acceleration and deceleration. Its torque constant of 0.58 Nm/A and voltage constant of 67 V/1000 rpm deliver precise torque generation and accurate speed control for robotics, CNC machinery, and automated assembly systems.

Detailed technical specifications are grounded in robust electrical design: the winding harness features a cross-section of conductor of 25 mm² and supports a continuous current rating of 80 A for sustained high torque output. The winding resistance of 0.37 Ohm minimizes I²R losses, while a winding inductance of 4.5 mH defines the motor’s electrical time constant of 12.3 ms. This combination yields a responsive current control loop and stable performance under dynamic load conditions. The motor’s insulation and internal structure maintain reliability up to a maximum operating temperature of 45°C, and it meets EMC Level Class A for minimized electromagnetic interference. Weight and dimensional constraints are optimized to fit compact drive cabinets and gantry systems without compromising mechanical strength.

Operational performance underscores exceptional dynamic responsiveness: the mechanical time constant of 4.1 ms signifies rapid acceleration capability, supporting high-frequency motion profiles. The precise ratio of torque to current ensures consistent torque delivery, even during rapid speed transitions. Low power dissipation ( <25 W losses) reduces thermal buildup, extending bearing and insulation life under continuous duty cycles. Integration of robust bearings and optimized cooling paths maintains performance stability across variable ambient conditions. Electromagnetic compatibility standards (Class A EMC) and minimal leakage currents further reduce system-level noise and alignment errors in sensitive measurement and control systems.

System integration is simplified by the SE-B4.170.050-00.000’s adherence to common industrial automation interfaces and drive protocols. The servo motor is directly compatible with Rexroth Indramat drive controllers, enabling advanced feedback functions and auto-tuning routines. Its compact footprint and standardized mounting facilitate retrofit into existing machines or new OEM designs in packaging, textile, and pick-and-place applications. Ideal for industries requiring precise positioning, low-vibration operation, and high throughput, this servo motor fulfils the control and performance needs of modern manufacturing systems.
