Product Description:

For high-performance motion control tasks, Bosch Rexroth Indramat made the SE-B5.320.020-14.000 Servomotor. The servomotor is made with precise engineering so it works reliably in situations that need a lot of power and quick acceleration.

The SE-B5.320.020-14.000 servomotor has a peak current of 146 A at 20°C and a torque constant of 1.60 Nm/A when the temperature is 40°C. It has a moment of inertia of 13.6 × 10⁻³ kgm² and a maximum torque of 90 Nm. This makes sure that the dynamic reaction is perfect. When the motor is wound at 20°C, the winding has an inductance of 8.7 mH and a resistance of 0.47 Ohm. This motor is designed for rapid acceleration that can reach its top speed of 2000 revolutions per minute in just 37 milliseconds. This exceptional responsiveness makes it well-suited for applications requiring quick changes in speed and high precision. When stationary, the motor maintains a static torque of 39 Nm while drawing 24 Amperes (A) of current. Additionally, the motor operates efficiently under thermal conditions. At an ambient temperature of 40°C and with a winding temperature rise of 105 K, its voltage remains constant at 176 Volts per 1000 rpm.

The SE-B5.320.020-14.000 Servomotor weighs 31 kg that makes it stable mechanically. The flange is 190 mm wide that allows it to be securely mounted. The SE motor is designed to provide precise and efficient motion control by incorporating the best mechanical and electrical components. The shaft measures Ø 32 × 58 mm that makes this servomotor compatible with various mechanical coupling methods. When high torque accuracy and fast acceleration are needed, the servomotor can meet those needs.
