Product Description:

The SE-LB3.075.030-14.015 servo motor from Bosch Rexroth is specially intended for highly advanced systems of industrial automation. The motor comes packed with a list of features that make it durability-oriented. This motor is also flexible in enabling varying operational requirements because of its accuracy and effectiveness.

In some crucial elements of its design, this SE-LB3.075.030-14.015 servo motor showcases practicality to the maximum: its voltage constant of 113V/1000rpm means that the motor can function properly even under variation in the number of rotations per minute. The winding resistance has been designed at 2.1 Ohms which is of great help in the management of power in the component when in use and in minimizing energy losses. The motor has a peak torque of 18.6 Nm permanently and an impulse torque of 9.3 Nm. Even more impressively, the dynamic response is further improved by a mechanical time constant as low as 3.3 ms. It allows the SE-LB3.075.030-14.015 servo motor for precise control and response to changes in the load condition; hence it is very highly responsive. The electric time constant is 10.2 ms, and this improves the time response of the motor when an electrical stimulation is applied. It has a stand-still current of 9.5 A, thus stressing the motor’s capacity for holding the load and delivering power when not in motion.

The rated speed of this SE-LB3.075.030-14.015 servo motor is 3000 rpm. This is achieved in a mere 30 milliseconds, to demonstrate the stunning response time that is important in activities that are time sensitive. Located within an operating temperature environment of 0 °C to 40 °C the motor is flexible to different environmental conditions. The torque constant is found to be 0.98 Nm/A helping the motor to develop a setup torque relative to the current. The thermal time constant of 32 minutes helps to maintain the motor operating temperatures without overheating when used continuously. Motor full load current circulation is 57 A at 20°C, so the ability to provide high power during full operational load can be expected.
