Product Description:

The SE-LB3.075.030-04.000 is a servo motor produced by Bosch Rexroth Indramat to provide the kinetic energy required by industrial production and processing machines. This motor is a maintenance free device that function at an operation efficiency of about 95 percent, it is a reinforced enclosure and can withstand environmental conditions considered unfavorable for other motor designs. The SE-LB3.075.030-04.000 industrial servo motor contains permanent magnets and is intended for inverter operation with electronic commutation. The magnets present in the motor are rare-earth magnets that allows the motor to meet the dynamic operation requirements despite the low moment of inertial of the motor.

The SE-LB3.075.030-04.000 industrial servo motor has a very high demagnetization strength that is measured to be up to 6 times the standstill current it requires, it also has a broad overload range due to the stator winding which has a low thermal resistance with respect to the motor surface. The SE-LB3.075.030-04.000 is the long version of the product series, its output shaft is equipped with a keyway and feature key which ensures the efficient transmission of torque to industrial machine components. Also, there is an electrically releasing holding brake intended to retain any load connected to the motor housing when it is at a standstill.

The SE-LB3.075.030-04.000 servo motor has a rating plate which features important identification information about the motor. The construction type of the motor is according to IM V3. The cooling of this industrial motor is done through a combination of natural convection and thermal radiation, this cooling is required for the optimum operation of the motor and it is important for operators to ensure that the motor is installed in a position that exposes it to cool air.
