Product Description:
The 8LSA44.DB060S300-3 is a three-phase servo motor designed by B & R Automation for motion control. Its supply voltage is 3 x 400 to 480 V AC, with 10% tolerance and it consumes 1885 W of normal power along with 3.7 A current. This motor comes with speedtec circular connector of size 1 for power and encoder connectivity.
The 8LSA44.DB060S300-3 servo motor delivers a rated torque of 3.0 Nm and 22.8 Nm of maximum torque. It operates at a rotational speed of 6000 rev/minute while its top attainable speed goes up to 12000 rev/minute. This motor utilizes surface cooling by convection and radiation to maintain operatable thermal condition. Its thermal time is 30 minutes to stabilize in temperature by 50 % and possess 0.0072 sec of electrical switching time for change in current. The 8LSA servo motor has an electromechanical holding brake of 8 Nm holding torque and it works on 24 VDC. Protection rating of the motor is IP64 but it can be upgraded up to IP65 with an optional seal to make the motor usable in harsh and degraded industrial surroundings. The 8LSA servo motor possess 4096 revolution period, 12 bits multiturn encoder that can resist shocks up to 2000 m/s^2 and 600 m/s^2 of vibrations.
The 8LSA44.DB060S300-3 servo motor supports both horizontally and vertically mounting positions through its flange configuration. It can be integrated with B & R ACOPOSmulti and ACOPOS P3 drives. The impedance of the stator is 0.862 ohms and the motor has a torque constant of 0.81 Nm for every 1 A of current. The 8LSA servo motor's angular inertia is equal to 0.000273 kgxm^2 and its operating thermal range is between -15 degrees C to + 40 degrees C without derating.
