Product Description:

The 8LSA73.DB030S200-3 is a servo motor that works in sync. The usual flange size for this motor is 73 mm (millimeters). B & R Automation makes this motor with their 8LS Synchronous Motors. The speed rating for this motor is 4500 rpm. This motor features an IP65 cover for safety and cools itself by natural convection. This servo motor has a rated speed of 3000. The rated power is 6.83 kW (kilo watts) and the rated torque is 14.5 Nm (Newton-meters). The halted torque and stalled current ratings are 26 Nm and 23.64 A, respectively.

This servo motor has a Thermal Time Constant rating of 55. The Moment of Inertia without Brake J gets a score of 115, while the Weight without Brake m [kg] gets a score of 30 kg. The 8LSA73.DB030S200-3 comes with six different cords and cables, each with a different length. Utilize any kind of cable for a drag chain installation, no matter what the requirements are. Two wires are required : one for the EnDat or resolver and one for the temperature sensor and the holding brake. To keep encoder signals clear, two separate wires are employed. Users should only use B&R wires with the 8LSA73.DB030S200-3 synchronous servo motor.

This is because B&R cables make sure that the EMC threshold stays the same. Because these cables are made in the EU, not the USA, they meet the highest quality requirements. But the user may also use wires from other companies with this motor if they want to. In such scenario, they need to make sure that the cable they use has the same wave parameter as the B&R cable.
