Product Description:
The 8JAS42.R0035D000-0 from B&R Automation is a synchronous servo motor from the 8JS line. For controlled uses, the motor works reliably because it was made for industrial automation. Natural convection is used to cool it down, and it is built with a flange fixing design. For safe operation in certain conditions, the motor has a protection class of IP54 and an insulation class of F.
With a nominal voltage of 560 VDC, the 8JAS42.R0035D000-0 servo motor can handle a minimum current of 2.18 A and a maximum current of 2.74 A. The electrical time constant is 3.4 ms and the stator inductance is 26.8 mH. This makes sure that the electrical properties are matched. The motor is made up of 5 pairs of poles and can go as fast as 3500 RPM. It makes 2.74 Nm of standard torque and 3.42 Nm of stall torque. The maximum torque is 13.1 Nm, which means it can give a lot of torque when it is needed. The end of the shaft is smooth and does not have a keyway, and there is no oil seal in the design. An encoder device called a resolver was used. It gives accurate feedback to the order of 10 angular minutes.
The size of the 8JAS42.R0035D000-0 servo motor is 4 and its length is 2, which set the limits for its compact structure. The input from the resolver works directly with the drive system to make sure that everything is in sync. The motor can work well in temperatures up to 40°C thanks to its insulation class F. This ensures that you have consistent performance and precise control across all applications.
