B&R is adding two new sizes to its servo motors
B&R is adding two new sizes to its 8LS series of servo motors. Size A offers extremely high torque with a flange size of 70 mm and an extremely compact design, while size 9 rounds off the upper end of the perfor-mance spectrum with up to 75 kW of power. Both of these options make it possible for machine manufacturers and system integrators to adapt motors betters to actual requirements.
Compact size A motors are the perfect choice where high torque density is needed in a very tight footprint. The fully sealed stator allows a high degree of efficiency as well as high continuous torque. With a maxi-mum torque of up to 1,000 Nm, size 9 motors open up entirely new applications with high demands on pow-er and dynamics. They can be combined with any of B&R’s many gearbox options and shipped as pre-assembled motor-gearbox combinations.
All motors from the 8LS series are offered with an optional digital encoder and scalable safety functions. Motors up to size 7 are also available with B&R’s robust single-cable solution, which combines the cables for the motor and encoder. This reduces cabling to a minimum and substantially reduces installation costs.
