8KS motors expand the upper range of the B&R portfolio up to 140 kW. They enable applications with a maximum stall torque of 555 Nm and speeds up to 3000 rpm. Together with B&R's servo pump controller, they are perfectly suited for high-performance servo-hydraulic drive solutions.

Cooling type 8KSC has external cooling and a centrifugal fan installed on the side (left or right). The motor is installed with the mounting flange, which also serves as a cooling surface, on a mounting base in the B-side bearing area.

Cooling type 8KSD is based on motors of cooling type 8KSC and has an additional mounting base in the A-side bearing area.

8KSJ cooling type has external cooling and cooling water connections. The motor is installed with the mounting flange, which also serves as a cooling surface, on a mounting base in the B-side bearing area. Due to the design, base mounting on the A-side is not possible with this cooling type! 

Size 9 8KSJ motors are equipped with two independent cooling circuits. The connection direction of size 8 8KSJ motors is always on the right. Size 9 must always be connected on both sides.

8KSL cooling type has external cooling and an axial fan installed on the back of the motor. The motor is installed with the mounting flange, which also serves as a cooling surface, on a mounting base in the B-side bearing area.
